Abstract
Porous tantalum scaffolds offer a high degree of biocompatibility and have a low friction coefficient. In addition, their biomimetic porous structure and mechanical properties, which closely resemble human bone tissue, make them a popular area of research in the field of bone defect repair. With the rapid advancement of additive manufacturing, 3D-printed porous tantalum scaffolds have increasingly emerged in recent years, offering exceptional design flexibility, as well as facilitating the fabrication of intricate geometries and complex pore structures that similar to human anatomy. This review provides a comprehensive description of the techniques, procedures, and specific parameters involved in the 3D printing of porous tantalum scaffolds. Concurrently, the review provides a summary of the mechanical properties, osteogenesis and antibacterial properties of porous tantalum scaffolds. The use of surface modification techniques and the drug carriers can enhance the characteristics of porous tantalum scaffolds. Accordingly, the review discusses the application of these porous tantalum materials in clinical settings. Multiple studies have demonstrated that 3D-printed porous tantalum scaffolds exhibit exceptional corrosion resistance, biocompatibility, and osteogenic properties. As a result, they are considered highly suitable biomaterials for repairing bone defects. Despite the rapid development of 3D-printed porous tantalum scaffolds, they still encounter challenges and issues when used as bone defect implants in clinical applications. Ultimately, a concise overview of the primary challenges faced by 3D-printed porous tantalum scaffolds is offered, and corresponding insights to promote further exploration and advancement in this domain are presented.

Abstract
Porous tantalum (Ta) implants have been developed and clinically applied as high-quality implant biomaterials in the orthopedics field because of their excellent corrosion resistance, biocompatibility, osteointegration, and bone conductivity. Porous Ta allows fine bone ingrowth and new bone formation through the inner space because of its high porosity and interconnected pore structure. It contributes to rapid bone integration and long-term stability of osseointegrated implants. Porous Ta has excellent wetting properties and high surface energy, which facilitate the adhesion, proliferation, and mineralization of osteoblasts. Moreover, porous Ta is superior to classical metallic materials in avoiding the stress shielding effect, minimizing the loss of marginal bone, and improving primary stability because of its low elastic modulus and high friction coefficient. Accordingly, the excellent biological and mechanical properties of porous Ta are primarily responsible for its rising clinical translation trend. Over the past 2 decades, advanced fabrication strategies such as emerging manufacturing technologies, surface modification techniques, and patient-oriented designs have remarkably influenced the microstructural characteristic, bioactive performance, and clinical indications of porous Ta scaffolds. The present review offers an overview of the fabrication methods, modification techniques, and orthopedic applications of porous Ta implants.

Abstract
Regenerative medicine represents a growing hot topic in biomedical sciences, aiming at setting out novel therapeutic strategies to repair or regenerate damaged tissues and organs. For this perspective, human mesenchymal stem cells (hMSCs) play a key role in tissue regeneration, having the potential to differentiate into many cell types, including chondrocytes. Accordingly, in the last few years, researchers have focused on several in vitro strategies to optimize hMSC differentiation protocols, including those relying on epigenetic manipulations that, in turn, lead to the modulation of gene expression patterns. Therefore, in the present study, we investigated the role of the class II histone deacetylase (HDAC) inhibitor, MC1568, in the hMSCs-derived chondrogenesis. The hMSCs we used for this work were the hMSCs obtained from the amniotic fluid, given their greater differentiation capacity. Our preliminary data documented that MC1568 drove both the improvement and acceleration of hMSCs chondrogenic differentiation in vitro, since the differentiation process in MC1568-treated cells took place in about seven days, much less than that normally observed, namely 21 days. Collectively, these preliminary data might shed light on the validity of such a new differentiative protocol, in order to better assess the potential role of the epigenetic modulation in the process of the hypertrophic cartilage formation, which represents the starting point for endochondral ossification.

Laubach M, Kobbe P, Hutmacher DW. Biodegradable interbody cages for lumbar spine fusion: Current concepts and future directions. Biomaterials 2022; 288:121699. [PMID: 35995620 DOI: 10.1016/j.biomaterials.2022.121699] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 07/14/2022] [Accepted: 07/22/2022] [Indexed: 11/16/2022]
Abstract
Lumbar fusion often remains the last treatment option for various acute and chronic spinal conditions, including infectious and degenerative diseases. Placement of a cage in the intervertebral space has become a routine clinical treatment for spinal fusion surgery to provide sufficient biomechanical stability, which is required to achieve bony ingrowth of the implant. Routinely used cages for clinical application are made of titanium (Ti) or polyetheretherketone (PEEK). Ti has been used since the 1980s; however, its shortcomings, such as impaired radiographical opacity and higher elastic modulus compared to bone, have led to the development of PEEK cages, which are associated with reduced stress shielding as well as no radiographical artefacts. Since PEEK is bioinert, its osteointegration capacity is limited, which in turn enhances fibrotic tissue formation and peri-implant infections. To address shortcomings of both of these biomaterials, interdisciplinary teams have developed biodegradable cages. Rooted in promising preclinical large animal studies, a hollow cylindrical cage (Hydrosorb™) made of 70:30 poly-l-lactide-co-d, l-lactide acid (PLDLLA) was clinically studied. However, reduced bony integration and unfavourable long-term clinical outcomes prohibited its routine clinical application. More recently, scaffold-guided bone regeneration (SGBR) with application of highly porous biodegradable constructs is emerging. Advancements in additive manufacturing technology now allow the cage designs that match requirements, such as stiffness of surrounding tissues, while providing long-term biomechanical stability. A favourable clinical outcome has been observed in the treatment of various bone defects, particularly for 3D-printed composite scaffolds made of medical-grade polycaprolactone (mPCL) in combination with a ceramic filler material. Therefore, advanced cage design made of mPCL and ceramic may also carry initial high spinal forces up to the time of bony fusion and subsequently resorb without clinical side effects. Furthermore, surface modification of implants is an effective approach to simultaneously reduce microbial infection and improve tissue integration. We present a design concept for a scaffold surface which result in osteoconductive and antimicrobial properties that have the potential to achieve higher rates of fusion and less clinical complications. In this review, we explore the preclinical and clinical studies which used bioresorbable cages. Furthermore, we critically discuss the need for a cutting-edge research program that includes comprehensive preclinical in vitro and in vivo studies to enable successful translation from bench to bedside. We develop such a conceptual framework by examining the state-of-the-art literature and posing the questions that will guide this field in the coming years.

Abstract
Nanomaterials show great promise as bone regeneration materials. They can be used as fillers to strengthen bone regeneration scaffolds, or employed in their natural form as carriers for drug delivery systems. A variety of experiments have been conducted to evaluate the osteogenic potential of bone regeneration materials. In vivo, such materials are commonly tested in animal bone defect models to assess their bone regeneration potential. From an ethical standpoint, however, animal experiments should be minimized. A standardized in vitro strategy for this purpose is desirable, but at present, the results of studies conducted under a wide variety of conditions have all been evaluated equally. This review will first briefly introduce several bone regeneration reports on nanomaterials and the nanosize-derived caveats of evaluations in such studies. Then, experimental techniques (in vivo and in vitro), types of cells, culture media, fetal bovine serum, and additives will be described, with specific examples of the risks of various culture conditions leading to erroneous conclusions in biomaterial analysis. We hope that this review will create a better understanding of the evaluation of biomaterials, including nanomaterials for bone regeneration, and lead to the development of versatile assessment methods that can be widely used in biomaterial development.

Abstract
Type 1 diabetes mellitus is characterized by the destruction of pancreatic β-cells and requires the regeneration of these destroyed pancreatic β-cells for radical treatment. The degeneration of organelles in stem cells compromises stem cell quality; however, organelles in the mesenchymal stem cells of patients with type 1 diabetes mellitus have not been characterized previously. In this study, we use transmission electron microscopy to evaluate the degeneration of organelles in adipose-derived stem cells of patients with type 1 diabetes mellitus (T1DM ADSCs). Compared to adipose-derived stem cells from healthy humans, T1DM ADSCs degenerate differently, characterized by prominent enlarged spherical vesicles. The exosomes of T1DM ADSCs are found to be enlarged, reduced in number, and increased in the percentage of those positive for tetraspanin CD9. The findings of this study provide insight into the characteristics of stem cells in patients with type 1 diabetes mellitus.

Abstract
In recent years, there has been increasing interest in the treatment of bone defects using undifferentiated mesenchymal stem cells (MSCs) in vivo. Recently, dental pulp has been proposed as a promising source of pluripotent mesenchymal stem cells (MSCs), which can be used in various clinical applications. Dentin is the hard tissue that makes up teeth, and has the same composition and strength as bone. However, unlike bone, dentin is usually not remodeled under physiological conditions. Here, we generated odontoblast-like cells from mouse dental pulp stem cells and combined them with honeycomb tricalcium phosphate (TCP) with a 300 μm hole to create bone-like tissue under the skin of mice. The bone-like hard tissue produced in this study was different from bone tissue, i.e., was not resorbed by osteoclasts and was less easily absorbed than the bone tissue. It has been suggested that hard tissue-forming cells induced from dental pulp do not have the ability to induce osteoclast differentiation. Therefore, the newly created bone-like hard tissue has high potential for absorption-resistant hard tissue repair and regeneration procedures.

The Transplantation Resistance of Type II Diabetes Mellitus Adipose-Derived Stem Cells Is Due to G6PC and IGF1 Genes Related to the FoxO Signaling Pathway. Int J Mol Sci 2021; 22:ijms22126595.

Abstract
In cases of patients with rapidly progressive diabetes mellitus (DM), autologous stem cell transplantation is considered as one of the regenerative treatments. However, whether the effects of autonomous stem cell transplantation on DM patients are equivalent to transplantation of stem cells derived from healthy persons is unclear. This study revealed that adipose-derived mesenchymal stem cells (ADSC) derived from type II DM patients had lower transplantation efficiency, proliferation potency, and stemness than those derived from healthy persons, leading to a tendency to induce apoptotic cell death. To address this issue, we conducted a cyclopedic mRNA analysis using a next-generation sequencer and identified G6PC3 and IGF1, genes related to the FoxO signaling pathway, as the genes responsible for lower performance. Moreover, it was demonstrated that the lower transplantation efficiency of ADSCs derived from type II DM patients might be improved by knocking down both G6PC3 and IGF1 genes. This study clarified the difference in transplantation efficiency between ADSCs derived from type II DM patients and those derived from healthy persons and the genes responsible for the lower performance of the former. These results can provide a new strategy for stabilizing the quality of stem cells and improving the therapeutic effects of regenerative treatments on autonomous stem cell transplantation in patients with DM.

Abstract
Regenerative therapeutic approaches involving the transplantation of stem cells differentiated into insulin‐producing cells are being studied in patients with rapidly progressing severe diabetes. Adipose‐derived mesenchymal stem cells have been reported to have varied cellular characteristics depending on the biological environment of the location from which they were harvested. However, the characteristics of mesenchymal stem cells in type II diabetes have not been clarified. In this study, we observed the organelles of mesenchymal stem cells from patients with type II diabetes under a transmission electron microscope to determine the structure of stem cells in type II diabetes. Transmission electron microscopic observation of mesenchymal stem cells from healthy volunteers (N‐ADSC) and those from patients with type II diabetes (T2DM‐ADSC) revealed enlarged nuclei and degenerated mitochondrial cristae in T2DM‐ADSCs. Moreover, T2DM‐ADSCs were shown to exhibit a lower expression of Emerin, a constituent protein of the nuclear membrane, and a decreased level of mitochondrial enzyme activity. In this study, we successfully demonstrated the altered structure of nuclear membrane and the decreased mitochondrial enzyme activity in adipose‐derived mesenchymal cells from patients with type II diabetes. These findings have contributed to the understanding of type II diabetes‐associated changes in mesenchymal stem cells used for regenerative therapy.

Abstract
Mesenchymal stem cells (MSCs) have recently made significant progression in multiple clinical trials targeting several clinical disorders and in the modulation of immune responses. In the present study, we isolated human adipose tissue-derived stem cells (ADSCs) by direct membrane migration method without using enzymatic digestion via collagenase, and tried to extract adequate number of cells for clinical application. Hydroxyapatite-treated nonwoven fabric membrane made up of synthetic macromolecular fiber materials, polyethylene and polyester terephthalene was used. Expansion culture of ADSCs having plastic flask adherent characteristic in serum-free condition was successfully established, and adequate number of cells were obtained for clinical application. They were found to be positive for CD44, CD73, CD90 and CD105 and negative for CD11b, CD34, CD45, CD80 and HLA-DR. The resulting immunological marker profile satisfied the immunophenotype of previously reported MSCs. Also, microscopic findings demonstrated trilineage differentiation into adipogenic, osteogenic and chondrogenic cells as the characteristics of MSCs. The isolation by nonwoven fabric membrane and expanded cells under serum-free condition satisfied the criteria of MSCs, as proposed by the International Society for Cellular Therapy. Our direct membrane migration method without enzyme digestion is useful as ADSCs can be obtained from small pieces of adipose tissue and expanded under serum-free culture condition. This method was considered to be feasible for clinical application.

Abstract
BACKGROUND White adipose tissue (WAT) is a candidate transplantation site for islets. However, the mechanism of islet engraftment in WAT has not been fully investigated. In this study, we attempted to clarify the therapeutic effect and mechanism of islet transplantation into visceral WAT. METHODS Two hundred mouse islets were transplanted into epididymal WAT of syngeneic diabetic mice by wrapping islets with the tissue (fat-covered group). Mice that received intraperitoneal and renal subcapsular islet transplantations were used as negative and positive control groups, respectively. RESULTS The transplant efficacy, including improvements in blood glucose and plasma insulin levels and in glucose tolerance tests, of the fat-covered group was superior to the negative control group and almost equal to the positive control group. Vessel density of engrafted islets in the fat-covered group was higher than that in the positive control group. It was speculated that the mechanism of islet engraftment in WAT might consist of trapping islets in WAT, adhesion of islets via a combination of adhesion factors (fibronectin and integrin β1), and promotion of angiogenesis in islets by expression of angiogenic factors induced by adiponectin. CONCLUSIONS Visceral WAT is an important candidate for islet transplantation. Adhesion factors and adiponectin might contribute to islet engraftment into WAT. Further studies to elucidate the detailed mechanism are necessary.

Abstract
Salivary glands (SGs) are very important for maintaining the physiological functions of the mouth. When SGs regenerate and repair from various damages, including mechanical, radiological, and immune diseases, acinar and granular duct cells originate from intercalated duct cells. However, the recovery is often insufficient because of SGs' limited self-repair function. Furthermore, the precise repair mechanism has been unclear. Here, we focused on CD49f, one of the putative stem cell markers, and characterized CD49f positive cells (CD49f+ cells) isolated from male murine SGs. CD49f+ cells possess self-renewal ability and express epithelial and pluripotent markers. Compared to CD49f negative cells, freshly isolated CD49f+ cells highly expressed inhibin beta A and beta B, which are components of activin that has anti-proliferative effects. Notably, an inhibitor of activin, follistatin was expressed in mechanically-damaged SGs, meanwhile no follistatin was expressed in normal SGs in vivo. Moreover, sub-cultured CD49f+ cells highly expressed both Follistatin and a series of proliferative genes, expressions of which were decreased by Follistatin siRNA. These findings indicated that the molecular interaction between activin and follistatin may induce CD49f+ cells proliferation in the regeneration and repair of mouse SGs.

Abstract
Safety, quality, and regulatory-driven iterative optimization of therapeutic cell source selection has constituted the core developmental bedrock for primary fetal progenitor cell (FPC) therapy in Switzerland throughout three decades. Customized Fetal Transplantation Programs were pragmatically devised as straightforward workflows for tissue procurement, traceability maximization, safety, consistency, and robustness of cultured progeny cellular materials. Whole-cell bioprocessing standardization has provided plethoric insights into the adequate conjugation of modern biotechnological advances with current restraining legislative, ethical, and regulatory frameworks. Pioneer translational advances in cutaneous and musculoskeletal regenerative medicine continuously demonstrate the therapeutic potential of FPCs. Extensive technical and clinical hindsight was gathered by managing pediatric burns and geriatric ulcers in Switzerland. Concomitant industrial transposition of dermal FPC banking, following good manufacturing practices, demonstrated the extensive potential of their therapeutic value. Furthermore, in extenso, exponential revalorization of Swiss FPC technology may be achieved via the renewal of integrative model frameworks. Consideration of both longitudinal and transversal aspects of simultaneous fetal tissue differential processing allows for a better understanding of the quasi-infinite expansion potential within multi-tiered primary FPC banking. Multiple fetal tissues (e.g., skin, cartilage, tendon, muscle, bone, lung) may be simultaneously harvested and processed for adherent cell cultures, establishing a unique model for sustainable therapeutic cellular material supply chains. Here, we integrated fundamental, preclinical, clinical, and industrial developments embodying the scientific advances supported by Swiss FPC banking and we focused on advances made to date for FPCs that may be derived from a single organ donation. A renewed model of single organ donation bioprocessing is proposed, achieving sustained standards and potential production of billions of affordable and efficient therapeutic doses. Thereby, the aim is to validate the core therapeutic value proposition, to increase awareness and use of standardized protocols for translational regenerative medicine, potentially impacting millions of patients suffering from cutaneous and musculoskeletal diseases. Alternative applications of FPC banking include biopharmaceutical therapeutic product manufacturing, thereby indirectly and synergistically enhancing the power of modern therapeutic armamentariums. It is hypothesized that a single qualifying fetal organ donation is sufficient to sustain decades of scientific, medical, and industrial developments, as technological optimization and standardization enable high efficiency.

Abstract
Osteogenic and angiogenic properties are two most valued factors for bone grafting materials. Biomedical materials with synergistic promotion effects on these two properties would be highly desirable. In this study, we showed that a recently developed pH-neutral bioactive glass (PSC) possessed such characteristics. Compared to two classical biomaterials, 45S5 bioactive glass and beta-tricalcium phosphate (β-TCP), PSC markedly improved BMSCs' proliferation, migration and mineralization as well as their osteogenic and angiogenic differentiation. In vivo, PSC showed better performance on inducing bone regeneration than both 45S5 and β-TCP, as featured by elevated bone mineral density (BMD) and new bone areas. PSC also significantly promoted new blood vessels formation compared with those in control groups. Furthermore, we revealed that PSC induced osteogenic and angiogenic differentiation of BMSCs through the PI3K/Akt/HIF-1α pathway, which had not been reported before. This synergistic effect of the PI3K/Akt/HIF-1α pathway on osteogenesis and angiogenic differentiation of BMSCs suggested that biomedical materials may promote new bone formation through multiple signal pathways, thus shedding light on the future development of materials with better performance.

Abstract
OBJECTIVE To achieve bone continuity in an experimental model of segmental resection of femur bone by applying a treatment with committed to osteogenic bone linage mesenchymal stem cells. MATERIAL AND METHOD Bone marrow mesenchymal stem cells, obtained from syngeneic Wistar murine, were committed into osteogenic lineage and embedded within a hydroxipatite block. They were implanted in an experimentally created diaphyseal femur resection model. The diaphysis was synthetized with a 1.5mm thick plate. In order to calculate binomial distributions, we stablished one experimental and 3 control groups of 8 elements each: Group I, filling the gap with allograft; group ii, filling with a hydroxyapatite block without cells; group iii, filling with the hydroxyapatite block embedded with committed cells, and group iv, with the hydroxyapatite embedded with osteoinduced cells in a 3 dimensions TRAP culture. Descriptive analysis was performed by frequency distribution and Fisher statistic test. Level of statistical significance was considered at P<.05. RESULTS Group I presented good bone consolidation and no plate breakage. Group II showed fibrous but non-bone tissue, with rupture of all plates. Group III showed bone tissue in all cases, but the plates broke in all of them, while in group iv bone consolidation was achieve without any plate rupture. CONCLUSION Cell therapy with mesenchymal stem cells, trained in a 3 dimensions cell culture, produces bone tissue and ensures the permanence of the mechanical stabilization performed in a segmental resection model. LIMITATIONS A study with a larger sample size is necessary before planning the human inference.

Abstract
Ectopic 'humanized ossicles' (hOss) are miniaturized, engineered human bone organs in mice displaying a similar structure and function to native mouse bones. However, they are composed of human mesenchymal derived cells forming a humanized bone marrow niche. This in vivo reconstitution of human skeletal and hematopoietic compartments provides an opportunity to investigate the cellular and molecular processes involved in their establishment and functions in a human setting. However, current hOs strategies vary in their engineering methods and their downstream applications, undermining comprehensive exploitation of their potential. This review describes the specificities of the hOs models and highlights their potential and limits. Ultimately, we propose directions for the development of hOss as a technological platform for human hematopoietic studies.

Improved Isolation of Mesenchymal Stem Cells Based on Interactions between N-Acetylglucosamine-Bearing Polymers and Cell-Surface Vimentin. Stem Cells Int 2019; 2019:4341286.

Abstract
Mesenchymal stem cells (MSCs) in bone marrow and adipose tissues are expected to be effective tools for regenerative medicine to treat various diseases. To obtain MSCs that possess both high differentiation and tissue regenerative potential, it is necessary to establish an isolation system that does not require long-term culture. It has previously been reported that the cytoskeletal protein vimentin, expressed on the surfaces of multiple cell types, possesses N-acetylglucosamine- (GlcNAc-) binding activity. Therefore, we tried to exploit this interaction to efficiently isolate MSCs from rat bone marrow cells using GlcNAc-bearing polymer-coated dishes. Cells isolated by this method were identified as MSCs because they were CD34-, CD45-, and CD11b/c-negative and CD90-, CD29-, CD44-, CD54-, CD73-, and CD105-positive. Osteoblast, adipocyte, and chondrocyte differentiation was observed in these cells. In total, yields of rat MSCs were threefold to fourfold higher using GlcNAc-bearing polymer-coated dishes than yields using conventional tissue-culture dishes. Interestingly, MSCs isolated with GlcNAc-bearing polymer-coated dishes strongly expressed CD106, whereas those isolated with conventional tissue-culture dishes had low CD106 expression. Moreover, senescence-associated β-galactosidase activity in MSCs from GlcNAc-bearing polymer-coated dishes was lower than that in MSCs from tissue-culture dishes. These results establish an improved isolation method for high-quality MSCs.

Abstract
The stroma affects the properties and dynamics of the tumor. Previous studies have demonstrated that bone marrow-derived cells (BMDCs) possess the capability of differentiating into stromal cells. However, the characteristics and roles of BMDCs in oral squamous cell carcinoma remain unclear. The current study therefore investigated their locations and features by tracing green fluorescent protein (GFP)-labeled BMDCs in a transplantation mouse model. After irradiation, BALB-c nu-nu mice were injected with bone marrow cells from C57BL/6-BALB-C-nu/nu-GFP transgenic mice. These recipient mice were then injected subcutaneously in the head with human squamous cell carcinoma-2 cells. Immunohistochemistry for GFP, Vimentin, CD11b, CD31 and α-smooth muscle actin (SMA), and double-fluorescent immunohistochemistry for GFP-Vimentin, GFP-CD11b, GFP-CD31 and GFP-α-SMA was subsequently performed. Many round-shaped GFP-positive cells were observed in the cancer stroma, which indicated that BMDCs served a predominant role in tumorigenesis. Vimentin(+) GFP(+) cells may also be a member of the cancer-associated stroma, originating from bone marrow. Round or spindle-shaped CD11b(+) GFP(+) cells identified in the present study may be macrophages derived from bone marrow. CD31(+)GFP(+) cells exhibited a high tendency towards bone marrow-derived angioblasts. The results also indicated that spindle-shaped α-SMA(+) GFP(+) cells were not likely to represent bone marrow-derived cancer-associated fibroblasts. BMDCs gathering within the tumor microenvironment exhibited multilineage potency and participated in several important processes, such as tumorigenesis, tumor invasion and angiogenesis.

Abstract
Objectives: The aim of this research was to determine the osseointegration of two presentations of biphasic calcium phosphate (BCP) biomaterial—one untreated and another submitted to biofunctionalization with a TGF-β1 inhibitor peptide, P144, on dental alveolus. Materials and Methods: A synthetic bone graft was used, namely, (i) Maxresorb® (Botiss Klockner) (n = 12), and (ii) Maxresorb® (Botiss Klockner) biofunctionalized with P144 peptide (n = 12). Both bone grafts were implanted in the two hemimandibles of six beagle dogs in the same surgical time, immediately after tooth extraction. Two dogs were sacrificed 2, 4, and 8 weeks post implant insertion, respectively. The samples were submitted to histomorphometrical and histological analyses. For each sample, we quantified the new bone growth and the new bone formed around the biomaterial’s granules. After optical microscopic histological evaluation, selected samples were studied using backscattered scanning electron microscopy (BS-SEM). Results: The biofunctionalization of the biomaterial’s granules maintains a stable membranous bone formation throughout the experiment timeline, benefitting from the constant presence of vascular structures in the alveolar space, in a more active manner that in the control samples. Better results in the experimental groups were proven both by quantitative and qualitative analysis. Conclusions: Synthetic bone graft biofunctionalization results in slightly better quantitative parameters of the implant’s osseointegration. The qualitative histological and ultramicroscopic analysis shows that biofunctionalization may shorten the healing period of dental biomaterials.

Abstract
Introduction: Stem cells (ESC, iPSC, MSC) are known to have intrinsic regenerative properties. In the last decades numerous findings have favored the development of innovative therapeutic protocols based on the use of stem cells (Regenerative Medicine/Cell Therapy) for the treatment of numerous diseases including PAD, with promising results in preclinical studies. So far, several clinical studies have shown a general improvement of the patient's clinical outcome, however they possess many critical issues caused by the non-randomized design of the limited number of patients examined, the type cells to be used, their dosage, the short duration of treatment and also their delivery strategy. Areas covered: In this context, the use of the most advanced molecular imaging techniques will allow the visualization of very important physio-pathological processes otherwise invisible with conventional techniques, such as angiogenesis, also providing important structural and functional data. Expert opinion: The new frontier of cell therapy applied to PAD, potentially able to stop or even the process that causes the disease, with particular emphasis on the clinical aspects that different types of cells involve and on the use of more innovative molecular imaging techniques now available.

[PMID: 30721668 DOI: 10.1016/j.brainres.2019.01.037] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Revised: 01/27/2019] [Accepted: 01/29/2019] [Indexed: 12/12/2022]
Abstract
INTRODUCTION We previously established a method to isolate and culture human adipose-derived stem cells (hADSCs) using fetal bovine serum and showed the therapeutic impact on cerebral infarction. Recently, we modified the culture method with the use of serum-free media for future clinical applications. This study aims to evaluate whether intravenous administration of hADSCs induced by the serum-free culture method would improve neurobehavioral deficits in mice with cerebral infarction. RESULTS Induced hADSCs possessed the characteristics of mesenchymal stem cells and withstood a freeze-thaw process. hADSC administration improved neurobehavioral deficits in MCAO-treated mice and suppressed brain atrophy at the chronic phase. Although hADSC administration did not affect serum cytokine profiles, it decreased the number of CD11b+ monocytes in the spleen. Concomitantly, hADSC administration increased the local accumulation of CD11b+CD163+ M2 macrophages into the border zone of the cerebral infarction at 4 days post-MCAO (the acute phase). DISCUSSION Our data indicate that the systemic administration of hADSCs can improve the neurobehavioral deficits that occur after cerebral infarction by modulating the acute immune response mediated by CD11b+CD163+ M2 macrophages in infarcted lesions.

Abstract
Adipose-derived mesenchymal stem cells (ADSCs) have attracted attention due to their potential for use in the treatment of various diseases. However, the self-renewal capacity of ADSCs is restricted and their function diminishes during passage. We previously generated induced tissue-specific stem cells from mouse pancreatic cells using a single synthetic self-replicating Venezuelan Equine Encephalitis (VEE)-reprogramming factor (RF) RNA replicon (SR-RNA) expressing the reprogramming factors POU class 5 homeobox 1 (OCT4), Krueppel-like factor 4 (KLF4), Sex determining region Y-box 2 (SOX2), and Glis Family Zinc Finger 1 (GLIS1). This vector was used to generate induced pluripotent stem (iPS) cells. Here, we applied this SR-RNA vector to generate human iTS cells from aged mesenchymal stem cells (hiTS-M cells) deficient in self-renewal that were derived from adipose tissue. These hiTS-M cells transfected with the SR-RNA vector survived for 15 passages. The hiTS-M cells expressed cell surface markers similar to those of human adipose-derived mesenchymal stem cells (hADSCs) and differentiated into fat cells and osteoblasts. Global gene expression profiling showed that hiTS-M cells were transcriptionally similar to hADSCs. These data suggest that the generation of iTS cells has important implications for the clinical application of autologous stem cell transplantation.

Abstract
Cancer-associated fibroblasts (CAFs) and tumor-associated macrophages (TAMs) in tumor stroma play a key role in disease progression. Recent studies using mice models suggest that CAFs are partly derived from bone marrow and TAMs primarily originate from bone marrow-derived inflammatory monocytes. However, the origin of these cells in humans remains unclear. Hence, we investigated their human origin, using specimens from human secondary tumors that developed after sex-mismatched bone marrow transplantation, by modified immunofluorescent in situ hybridization analysis and triple immunostaining. We observed that most of the α-smooth muscle actin (αSMA)-positive CAFs in the mammary gland, liver, and oral mucosa specimens obtained 3-19 years after bone marrow transplantation are recipient-derived cells. In contrast, the majority of the peritumoral αSMA-negative fibroblast-like cells are actually bone marrow-derived HLA-DR-positive myeloid cells, such as macrophages and dendritic cells. Furthermore, almost all CD163-positive TAMs and macrophages present in the non-tumor areas are derived from bone marrow.

Abstract
Tissue engineering requires large numbers of cells with enhanced differentiation properties. Thus, the effect of expansion conditions must be explored. Human and rat marrow-derived mesenchymal stem cells (hMSCs and rMSCs, respectively) were comparatively culture expanded through seven passages in the presence of either fibroblast growth factor-2 (FGF-2) or platelet-derived growth factor BB (PDGF-BB). Proliferation of both hMSCs and rMSCs was enhanced by FGF-2 and PDGF-BB. Population doubling times for hMSCs were 2.4 days for control and 1.75 and 2.0 days for FGF-2 and PDGF-BB, respectively, and 3.25, 3.06, and 2.95 days for rMSCs. Supplementation with FGF-2 during cell expansion resulted in significantly greater in vivo bone formation for hMSCs. Use of PDGF-BB resulted in greater bone formation than that observed for control conditions, but the differences were only significant for P1. For rMSCs, significant increases in bone formation were noted in either FGF-2 or PDGF-BB expanded cells implanted at P4 or P7, but not for P1. Under in vitro osteogenic stimulation, calcium content was elevated and bone matrix deposition was enhanced for P1 and P7 rMSCs expanded with FGF-2. Although culture conditions, including FBS, were held constant, these observations suggest that medium must be optimized separately for each species of MSCs.

Abstract
Osteogenic matrix cell sheets (OMCSs) are ideal for bone regeneration. Transportation of OMCSs may be necessary, during which their osteogenic ability must be maintained. Here, we evaluated different media and temperatures for OMCS preservation. Bone marrow stromal/stem cells (BMSCs) were obtained from Fischer rats and analyzed for stem cell markers by flow cytometry. OMCSs were prepared from BMSCs by treatment with dexamethasone and ascorbic acid phosphate. After OMCS collection, they were stored in minimum essential medium (MEM) or Hank’s balanced salt solution (HBSS) at 37, 22, or 4°C for 24 hours. Cell viability and cytotoxic effects in the preservation conditions were determined by adenosine triphosphate (ATP) contents and lactate dehydrogenase (LDH) release, respectively. Osteogenesis was assessed by subcutaneously implanting preserved OMCSs around β-tricalcium phosphate ceramic disks into syngeneic rats. Implants were evaluated by alkaline phosphatase (ALP) activities, osteocalcin contents, and histology. Mesenchymal stem cells comprised 51% of primary cultured BMSCs. ATP contents were significantly different in OMCSs stored in MEM or HBSS at 22°C and 4°C. LDH release was significantly different in OMCSs stored in HBSS at 22°C and 4°C. The highest LDH release was observed in OMCSs stored in HBSS at 37°C. ALP activities and osteocalcin contents were the lowest in implanted OMCSs stored in HBSS at 37°C at four weeks after subcutaneous implantation. There was a significant difference in the osteocalcin levels of implanted OMCSs stored in MEM at 37°C and HBSS at 4°C. Abundant bone tissue around and inside disks was found in histological sections of OMCSs stored in all preservation conditions except for MEM and HBSS at 37°C. Maintaining the osteogenic ability of OMCSs during transport is important, and preservation of OMCSs in MEM or HBSS at 4°C or 22°C is a simple and inexpensive method.

Abstract
PURPOSE To evaluate whether osteogenic matrix cell sheets can supply osteogenesis to dead bone. METHODS Femur bone fragments (5 mm in length) were obtained from Fisher 344 rats and irradiated by a single exposure of 60 Gy to produce bones that were no longer viable. Osteogenic matrix cell sheets were created from rat bone marrow-derived stromal cells (BMSCs). After wrapping the dead bone with an osteogenic matrix cell sheet, it was subcutaneously transplanted into the back of a rat and harvested after 4 weeks. Bone formation around the dead bone was evaluated by X-ray imaging and histology. Alkaline phosphatase (ALP) and osteocalcin (OC) mRNA expression levels were measured to confirm osteogenesis of the transplanted bone. The contribution of donor cells to bone formation was assessed using the Sry gene and PKH26. RESULTS After the cell sheet was transplanted together with dead bone, X-ray images showed abundant calcification around the dead bone. In contrast, no newly formed bone was seen in samples that were transplanted without the cell sheet. Histological sections also showed newly formed bone around dead bone in samples transplanted with the cell sheet, whereas many empty lacunae and no newly formed bone were observed in samples transplanted without the cell sheet. ALP and OC mRNA expression levels were significantly higher in dead bones transplanted with cell sheets than in those without a cell sheet (P < 0.01). Sry gene expression and cells derived from cell sheets labeled with PKH26 were detected in samples transplanted with a cell sheet, indicating survival of donor cells after transplantation. CONCLUSION Our study indicates that osteogenic matrix cell sheet transplantation can supply osteogenesis to dead bone.

Abstract
Off-the-shelf availability in large quantities, drug delivery functionality, and modifiable chemistry and mechanical properties make synthetic polymers highly suitable candidates for bone grafting. However, most synthetic polymers lack the ability to support cell attachment, proliferation, migration, and differentiation, and ultimately tissue formation. Incorporating anionic peptides into the polymer that mimics acidic proteins, which contribute to biomineralization and cellular attachment, could enhance bone formation. Therefore, this study investigates the effect of a phosphate functional group on osteoconductivity and BMP-2-induced bone formation in an injectable and biodegradable oligo[(polyethylene glycol) fumarate] (OPF) hydrogel. Three types of OPF hydrogels were fabricated using 0%, 20%, or 40% Bis(2-(methacryloyloxy)ethyl) phosphate creating unmodified OPF-noBP and phosphate-modified OPF-BP20 and OPF-BP40, respectively. To account for the osteoinductive effect of various BMP-2 release profiles, two different release profiles (i.e., different ratios of burst and sustained release) were obtained by varying the BMP-2 loading method. To investigate the osteoconductive effect of phosphate modification, unloaded OPF composites were assessed for bone formation in a bone defect model after 3, 6, and 9 weeks. To determine the effect of the hydrogel phosphate modification on BMP-2-induced bone formation, BMP-2 loaded OPF composites with differential BMP-2 release were analyzed after 9 weeks of subcutaneous implantation in rats. The phosphate-modified OPF hydrogels (OPF-BP20 and OPF-BP40) generated significantly more bone in an orthotopic defect compared to the unmodified hydrogel (OPF-noBP). Furthermore, the phosphate functionalized surface-enhanced BMP-2-induced ectopic bone formation regardless of the BMP-2 release profile. In conclusion, this study clearly shows that phosphate functional groups improve the osteoconductive properties of OPF and enhanced BMP-2-induced bone formation. Therefore, functionalizing hydrogels with phosphate groups by crosslinking monomers into the hydrogel matrix could provide a valuable method for improving polymer characteristics and holds great promise for bone tissue engineering.

Abstract
Microfluidic technologies employ nano and microscale fabrication techniques to develop highly controllable and reproducible fluidic microenvironments. Utilizing microfluidics, lead compounds can be produced with the controlled physicochemical properties, characterized in a high-throughput fashion, and evaluated in in vitro biomimetic models of human organs; organ-on-a-chip. As a step forward from conventional in vitro culture methods, microfluidics shows promise in effective preclinical testing of nanoparticle-based drug delivery. This review presents a curated selection of state-of-the-art microfluidic platforms focusing on the fabrication, characterization, and assessment of nanoparticles for drug delivery applications.

Abstract
Chondrogenic cell differentiation constitutes a multistep program that is spatially and temporally modulated by combinations of bioactive factors that drives the establishment of specific cellular phenotypes. This sequence of events results in the fabrication of a distinctive structural and functional extracellular matrix which determines the quality of the cartilaginous tissue and, thus, its potential in vivo implantability as a tissue-engineered implant. Current assessments of engineered cartilage rely on destructive methodologies typically applied at the end of the fabrication period that make it difficult to predict failures early in the process. The high inherent variability of engineered tissues raises questions regarding reproducibility and the validity of using such end-stage representative samples to characterize an entire batch of engineered tissues. Therefore, the development of dynamic, multimodal, nondestructive, and noninvasive technology toolsets to monitor cell differentiation (and secondarily tissue phenotypes) in real time is of paramount importance. In this study, we report the creation of cell-based probes to directly interrogate cell differentiation events during in vitro chondrogenesis and in vivo osteogenesis. For that, native promoters of well-established chondrogenic (Sex Determining Region Y-Box 9 [Sox9] and Aggrecan [AGG]) and osteogenic (Osteocalcin [OC]) differentiation biomarkers were used to create independent probes incorporating a traceable signal (Luciferase) and transduced into human bone marrow-derived mesenchymal stem cells. The probes were used to monitor the progression throughout in vitro chondrogenic differentiation program in aggregate (pellet) cultures and in vivo osteogenic differentiation in heterotopic ossicles. These tissue differentiation constructs were positively tested in conditions known to modulate the differentiation program at various phases that confirmed their sensitivity and reproducibility. This technology toolset allows a nondestructive and noninvasive, imaging-based longitudinal reconstruction of the in vitro chondrogenic differentiation program, while providing an analytical assessment of phenotypic changes of engineered cartilage in real time.

Abstract
Multipotential ability of bone marrow-derived cells has been clarified, and their involvement in repair and maintenance of various tissues has been reported. However, the role of bone marrow-derived cells in osteogenesis remains unknown. In the present study, bone marrow-derived cells during ectopic bone formation of mouse femoral muscle were traced using a GFP bone marrow transplantation model. Bone marrow cells from C57BL/6-Tg (CAG-EGFP) mice were transplanted into C57BL/6 J wild type mice. After transplantation, insoluble bone matrix (IBM) was implanted into mouse muscle. Ectopic bone formation was histologically assessed at postoperative days 7, 14, and 28. Immunohistochemistry for GFP single staining and GFP-osteocalcin double staining was then performed. Bone marrow transplantation successfully replaced hematopoietic cells with GFP-positive donor cells. Immunohistochemical analyses revealed that osteoblasts and osteocytes involved in ectopic bone formation were GFP-negative, whereas osteoclasts and hematopoietic cells involved in bone formation were GFP-positive. These results indicate that bone marrow-derived cells might not differentiate into osteoblasts. Thus, the main role of bone marrow-derived cells in ectopic osteogenesis may not be to induce bone regeneration by differentiation into osteoblasts, but rather to contribute to microenvironment formation for bone formation by differentiating tissue stem cells into osteoblasts.

Tissue Eng Regen Med 2017; 15:89-100. [PMID: 30603537 DOI: 10.1007/s13770-017-0088-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2017] [Revised: 08/14/2017] [Accepted: 09/26/2017] [Indexed: 01/22/2023] Open
Abstract
The purpose of this study was to evaluate the osteogenesis ability of osteogenic matrix cell sheets (OMCS) derived from old donor cells. Bone marrow stromal cells (BMSC) were obtained from young (7-week-old) and old (1-year-old) Fischer344 rats donors and cultured with modified Eagle's medium (MEM group) alone or containing dexamethasone (Dex; 10 nM) and ascorbic acid phosphate (AscP; 0.28 mM) (Dex/AscP group). We prepared four in vitro experimental groups: (1) young MEM, (2) young Dex/AscP, (3) old MEM and (4) old Dex/AscP. Cell proliferation and osteogenic marker mRNA expression levels were evaluated in vitro. To assess bone formation in vivo, the cells of each group were combined with beta tricalcium phosphate (TCP) disks followed by implantation in recipient rats. The in vitro study showed significant differences in the mRNA expression of osteocalcin, ALP, and BMP2 between MEM and Dex/AscP groups. Bone formation following implantation was observed upon histological analyses of all groups. TCP combined with OMCS (OMCS/TCP group) resulted in enhanced bone formation compared to that following combination with BMSC (BMSC/TCP). The osteocalcin content of the OMCS/TCP group 4 weeks after implantation was significantly higher than that in the BMSC/TCP construct for both young and old donors. The present study clearly indicated that OMCS could be generated from BMSCs of old as well as young donors using a mechanical retrieval method. Thus, through its usage of OMCS, this method may represent a potentially effective therapeutic option for cell-based therapy in elderly patients.

Abstract
PURPOSE The treatment outcomes for inflammatory bowel disease (IBD) have been improving, but the development of better therapies is needed. Stem cell therapy is promising, but little is known about the differences in adipose-derived stem cells (ADSCs) between IBD patients and healthy individuals. METHODS ADSCs were isolated from subcutaneous adipose tissue (SAT) in IBD (Crohn's disease, 3; ulcerative colitis, 2) and non-IBD (colorectal cancer, 5; breast cancer, 1) patients. We also analyzed the effects of tumor necrosis factor (TNF)-α on murine ADSCs. RESULTS The numbers of stromal vascular fraction (SVF) cells per gram of SAT were 7.72 ± 3.03 × 105 in IBD and 8.51 ± 8.80 × 105 in non-IBD patients (p > 0.05). The proportions of ADSCs in SVF cells were 4.98 ± 2.61% in IBD and 1.02 ± 0.67% in non-IBD patients. The numbers of ADSCs per gram of SAT were 4.16 ± 2.96 × 104 in IBD and 0.88 ± 1.04 × 104 in non-IBD patients. The proportions and numbers of ADSCs were significantly higher in IBD patients than in non-IBD patients. TNF-α significantly facilitated the proliferation and motility of murine ADSCs. CONCLUSION These results showed the potential advantage of freshly isolated autologous ADSCs in IBD patients.

Abstract
Due to their osteogenic germination potential, periosteum-derived osteoprogenitor cells are a potential source for tissue engineering a bone graft that could be used to regenerate skeletal defects. In this study we evaluated if ectopic bone formation could be induced by a construct made of human periosteal cells and a novel scaffold architecture whose mechanical properties are in the range of cancellous bone. Biopsies from human calvarial periosteum were harvested and cells were isolated from the inner cambial layer. Fifty thousand periosteal cells were seeded into the scaffolds measuring 6 × 6 × 2 mm. The cell–scaffold constructs were cultured for a period of 3 weeks prior to implantation into balb C nude mice. Mice were sacrificed and implants were analyzed 6 and 17 weeks postoperatively. Immunohistochemical analysis confirmed the osteoblastic phenotype of the seeded cells. Formation of focal adhesions and stress fibers could be observed in both scaffold architectures. Three-dimensional cell proliferation was observed after 2 weeks of culturing with centripetal growth pattern inside the pore network. The deposition of calcified extracellular matrix was observed after 3 weeks of culturing. In vivo, endochondral bone formation with osteoid production was detectable via von Kossa and Osteocalcin staining after 6 and 17 weeks. Histology and SEM revealed that the entire scaffold/bone grafts were penetrated by a vascular network. This study showed the potential of bone tissue engineering by using human periosteal cells in combination with a novel scaffold technology.

Abstract
A previous study reported that Yi Guan Jian (YGJ) may increase the proliferation and differentiation of hepatic oval cells in a rat liver cirrhosis model. The aim of the present study was to investigate the effect and mechanism of action of YGJ on inducing hepatic differentiation in bone marrow-derived mesenchymal stem cells (BM-MSCs) via stromal-cell derived factor-1 (SDF-1). Murine BM-MSCs were isolated with whole bone marrow adherence, then identified by immunocytochemical staining and flow cytometry. Passage 2 cells were divided into 8 groups and their differentiation was induced by cell factors added to the medium, including hepatocyte growth factor (HGF), SDF-1 and YGJ. Each of the cell factors was used alone and any two or three of them were combined to establish different cell microenvironments in the different treatment groups. Albumin (ALB) was selected as a hepatocellular marker and cytokeratin-18 (CK-18) as a cholangiocellular marker. The protein and mRNA expression levels of ALB and CK-18 were used to determine the differentiation of BM-MSCs using immunocytochemical staining, western blotting and reverse transcription-quantitative polymerase chain reaction on days 7, 14, 21 and 28 during induction. The relative expression levels of ALB and CK-18 resulted in time-dependent increases in the groups supplemented only with HGF, SDF-1 or YGJ. Combination treatment of any two HGF, SDF-1 and YGJ led to a higher expression of ALB and CK-18 compared with only one cell factor treatment. Additionally, when all three were used in a combined treatment the expression levels of ALB and CK-18 occurred at an earlier time and was higher overall. Therefore, the present study suggested that YGJ had an effect on inducing hepatic differentiation in BM-MSCs via SDF-1 and may act in a synergistic manner with HGF and SDF-1.

Abstract
We developed fully opened interconnected porous calcium hydroxyapatite ceramics having two different pore sizes. One has pores with an average size of 150 μm in diameter, an average 40-μm interconnecting pore diameter, and 75% porosity (HA150). The other has pores with an average size of 300 μm in diameter, an average 60–100-μm interconnecting pore diameter, and 75% porosity (HA300). Because of its smaller pore diameter, HA150 has greater mechanical strength than that of HA300. These ceramics were combined with rat marrow mesenchymal cells and cultured for 2 weeks in the presence of dexamethasone. The cultured ceramics were then implanted into subcutaneous sites in syngeneic rats and harvested 2–8 weeks after implantation. All the implants showed bone formation inside the pore areas as evidenced by decalcified histological sections and microcomputed tomography images, which enabled three-dimensional analysis of the newly formed bone and calculation of the bone volume in the implants. The bone volume increased over time. At 8 weeks after implantation, extensive bone volume was detected not only in the surface pore areas but also in the center pore areas of the implants. A high degree of alkaline phosphatase activity with a peak at 2 weeks and a high level of osteocalcin with a gradual increase over time were detected in the implants. The levels of these biochemical parameters were higher in HA150 than in HA300. The results indicate that a combination of HA150 and mesenchymal cells could be used as an excellent bone graft substitute because of its mechanical properties and capability of inducing bone formation.

Abstract
In this article we describe the expansion of in vitro osteogenic capability of human osteoblasts (HOS cells) after sorting by fluorescence-activated cell sorting (FACS) with the osteoblastic marker of human bone alkaline phosphatase (AP) monoclonal antibody. After culturing for 7 days, the HOS cells were incubated with fluorescein isothiocyanate (FITC)-labeled AP monoclonal antibody. The antibody recognized the cells with high AP activity (high AP cells), which were about 76% of the total cells. After the HOS cells were sorted, the high AP cells could be recovered, and almost all of them reacted strongly with the AP antibody. Therefore, we were able to condense the high AP cells about 1.3 times. We further cultured the sorted cells as well as the unsorted control cells. After the initial seeding, the culturing periods for both groups of cells were 20 days. At the end of this period, we measured AP activity per DNA and osteocalcin contents. In contrast to the low condensation ratio of the high AP cells in the sorted fraction, the AP activity and osteocalcin contents were about nine times and four times greater than those of the unsorted cells, respectively. These results demonstrated that using the sorting technique to isolate the high AP cells might be a useful method for applications in bone tissue engineering.

Abstract
Human Mesenchymal Stem Cells, hMSCs, were first named over 25 years ago with the "stem cell" nomenclature derived from the fact that we and others could cause these cells to differentiate into a number of different mesodermal phenotypes in cell culture. The capacity to form skeletal tissue in vitro encouraged the use of hMSCs for the fabrication of tissue engineered skeletal repair tissue with subsequent transplantation to in vivo sites. With the current realization that MSCs are derived from perivascular cells, pericytes, and the immunomodulatory and trophic capabilities of MSCs in both in vitro and in vivo test systems, a complete re-evaluation of the role and functions of MSCs in the body was required. Additionally, the skeleton is a preferred organ for cancer dissemination from various tumor malignancies. To date, most efforts to understand skeletal metastasis have focused on the invasive and digestive capability of disseminated tumor cells (DTCs). The contribution of the target organ-specific microvascular structure influencing extravasation is less well understood. Current targeted cancer therapies are designed to alter not only biological functions in DTCs, but also components of the tumor stroma/microenvironment such as blood vessels. We now have a comprehensive image of the critical role of the host vasculature as an instructive niche for DTCs. The focus of this manuscript is to present the current information about MSC function in situ and to emphasize how these new observations provide insight into understanding the role of the pericyte/MSC in skeletal activities including our new hypothesis for how these cells act as a gatekeeper for metastasis of melanoma into bone. © 2017 Orthopaedic Research Society.

Abstract
The neural crest (NC) arises near the neural tube during embryo development. NC cells migrate throughout the embryo and have potential to differentiate into multiple cell types, such as peripheral nerves, glial, cardiac smooth muscle, endocrine, and pigment cells, and craniofacial bone. In the present study, we induced osteoblast-like cells using whisker follicles obtained from the NC of mice. Hair follicle cells derived from the NC labeled with enhanced green fluorescent protein (EGFP) were collected from protein zero-Cre/floxed-EGFP double transgenic mice and cultured, then treated and cultured in stem cell growth medium. After growth for 14 days, results of flow cytometry analysis showed that 95% of the EGFP-positive (EGFP+) hair follicle cells derived from the NC had proliferated and 76.2% of those expressed mesenchymal stem cells markers, such as platelet-derived growth factor α and stem cell antigen-1, and also showed constitutive expression of Runx2 mRNA. Cells stimulated with bone morphogenetic protein-2 expressed osteocalcin, osterix, and alkaline phosphatase mRNA, resulting in production of mineralized matrices, which were detected by von Kossa and alizarin red staining. Moreover, EGFP+ hair follicle cells consistently expressed macrophage colony-stimulating factor and osteoprotegerin (OPG). Addition of 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3] (10-8 M) to the cultures suppressed OPG expression and induced RANKL production in the cells. Furthermore, multinucleated osteoclasts appeared within 6 days after starting co-cultures of bone marrow cells with EGFP+ cells in the presence of 1,25(OH)2D3 and PGE2. These results suggest that NC-derived hair follicle cells possess a capacity for osteoblastic differentiation and may be useful for developing new bone regenerative medicine therapies.

Abstract
BACKGROUND There is a strong impetus for the development of alternative treatments for bone disease that avoid the complications associated with autografts and allografts. To address this, we previously developed porous apatite-fiber scaffolds (AFSs) which have three-dimensional interconnected pores, and constructed tissue-engineered bone by culturing rat bone marrow cells (RBMCs) using AFSs in a radial-flow bioreactor (RFB). OBJECTIVE To generate additional baseline data for the development of tissue-engineered bone constructed for clinical application using a RFB, we cultured RBMCs using AFSs under static conditions (hereafter, RBMC AFS culture), and monitored RBMC growth and differentiation characteristics in vitro, and two weeks after subcutaneous inoculation into recipient rats. METHODS RBMCs were seeded to AFSs and growth, differentiation and calcification were monitored in vitro and in vivo by histological evaluation using hematoxylin eosin, alkaline phosphatase and alizarin red S stains. RESULTS RBMCs in/on AFSs proliferated and differentiated normally in vitro and in vivo, and calcification was evident two weeks after subcutaneous AFS culture implantation. Histological assays revealed that AFSs and RBMC AFS cultures were biocompatible, and did not induce inflammation or immunological rejection in vivo. CONCLUSIONS These findings suggest that AFSs are a conducive microenvironment for bone regeneration and are well tolerated in vivo. The results provide valuable baseline data for the design of implant studies using tissue-engineered bone constructed by RFB.

Abstract
Background Adipose-derived stem cells (ASCs) are a robust, multipotent cell source. They are easily obtained and hold promise in many regenerative applications. It is generally considered that the function of somatic stem cells declines with age. Although several studies have examined the effects of donor age on proliferation potential and pluripotency of ASCs, the results of these studies were not consistent. Objective This study tested whether the donor age affects the yield of ASCs from adipose tissue, as well as the proliferation and differentiation potentials of ASCs. Methods This study used ASCs obtained from adipose tissues of 260 donors (ages 5–97 years). ASCs were examined for individual differences in proliferation, and adipogenic, osteogenic and chondrogenic differentiation potentials in vitro. Characteristics of ASCs from each donor were evaluated by the principal component analysis (PCA) using their potential parameters. Results Analyses on ASCs demonstrated that adipogenic potentials declined with age, but proliferation, osteogenic and chondrogenic potentials were not correlated with age. Interestingly, in all ASC potentials, including adipogenesis, individual differences were observed. Principal component analysis (PCA) revealed that individual differences became evident in the elderly, and those variations were more prominent in females than in males. Conclusions This study demonstrated age-related changes in the potentials of ASCs and revealed that the individual differences of ASCs become significant in people over 60 years of age (for females over 60, and for males over 80). We believe that it is important to carefully observe ASC potentials in order to achieve effective regenerative medicine treatments using ASCs. ASCs can be isolated from subjects in all ages. Adipogenic potential of ASCs declines with age. Chondrogenic and osteogenic potentials of ASCs are not affected by age. Proliferation and differentiation potentials of ASCs are individually different. Individual difference of ASC potentials becomes significant over 60 years of age.

Abstract
Background We explored the effect of parathyroid hormone (PTH)-induced bone marrow stem cells (BMSCs) complexed with fibrin glue (FG) in the repair of articular cartilage injury in rabbits. Material/Methods Forty-eight rabbits randomized into four groups were subjected to articular surgery (cartilage loss). The PTH and non-PTH intervention groups included transplantation with PTH/BMSC/FG xenogeneic and BMSC/FG xenogeneic complexes, respectively, into the injured area. The injured group contained no transplant while the control group comprised rabbits without any articular injury. Samples were monitored for cartilage repair up to three months post-surgery. Immunohistochemistry as well as real-time fluorescent quantitative PCR and Western blot were used to analyze the expression of type II collagen and aggrecan in the repaired tissue. Results At 12 weeks post-surgery, the loss of articular cartilage in the PTH group was fully repaired by hyaline tissue. Typical cartilage lacunae and intact subchondral bone were found. The boundary separating the surrounding normal cartilage tissue disappeared. The gross and International Cartilage Repair Society (ICRS) histological ranking of the repaired tissue was significantly higher in the PTH intervention group than in the non-PTH intervention and injury groups (p<0.05) without any significant difference compared to the control group (p>0.05). Type II collagen and aggrecan stained positive and the average optical density, relative mRNA expression and protein-integrated optical density in the PTH group were higher than in non-PTH and injured groups (p<0.05) but not significantly different from the control group (p>0.05). Conclusions PTH/BMSC/FG xenogeneic complexes effectively repaired the loss of cartilage in rabbit knee injury.

Abstract
Objectives To assess the structure and extracellular matrix molecule expression of osteogenic cell sheets created via culture in medium with both dexamethasone (Dex) and ascorbic acid phosphate (AscP) compared either Dex or AscP alone. Methods Osteogenic cell sheets were prepared by culturing rat bone marrow stromal cells in a minimal essential medium (MEM), MEM with AscP, MEM with Dex, and MEM with Dex and AscP (Dex/AscP). The cell number and messenger (m)RNA expression were assessed in vitro, and the appearance of the cell sheets was observed after mechanical retrieval using a scraper. β-tricalcium phosphate (β-TCP) was then wrapped with the cell sheets from the four different groups and subcutaneously implanted into rats. Results After mechanical retrieval, the osteogenic cell sheets from the MEM, MEM with AscP, and MEM with Dex groups appeared to be fragmented or incomplete structures. The cell sheets cultured with Dex/AscP remained intact after mechanical retrieval, without any identifiable tears. Culture with Dex/AscP increased the mRNA and protein expression of extracellular matrix proteins and cell number compared with those of the other three groups. More bridging bone formation was observed after transplantation of the β-TCP scaffold wrapped with cell sheets cultured with Dex/AscP, than in the other groups. Conclusions These results suggest that culture with Dex/AscP improves the mechanical integrity of the osteogenic cell sheets, allowing retrieval of the confluent cells in a single cell sheet structure. This method may be beneficial when applied in cases of difficult tissue reconstruction, such as nonunion, bone defects, and osteonecrosis. Cite this article: M. Akahane, T. Shimizu, T. Kira, T.

Abstract
Adipose-derived mesenchymal stem cells (ASCs) have the potential to differentiate into cells of mesodermal origin, such as osteoblasts, adipocytes, myocytes, and chondrocytes, and cryopreservation is currently performed as a routine method for preserving ASCs to safely acquire large numbers of cells. For clinical application of ASCs, serum-free, xeno-free cryopreservation solutions should be used. This study determined the viability and adipo-osteogenic potential of cryopreserved ASCs using four cryopreservation solutions: 10% DMSO, Cell Banker 2 (serum free), Stem Cell Banker (=Cell Banker 3: serum free, xeno free), and TC protector (serum free, xeno free). The viability of the cryopreserved ASCs was over 80% with all cryopreservation solutions. No difference in the adipo-osteogenic potential was found between the cells that did or did not undergo cryopreservation in these cryopreservation solutions. These data suggest that Cell Banker 3 and TC protector are comparable with 10% DMSO and Cell Banker 2 for ASCs, and cryopreserved as well as noncryopreserved ASCs could be applied for regenerative medicine.

Abstract
A bone-like apatite-coated surface that mediates a positive interaction between materials and bone is key to the development of desirable bone substitute materials. To incorporate apatite-coating on poly(L-lactide) (PLLA) surfaces, the effect of the hydrolysis of PLLA surfaces on the formation ability of bone-like apatite was investigated in this study.PLLA films and porous PLLA scaffolds were hydrolyzed for different time periods in alkaline solution and the hydrolyzed PLLA surfaces were characterized with X-ray photoelectron spectroscopy, atomic force microscopy, contact angle, and the measurement of carboxyl density. An apatite coating was formed by mineralizing the hydrolyzed PLLA in simulated body fluids (SBF) for 3 weeks and characterized. The hydrolyzed PLLA surfaces were rich in COOH and OH; the hydrophilicity, surface roughness, and carboxyl density increased with the hydrolysis time. After the incubation in SBF, a bone-like apatite layer with different morphology and composition was formed on the PLLA surfaces. The apatite formation on PLLA surfaces was promoted by the hydrolysis pretreatment and this increases with hydrolysis time. In addition, the compression module of the apatite-coated PLLA scaffolds increased compared with the pure PLLA scaffolds and increased with the hydrolysis time. The hydrolysis pretreatment was important in functionalizing the PLLA surfaces, facilitating subsequent apatite nucleation and apatite growth.

Abstract
In this study, osteoblastic cells were isolated from rat bone marrow and characterized. The cells were cultured on β-TCP granules and the osteoblast/ β-TCP constructs. For this purpose, bone marrow was harvested under sterile conditions. Cell aggregates were broken up by pipetting and a cell suspension was cultured in DMEM/F12. After three days, the cells that adhered to the surface of the flask were cultured in osteoblast medium. When the cells became confluent, they were passaged and cultured in 24-well polystyrene cell culture dishes. Characterization of the osteoblasts, cell proliferation and alkaline phosphatase activity were measured on days 1, 7, 14, 21 and 30. To investigate the cell compatibility of the β-TCP granules, osteoblastic cells were cultured on β-TCP granules and a polystyrene cell culture dish (control group). Cell proliferation and alkaline phosphatase (ALP) activity were measured on days 1, 7, 14, 21 and 30 in both groups. Cell growth significantly increased at each time point, but on day 30 a decrease was observed. The ALP activity also increased at each time point and also decreased on day 30. This study may be regarded as the first step leading to a therapy for various bone defects.
