Abstract
Bone healing deficiencies are challenging for orthopedic practice. The use of stem cells with scaffolds to treat bone tissue losses currently is popular for promoting regeneration of tissue. Programmable cells of monocytic origin (PCMO) may differentiate into three germ layers and may be a promising alternative treatment due to their stem cell-like properties. Parathyroid hormone (PTH) participates in bone metabolism. Intermittent administration of PTH promotes osteogenic activity of mesenchymal stem cdells (MSC). We investigated the osteogenic effects of continuous and intermittent administration of PTH on PCMO. Mononuclear cells were harvested from the peripheral blood of healthy donors. Isolated cells were cultured for six days in a de-differentiation medium. Indirect immunocytochemistry using anti-CD14, anti-CD45 and anti-CD90 primary antibodies, as well as electron microscopy were used to detect PCMO. PCMO then were cultured in an osteogenic differentiation medium supplemented with continuous or intermittent 50 ng/ml PTH. The PTH-free control group (CG), intermittent PTH treated group (IPG) and continuous PTH treated group (CPG) were cultured and assessed for their differentiation into osteogenic lineage cells by indirect immunocytochemistry using anti-collagen I, anti-osteonectin and anti-osteocalcin primary antibodies. Osteoblast-like cells obtained by continuous or intermittent PTH administration exhibited increased levels of collagen I, osteonectin and osteocalcin immunoreactivity. We found that continuous and intermittent PTH administration to PCMO enhanced their differentiation to osteogenic lineage cells and increased osteoblastic activity.

Differentiation and proliferation potencies of human bone tissue-derived mesenchymal stromal cells (hBT-MSCs) after long-term cryopreservation -Comparison among cells stored for 1, 5, 10, 15, and 20 years. Regen Ther 2021; 18:363-371. [PMID: 34632009 PMCID: PMC8473671 DOI: 10.1016/j.reth.2020.01.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2019] [Revised: 10/12/2019] [Accepted: 01/26/2020] [Indexed: 12/02/2022] Open
Abstract
INTRODUCTION We investigated bone differentiation and proliferation potencies of human bone tissue-derived mesenchymal stromal cells (hBT-MSCs) after long-term cryopreservation. We determined the presence of any morphological and characteristic changes due to freezing to identify issues that need to be solved for future clinical applications. SUBJECTS AND METHODS A total of 15 samples of hBT-MSCs that had been cryopreserved for different lengths of time, ranging from one year to 20 years (n = 3 each), were thawed and recultivated after being collected from excess iliac cancellous bone specimens of patients who underwent secondary alveolar bone grafting for cleft lip and palate in our department. We determined viability by observing calcein/EthD-stained cells under a confocal microscope, and the cell proliferation experiment was performed for one week using the Water Soluble Tetrazolium salts (WST) assay method. A confocal microscope was also used to identify any excessively accumulated senescence-associated growth factor SA-βgal. Differentiation potency was assessed in the following three groups: bone differentiation, adipocyte differentiation, and nondifferentiation induction. We examined bone/adipocyte differentiation potencies using Alizarin Red staining, Ca quantitation, and Oil Red staining after continuously culturing cells for four weeks. RESULTS Viability test results indicated that the proportion of viable cells decreased as the number of years of cryopreservation increased. The cell proliferation experiment showed that cells cryopreserved for a shorter duration multiplied exponentially. In the aging test, cells cryopreserved for ≥5 years showed similar positive reactions independent of the number of years of cryopreservation. In the cell proliferation test, there was no statistically significant difference between the years of cryopreserving. We compared bone differentiation and adipocyte differentiation ability with the non-induction group, and the induction group was confirmed to have a statistical advantage. However, there was no significant difference in the induction group pertaining to different ages. CONCLUSIONS Samples cryopreserved for 20 years remained competent in bone and adipocyte differentiation. However, their differentiation direction tended to skew to either bone or adipocyte differentiation. Our results suggest that freezing does not accelerate aging, and samples cryopreserved for a long time are useful in future clinical applications.

Abstract
Titanium is considered to be a metal material with the best biological safety. Studies have proved that the titanium implanted in the bone continuously releases titanium particles (Ti particles), significantly increasing the total titanium content in human body. Generally, Ti particles are released slowly without causing a systemic immune response. However, the continuous increased local concentration may result in damage to the intraepithelial homeostasis, aggravation of inflammatory reaction in the surrounding tissues, bone resorption and implant detachment. They also migrate with blood flow and aggregate in the distal organ. The release of Ti particles is affected by the score of the implant surface structure, microenvironment wear and corrosion, medical operation wear, and so on, but the specific mechanism is not clear. Thus, it difficult to prevent the release completely. This paper reviews the causes of the Ti particles formation, the damage to the surrounding tissue, and its mechanism, in particular, methods for reducing the release and toxicity of the Ti particles.

Abstract
Musculoskeletal diseases involving loss of tissue usually require management with bone grafts, among which autografts are still the gold standard. To overcome autograft disadvantages, the development of new scaffolds is constantly increasing, as well as the number of in vivo studies evaluating their osteoinductivity in ectopic sites. The aim of the present systematic review is to evaluate the last 10 years of osteoinduction in vivo studies. The review is focused on: (a) which type of animal model is most suitable for osteoinduction evaluation; (b) what are the most used types of scaffolds; (c) what kind of post-explant evaluation is most used. Through three websites (www.pubmed.com, www.webofknowledge.com and www.embase.com), 77 in vivo studies were included. Fifty-eight studies were conducted in small animal models (rodents) and 19 in animals of medium or large size (rabbits, dogs, goats, sheep, and minipigs). Despite the difficulty in establishing the most suitable animal model for osteoinductivity studies, small animals (in particular mice) are the most utilized. Intramuscular implantation is more frequent than subcutis, especially in large animals, and synthetic scaffolds (especially CaP ceramics) are preferred than natural ones, also in combination with cells and growth factors. Paraffin histology and histomorphometric evaluations are usually employed for postimplantation analyses.

Abstract
PURPOSE Umbilical cord blood-derived platelet-rich plasma (UCB-PRP) containing growth factors has attracted attention as a biomaterial useful for regenerative medicine. The osteoblastic differentiation of umbilical cord-derived mesenchymal stromal cells (UC-MSCs) can be induced by UCB-PRP. MATERIALS AND METHODS Nine samples of UC and UCB were used to conduct an in vitro study that determined the contents of three growth factors (i.e., platelet-derived growth factor, transforming growth factor β-1, and vascular endothelial growth factor) and that examined, by staining with Alizarin red, their ability to induce the osteoblastic differentiation of UC-MSCs at the baseline, 3 months, and 3 years of cryopreservation. RESULTS The contents of growth factors in cryopreserved UCB-PRP were markedly elevated compared to those found in UCB at baseline. The samples of UCB that were added with cryopreserved UCB-PRP and those with bone morphogenetic protein-2 were stained granularly with Alizarin red, thus indicating the presence of calcium. The samples of UCB that were not added with UCB-PRP were not stained with Alizarin red. The above-mentioned contents and ability were maintained at 3 years of cryopreservation. Cryopreserved UCB-PRP possibly and advantageously induced the osteoblastic differentiation of UC-MSCs. CONCLUSION The potential clinical application of cryopreserved UCB-PRP to regenerative medicine was suggested.

Abstract
Fetal bovine serum (FBS) is the most commonly used supplement for ex vivo expansion of human mesenchymal stem cells (hMSCs) for bone tissue engineering applications. However, from a clinical standpoint, it is important to substitute animal-derived products according to current good manufacturing practice (cGMP) guidelines. Humanized alternatives to FBS include three categories of products: human serum (HS), human platelet derivatives (HPDs)-including platelet lysate (PL) or platelet releasate (PR), produced by freeze/thawing or chemical activation of platelet concentrates, respectively, and chemically defined media (serum-free) (CDM). In this systematic literature review, the in vitro and in vivo osteogenic potential of hMSCs expanded in humanized (HS-, HPD-, or CDM-supplemented) media versus hMSCs expanded in FBS-supplemented media, was compared. In addition, PL and PR were compared in terms of their growth factor (GF)/cytokine-content and cell-culture efficacy. When using either 10-20% autologous or pooled HS, 3-10% pooled HPDs or CDM supplemented with GFs, in comparison with 10-20% FBS, a majority of studies reported similar or superior in vitro proliferation and osteogenic differentiation, and in vivo bone formation in ectopic or orthotopic rodent models. Moreover, a trend for higher GF content was observed in PL versus PR, although evidence for cell culture efficacy is limited. In summary, humanized supplements seem at least equally effective as FBS for hMSC expansion and osteogenic differentiation. Although pooled HPDs appear to be the most favorable supplement for large-scale hMSC expansion, further efforts are needed to standardize the preparation and composition of these products in compliance with cGMP standards.

Abstract
AIM To analyze the concentration-dependent effects of autologous serum (AS) and fetal bovine serum (FBS) on human corneal epithelial cell (HCEC) viability, migration and proliferation. METHODS AS was prepared from 13 patients with non-healing epithelial defects Dulbecco's modified eagle medium/Ham's F12 (DMEM/F12) with 5% FBS, 0.5% dimethyl sulphoxide (DMSO), 10 ng/mL human epidermal growth factor, 1% insulin-transferrin-selenium, then were incubated in serum media: DMEM/F12 supplemented by 5%, 10%, 15% or 30% AS or FBS. HCEC viability was analyzed using cell proliferation kit XTT, migration using a wound healing assay, proliferation by the cell proliferation enzyme-linked immunosorbent assay (ELISA) BrdU kit. Statistical analysis was performed using the generalized linear model, the values at 30% AS or 30% FBS were used as the baselines. RESULTS HCEC viability was the highest at 30% AS or 15% FBS and the lowest at 10% AS or 30% FBS application. HCEC migration was the quickest through 30% AS or 30% FBS and the slowest through 5% AS or 5% FBS concentrations. Proliferation was the most increased through 15% AS or 5% FBS and the least increased through 30% AS or 30% FBS concentrations. HCEC viability at 10% and 15% AS was significantly worse (P=0.001, P=0.023) compared to baseline and significantly better at 15% FBS (P=0.003) concentrations. HCEC migration was significantly worse (P≤0.007) and HCEC proliferation significantly better (P<0.001) in all concentration groups compared to baseline. CONCLUSION For the best viability of HCEC 30% AS or 15% FBS, for HCEC migration 30% AS or 30% FBS, for proliferation 15% AS or 5% FBS should be used. Therefore, we suggest the use of 30% AS in clinical practice.

Abstract
Bone tissue engineering is in the process of making the shift from bench to bed. Organ as a cell source is important for tissue engineering. The appropriate cells should be harvested without invasiveness and ethical problems. The authors focused on mandibular cortex bone fragments removed in sagittal split ramus osteotomy as a cell source for bone tissue engineering. These bone fragments were discarded after surgery until now. Bone marrow stromal cells (BMSCs) were harvested from inside of bone fragments, which is an endosteal region. Endosteal region is known to be a hematopoietic stem cell niche and harbors osteoblasts, preosteoblasts, and mesenchymal stem cells (MSCs). Bone marrow stromal cells could be cultured easily, and grew rapidly in vitro under ordinary serum-supplemented culture condition. The expression pattern of surface markers of BMSCs was the same as that of MSCs. Bone marrow stromal cells could differentiated into multiple mesenchymal lineages (osteoblasts, adipocytes, chondrocytes, and smooth muscle cells). These results indicated the existence of MSCs in BMSCs. The osteoblastic characters of BMSCs were examined more closely. Bone marrow stromal cells showed a high alkaline phosphatase activity, and expressed osteoblastic markers (PTHr, bone sialoprotein, Type I collagen, Rnut-related transcription factor 2, and osteocalcin). In transplantation experiments, BMSCs generated ectopic bone tissues on the border of hydroxyapatite scaffold without osteogenic differentiation-inducing agents such as dexamethasone (Dex) or bone morphogenetic protein. The results of this study suggest that mandibular cortex bone fragments removed in sagittal split ramus osteotomy are a good cell source for bone tissue engineering.

Abstract
For decades, researchers have been developing a range of promising strategies in bone tissue engineering with the aim of producing a significant clinical benefit over existing therapies. However, a major problem concerns the traditional use of xenogeneic substances for the expansion of cells, which complicates direct clinical transfer. The study's aim was to establish a totally autologous sheep model as a basis for further preclinical studies and future clinical application. Ovine mesenchymal stromal cells (MSC) were cultivated in different concentrations (0%, 2%, 5%, 10%, and 25%) of either autologous serum (AS) or fetal calf serum (FCS). With an increase of serum concentration, enhanced metabolic activity and proliferation could be observed. There were minor differences between MSC cultivated in AS or FCS, comparing gene and protein expression of osteogenic and stem cell markers, morphology, and osteogenic differentiation. MSC implanted subcutaneously in the sheep model, together with a nanostructured bone substitute, either in stable block or moldable putty form, induced similar vascularization and remodeling of the bone substitute irrespective of cultivation of MSC in AS or FCS and osteogenic differentiation. The bone substitute in block form together with MSC proved particularly advantageous in the induction of ectopic bone formation compared to the cell-free control and putty form. It could be demonstrated that AS is suitable for replacement of FCS for cultivation of ovine MSC for bone tissue engineering purposes. Substantial progress has been made in the development of a strictly xenogeneic-free preclinical animal model to bring future clinical application of bone tissue engineering strategies within reach.

Abstract
The purpose of this study was to assess fetal bovine acellular dermal matrix as a scaffold for supporting the differentiation of bone marrow mesenchymal stem cells into neural cells following induction with neural differentiation medium. We performed long-term, continuous observation of cell morphology, growth, differentiation, and neuronal development using several microscopy techniques in conjunction with immunohistochemistry. We examined specific neuronal proteins and Nissl bodies involved in the differentiation process in order to determine the neuronal differentiation of bone marrow mesenchymal stem cells. The results show that bone marrow mesenchymal stem cells that differentiate on fetal bovine acellular dermal matrix display neuronal morphology with unipolar and bi/multipolar neurite elongations that express neuronal-specific proteins, including βIII tubulin. The bone marrow mesenchymal stem cells grown on fetal bovine acellular dermal matrix and induced for long periods of time with neural differentiation medium differentiated into a multilayered neural network-like structure with long nerve fibers that was composed of several parallel microfibers and neuronal cells, forming a complete neural circuit with dendrite-dendrite to axon-dendrite to dendrite-axon synapses. In addition, growth cones with filopodia were observed using scanning electron microscopy. Paraffin sectioning showed differentiated bone marrow mesenchymal stem cells with the typical features of neuronal phenotype, such as a large, round nucleus and a cytoplasm full of Nissl bodies. The data suggest that the biological scaffold fetal bovine acellular dermal matrix is capable of supporting human bone marrow mesenchymal stem cell differentiation into functional neurons and the subsequent formation of tissue engineered nerve.

Abstract
This study examined the potential for osteogenesis via regenerative medicine using autologous tissues (umbilical cord (UC) and umbilical cord blood (UCB)) in nude mice. The study was designed to provide the three elements required for regenerative medicine (cell, scaffold, and growth factor) and autoserum for culture by means of autologous tissues. Mesenchymal stromal cells were obtained from UC (UC-MSCs). Fibrin, platelet-rich-plasma, and autoserum were obtained from UCB as scaffold, growth factor and serum for culture respectively. UC-MSCs were obtained from Wharton jelly and cultured with UCB-derived fibrin (UCB-fibrin) for 3-4 weeks to induce their differentiation into osteoblasts. They were implanted subcutaneously into the dorsum of male nude mice for 6 weeks prior to undergoing assessment. The assessments performed were haematoxylin and eosin, and alizarin red staining, immunohistochemical staining of human mitochondria, scanning electron microscopy, scanning electron microscopy with energy dispersive X-ray spectrometry and real-time reverse transcriptase-polymerase chain reaction to assess the expressions of osteoblast markers. Consequently, the differentiation of UC-MSCs into osteoblasts and the production of hydroxyapatite were verified. This study suggested the possible formation of bone tissue using biomedical materials obtained from UC and UCB.
