Abstract
In the 21st century, significant progress has been made in repairing damaged materials through material engineering. However, the creation of large-scale artificial materials still faces a major challenge in achieving proper vascularization. To address this issue, researchers have turned to biomaterials and three-dimensional (3D) bioprinting techniques, which allow for the combination of multiple biomaterials with improved mechanical and biological properties that mimic natural materials. Hydrogels, known for their ability to support living cells and biological components, have played a crucial role in this research. Among the recent developments, 3D bioprinting has emerged as a promising tool for constructing hybrid scaffolds. However, there are several challenges in the field of bioprinting, including the need for nanoscale biomimicry, the formulation of hydrogel blends, and the ongoing complexity of vascularizing biomaterials, which requires further research. On a positive note, 3D bioprinting offers a solution to the vascularization problem due to its precise spatial control, scalability, and reproducibility compared with traditional fabrication methods. This paper aims at examining the recent advancements in 3D bioprinting technology for creating blood vessels, vasculature, and vascularized materials. It provides a comprehensive overview of the progress made and discusses the limitations and challenges faced in current 3D bioprinting of vascularized tissues. In addition, the paper highlights the future research directions focusing on the development of 3D bioprinting techniques and bioinks for creating functional materials.

Abstract
Human mesenchymal stem cells (hMSCs) are multipotent cells and an attractive therapeutic agent in regenerative medicine and intensive clinical research. Despite the great potential, the limitation that needs to be overcome is the necessity of ex vivo expansion because of insufficient number of hMSCs presented within adult organs and the high doses required for a transplantation. As a result, numerous research studies aim to provide novel expansion methods in order to achieve appropriate numbers of cells with preserved therapeutic quality. Bioreactor-based cell expansion provide high-level production of hMSCs in accordance with good manufacturing practice (GMP) and quality standards. This review summarizes current knowledge about the hMSCs manufacturing platforms with a main focus to the application of bioreactors for large-scale production of GMP-grade hMSCs.

Abstract
Mesenchymal stem/stromal cells (MSCs) are undifferentiated cells with multilinear potential, known for their immunomodulatory and regenerative properties. Although the scientific community is working to improve their application, concerns limit their use to repair tissues following neurological damage. One of these obstacles is represented by the use of culture media supplemented with fetal bovine serum (FBS), which, due to its xenogenic nature and the risk of contamination, has increased scientific, ethical and safety problems. Therefore, the use of serum-free media could improve MSC culture methods, avoiding infectious and immunogenic transmission problems as well as MSC bioprocesses, without the use of animal components. The purpose of our review is to provide an overview of experimental studies that demonstrate that serum-free cultures, along with the supplementation of growth factors or chemicals, can lead to a more defined and controlled environment, enhancing the proliferation and neuronal differentiation of MSCs.

Effects of Different Basal Cell Culture Media upon the Osteogenic Response of hMSCs Evaluated by 99mTc-HDP Labeling. Int J Mol Sci 2022; 23:ijms23116288.

Abstract
The osteogenic differentiation of mesenchymal stem cells is now a standard procedure in modern bone tissue engineering. As this is a promising field for future clinical applications, many cell culture media exist to promote osteogenic differentiation. Prior to differentiation, cells must be expanded to obtain sufficient numbers for experiments. Little evidence is available regarding the optimal media combination for expansion and differentiation to maximize the osteogenic response. Therefore, human BM-MSCs (n = 6) were expanded in parallel in DMEM (Dulbecco’s Modified Eagle Medium) LG (Low Glucose) and α-MEM (Minimum Essential Media alpha-modification), followed by simultaneous monolayer differentiation toward the osteogenic lineage in: 1. DMEM LG (Low Glucose), 2. DMEM HG (High Glucose), 3. α-MEM, 4. “Bernese medium”, and 5. “Verfaillie medium”, with a corresponding negative control (total 20 groups). As a marker for osteogenic differentiation, hydroxyapatite was accessed using radioactive 99mTc-HDP labeling and quantitative alizarin red staining. The results indicate that all media except “Bernese medium” are suitable for osteogenic differentiation, while there was evidence that DMEM LG is partly superior when used for expansion and differentiation of BM-hMSCs. Using “Verfaillie medium” after DMEM LG expansion led to the highest grade of osteogenic differentiation. Nevertheless, the difference was not significant. Therefore, we recommend using DMEM LG for robust osteogenic differentiation, as it is highly suitable for that purpose, economical compared to other media, and requires little preparation time.

Umbilical Cord-Derived Mesenchymal Stem Cells Are Able to Use bFGF Treatment and Represent a Superb Tool for Immunosuppressive Clinical Applications. Int J Mol Sci 2020; 21:ijms21155366.

Abstract
Mesenchymal stem cells (MSCs) have become a promising tool in cellular therapy for restoring immune system haemostasis; however, the success of clinical trials has been impaired by the lack of standardized manufacturing processes. This study aims to determine the suitability of source tissues and culture media for the production of MSC-based advanced therapy medicinal products (ATMPs) and to define parameters to extend the set of release criteria. MSCs were isolated from umbilical cord (UC), bone marrow and lipoaspirate and expanded in three different culture media. MSC phenotype, proliferation capacity and immunosuppressive parameters were evaluated in normal MSCs compared to primed MSCs treated with cytokines mimicking an inflammatory environment. Compared to bone marrow and lipoaspirate, UC-derived MSCs (UC-MSCs) showed the highest proliferative capacity, which was further enhanced by media supplemented with bFGF, while the cells maintained their immunosuppressive characteristics. Moreover, UC-MSCs expanded in the bFGF-enriched medium were the least sensitive to undesirable priming-induced changes in the MSC phenotype. Surface markers and secreted factors were identified to reflect the cell response to inflammatory priming and to be variable among MSCs from different source tissues. This study demonstrates that UC is a favorable cell source for manufacturing MSC-based ATMPs for immunosuppressive applications. UC-MSCs are able to use the bFGF-enriched medium for higher cell yields without the impairment of immunosuppressive parameters and undesirable phenotype changes after inflammatory preconditioning of MSCs before transplantation. Additionally, immunosuppressive parameters were identified to help finding predictors of clinically efficient MSCs in the following clinical trials.

Abstract
We have evaluated the capability of a collagen/poly glycolic acid (PGA) scaffold in regeneration of a calvarial bone defects in rabbits. 4 bone critical size defects (CSD) were created in the calvarial bone of each rabbit. The following 4 treatment modalities were tested (1) a collagen/PGA scaffold (0.52% w/w); (2) the collagen/PGA scaffold (0.52% w/w) seeded with adipose-derived mesenchymal stem cells (AD-MSCs, 1 × 106 cells per each defect); (3) AD-MSCs (1 × 106 cells) no scaffold material, and (4) blank control. The rabbits were then divided into 3 random groups (of 5) and the treatment outcomes were evaluated at 4, 8 and 12 weeks. New bone formation was histologically assessed. Experimental groups were analyzed by CT scan and real-time PCR. Histological analysis of bone defects treated with collagen/PGA alone exhibited significant fibrous connective tissue formation at the 12 weeks of treatments (P ≤ 0.05). There was no significant difference between collagen/PGA alone and collagen/PGA + AD-MSCs groups. The results were confirmed by CT scan data showing healing percentages of 34.20% for the collage/PGA group alone as compared to the control group and no difference with collagen/PGA containing AD-MSCs (1 × 106 cells). RT-PCR analysis also indicated no significant differences between collagen/PGA and collagen/PGA + AD-MSC groups, although both scaffold containing groups significantly express ALP and SIO rather than groups without scaffolds. Although there was no significant difference between the scaffolds containing cells with non-cellular scaffolds, our results indicated that the Collagen/PGA scaffold itself had a significant effect on wound healing as compared to the control group. Therefore, the collagen/PGA scaffold seems to be a promising candidate for research in bone regeneration.

Abstract
Pancreatic ductal adenocarcinoma (PDA) has poor therapeutic options. Recent patient studies indicate that cholesterol-lowering statins have anti-tumor capacities. We examined several established and primary PDA and normal cell lines as well as PDA patient tissues (n = 68). We found that simvastatin inhibited viability, stemness, tumor growth and metastasis and that it enhanced the efficacy of gemcitabine. These changes were associated with modulation of Shh-related gene expression. Overexpression of Shh prevented the anti-cancer effect of simvastatin, and inhibition of Shh mimicked the simvastatin effect. In PDA tissues, expression levels of Shh, downstream mediators of Shh and progression markers, namely, cMet, CxCR4 and Vimentin, were lower when patients were prescribed statin medication prior to surgery. These results suggested that statins are cost effective and well-tolerated drugs for prevention and co-treatment of PDA.

Abstract
An avenue of tremendous interest and need in health care encompasses the regeneration of bone and cartilage. Over the years, numerous tissue engineering strategies have contributed substantial progress toward the realization of clinically relevant therapies. Cell and tissue culture protocols, however, show many variations that make experimental results among different publications challenging to compare. This collection surveys prevalent cell sources, soluble factors, culture medium formulations, environmental factors, and genetic modification approaches in the literature. The intent of consolidating this information is to provide a starting resource for scientists considering how to optimize the parameters for cell differentiation and tissue culture procedures within the context of bone and cartilage tissue engineering.

Abstract
Mesenchymal stem cells (MSC) exhibit a high self-renewal capacity, multilineage differentiation potential and immunomodulatory properties. This set of exceptional features makes them an attractive tool for research and clinical application. However, MSC are far from being a uniform cell type, which makes standardization difficult. The exact properties of human MSC (hMSC) can vary greatly depending on multiple parameters including tissue source, isolation method and medium composition. In this review we address the most important influence factors. We highlight variations in the differentiation potential of MSC from different tissue sources. Furthermore, we compare enzymatic isolation strategies with explants cultures focusing on adipose tissue and umbilical cords as two relevant examples. Additionally, we address effects of medium composition and serum supplementation on MSC expansion and differentiation. The lack of standardized methods for hMSC isolation and cultivation mandates careful evaluation of different protocols regarding efficiency and cell quality. MSC characterization based on a set of minimal criteria defined by the International Society for Cellular Therapy is a widely accepted practice, and additional testing for MSC functionality can provide valuable supplementary information. The MSC secretome has been identified as an important signaling mechanism to affect other cells. In this context, extracellular vesicles (EVs) are attracting increasing interest. The thorough characterization of MSC-derived EVs and their interaction with target cells is a crucial step toward a more complete understanding of MSC-derived EV functionality. Here, we focus on flow cytometric approaches to characterize free as well as cell bound EVs and address potential differences in the bioactivity of EVs derived from stem cells from different sources. © 2017 International Society for Advancement of Cytometry.

Abstract
Liver disease is a serious problem affecting millions of people with continually increasing prevalence. Stem cell therapy has become a promising treatment for liver dysfunction. We previously reported on human minor salivary gland mesenchymal stem cells (hMSGMSCs), which are highly self-renewable with multi-potent differentiation capability. In this study, keratinocyte-like cells with self-regeneration and hepatic differentiation potential were isolated and characterized, and named human minor salivary gland epithelial progenitor cells (hMSG-EpiPCs). hMSG-EpiPCs were easily obtained via minor intraoral incision; they expressed epithelial progenitor/stem cell and other tissue stem cell markers such as CD29, CD49f, cytokeratins, ABCG2, PLET-1, salivary epithelial cell markers CD44 and CD166, and the Wnt target related gene LGR5 and LGR6. The cells were induced into functional hepatocytes in vitro which expressed liver-associated markers ALB, CYP3A4, AAT, and CK18. Upon transplantation in vivo, they ameliorated severe acute liver damage in SCID mice caused by carbon tetrachloride (CCl4) injection. In a two-thirds partial hepatectomy mouse model, the transplanted cells survived at least 4 weeks and exhibited hepatic potential. These findings demonstrate that hMSG-EpiPCs have potential as a cellular therapy basis for hepatic diseases, physiological and toxicology studies and regenerative medicine.

Abstract
BACKGROUND Mesenchymal stromal cells (MSCs) are currently being evaluated in numerous pre-clinical and clinical cell-based therapy studies. Furthermore, there is an increasing interest in exploring alternative uses of these cells in disease modelling, pharmaceutical screening, and regenerative medicine by applying reprogramming technologies. However, the limited availability of MSCs from various sources restricts their use. Term amniotic fluid has been proposed as an alternative source of MSCs. Previously, only low volumes of term fluid and its cellular constituents have been collected, and current knowledge of the MSCs derived from this fluid is limited. In this study, we collected amniotic fluid at term using a novel collection system and evaluated amniotic fluid MSC content and their characteristics, including their feasibility to undergo cellular reprogramming. METHODS Amniotic fluid was collected at term caesarean section deliveries using a closed catheter-based system. Following fluid processing, amniotic fluid was assessed for cellularity, MSC frequency, in-vitro proliferation, surface phenotype, differentiation, and gene expression characteristics. Cells were also reprogrammed to the pluripotent stem cell state and differentiated towards neural and haematopoietic lineages. RESULTS The average volume of term amniotic fluid collected was approximately 0.4 litres per donor, containing an average of 7 million viable mononuclear cells per litre, and a CFU-F content of 15 per 100,000 MNCs. Expanded CFU-F cultures showed similar surface phenotype, differentiation potential, and gene expression characteristics to MSCs isolated from traditional sources, and showed extensive expansion potential and rapid doubling times. Given the high proliferation rates of these neonatal source cells, we assessed them in a reprogramming application, where the derived induced pluripotent stem cells showed multigerm layer lineage differentiation potential. CONCLUSIONS The potentially large donor base from caesarean section deliveries, the high yield of term amniotic fluid MSCs obtainable, the properties of the MSCs identified, and the suitability of the cells to be reprogrammed into the pluripotent state demonstrated these cells to be a promising and plentiful resource for further evaluation in bio-banking, cell therapy, disease modelling, and regenerative medicine applications.

Abstract
Pancreatic ductal adenocarcinoma (PDA) is one of the most aggressive malignancies and has poor therapeutic options. We evaluated improved oncolytic adenoviruses (OAds), in which the adenoviral gene E1B19K was deleted or a TRAIL transgene was inserted. Bone marrow mesenchymal stromal cells (MSCs) served as carriers for protected and tumor-specific virus transfers. The infection competence, tumor migration, and oncolysis were measured in cancer stem cell (CSC) models of primary and established tumor cells and in tumor xenografts. All OAds infected and lysed CSCs and prevented colony formation. MSCs migrated into PDA spheroids without impaired homing capacity. Xenotransplantation of non-infected PDA cells mixed with infected tumor cells strongly reduced the tumor volume and the expression of the proliferation marker Ki67 along with a necrotic morphology. Adenoviral capsid protein was detected in tumor xenograft tissue after intravenous injection of infected MSCs, but not in normal tissue, implying tumor-specific migration. Likewise, direct in vivo treatment correlated with a strongly reduced tumor volume, lower expression of Ki67 and CD24, and enhanced activity of caspase 3. These data demonstrate that the improved OAds induced efficient oncolysis with the OAd-TRAIL as most promising candidate for future clinical application.

Abstract
The cell therapy industry is a fast-growing industry targeted toward a myriad of clinical indications. As the cell therapy industry matures and clinical trials hit their pivotal Phase 3 studies, there will be a significant need for scale-up, process validation, and critical raw material quality assurance. Part of the well discussed challenges of upscaling manufacturing processes there is a less discussed issue relating to the availability of raw materials in the needed quality and quantities. The FDA recently noted that over 80% of the 66 investigational new drug (IND) applications for mesenchymal stem cell (MSC) products analyzed described the use of FBS during manufacturing. Accumulated data from the past years show an acceleration in serum consumption by at least 10%-15% annually, which suggests that the global demand for serum may soon exceed the supply. Ongoing concerns of safety issues due to risks of various pathogen contaminations, as well as issues related to the aforementioned serum variability that can affect final product reproducibility, are strong motivators to search for serum substitutes or serum-free media. it is important to note that there are no accepted definitions for most of these terms which leads to misleading's and misunderstandings, where the same term might be defined differently by different vendors, manufacturer, and users. It is the drug developer's responsibility to clarify what the supplied labels mean and to identify the correct questions and audits to ensure quality. The paper reviews the available serum replacements, main components, basic strategies for replacement of serum and suggests definitions.

Abstract
BACKGROUND AIMS Mesenchymal stromal cells (MSCs) are being investigated as potential cell therapies for many different indications. Current methods of production rely on traditional monolayer culture on tissue-culture plastic, usually with the use of serum-supplemented growth media. However, the monolayer culturing system has scale-up limitations and may not meet the projected hundreds of billions to trillions batches of cells needed for therapy. Furthermore, serum-free medium offers several advantages over serum-supplemented medium, which may have supply and contaminant issues, leading to many serum-free medium formulations being developed. METHODS We cultured seven MSC lines in six different serum-free media and compared their growth between monolayer and microcarrier culture. RESULTS We show that (i) expansion levels of MSCs in serum-free monolayer cultures may not correlate with expansion in serum-containing media; (ii) optimal culture conditions (serum-free media for monolayer or microcarrier culture) differ for each cell line; (iii) growth in static microcarrier culture does not correlate with growth in stirred spinner culture; (iv) and that early cell attachment and spreading onto microcarriers does not necessarily predict efficiency of cell expansion in agitated microcarrier culture. CONCLUSIONS Current serum-free media developed for monolayer cultures of MSCs may not support MSC proliferation in microcarrier cultures. Further optimization in medium composition will be required for microcarrier suspension culture for each cell line.

Abstract
In a previous study, we established a prenatal surgical approach and transplanted mesenchymal stem cells (MSCs) into the fetal rat spinal column to treat neural tube defects (NTDs). We found that the transplanted MSCs survived and differentiated into neural lineage cells. Various cytokines and extracellular signaling systems in the spinal cord niche play an important role in cell differentiation. In this study, we observed the differentiation of transplanted MSCs in different spinal cord niches and further observed the expression of neurotrophic factors and growth factors in the spinal cord at different developmental stages to explore the mechanism of MSC differentiation in different spinal cord niches. The results showed that transplanted MSCs expressed markers of neural precursor cells (nestin), neurogliocytes (GFAP), and neurons (β-tubulin). The percentages of GFP(+)/nestin(+) double-positive cells in transplanted MSCs in E16, P1, and P21 rats were 18.31%, 12.18%, and 5.06%, respectively. The percentages of GFP(+)/GFAP(+) double-positive cells in E16, P1, and P21 rats were 32.01%, 15.35%, and 12.56%, respectively. The percentages of GFP(+)/β-tubulin(+) double-positive cells in E16, P1, and P21 were 11.76%, 7.62%, and 4.88%, respectively. The differentiation rates of MSCs in embryonic spinal cords were significantly higher than in postnatal spinal cords (p < 0.05). We found that the transplanted MSCs expressed synapsin-1 at different developmental stages. After MSC transplantation, we observed that neurotrophic factor-3 (NT-3), fibroblast growth factor-2 (FGF-2), FGF-8, transforming growth factor-α (TGF-α), vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF) significantly increased in the MSC transplantation group compared with the blank injection group. Furthermore, FGF-2 and VEGF expression were positively correlated with the number of surviving MSCs. In addition, we found that the expression of brain-derived neurotrophic factor (BDNF), NT-3, FGF-8, TGF-β, epidermal growth factor (EGF), and insulin-like growth factor (IGF) decreased with age, and the expression of FGF-2, FGF-10, FGF-20, TGF-α, and PDGF increased with age. Our data suggest that the embryonic spinal cord niche is more conducive to MSC differentiation after transplantation.

Abstract
Numerous scientific studies and clinical trials are carried out each year exploring the use of mesenchymal stromal cells in regenerative medicine and tissue engineering. However, the effective and reliable expansion of this very important cell type remains a challenge. In this study the importance of cell‐to‐cell contact during expansion has been explored on the proliferation and differentiation potential of the produced cells. Cells were cultured up to passage 5 under conditions where cell‐to‐cell contact was either probable (40–70% confluence; see supporting information, Protocol A) or where it was unlikely (10–50% confluence; see supporting information, Protocol B). The effect of the two different conditions on expansion efficiency; proliferation rate and tri‐lineage differentiation potential was assessed. Differences in immunophenotype, cell size and senescence were also investigated. Protocol B cultures expanded twice as fast as those cultured with Protocol A. In passage 5 experiments low confluence expanded cells displayed a 10% higher overall proliferation rate, and produced 23% more cells in growth, 12% more in osteogenic, 77% more in adipogenic, but 27% less in chondrogenic medium. Differentiation potential wasn't decisively affected at the mRNA level. However, Protocol B favoured bone and cartilage differentiation at the secretional level. Protocol A populations showed reduced purity, expressing CD105 in only 76% compared to the 96.7% in Protocol B cultures. Protocol A populations also contained significantly more (+4.2%) senescent cells, however, no difference was found in cell size between the two protocols. The findings of this study suggest that cell‐to‐cell contact, and therefore high confluence levels, is detrimental to MSC quality. © 2015 The Authors Journal of Tissue Engineering and Regenerative Medicine Published by John Wiley & Sons Ltd.

Autoserum: An Optimal Supplement for Bone Marrow Mesenchymal Stem Cells of Liver-Injured Rats. Stem Cells Int 2015; 2015:459580.

Abstract
Mesenchymal stem cells (MSCs) are an attractive source for the clinical cell therapy of liver injury. Although the use of adult serum, platelet lysate, or cord blood serum solves some of the problems caused by fetal bovine serum (FBS), the allogeneic immune response, contamination, and donor-to-donor and donor-to-receptor differences still obstruct the application of MSCs. In this study, the influences of autoserum from liver-injured rats (LIRs) and allogeneic serum from healthy rats on the isolation and culture of bone marrow MSCs (BMSCs) were examined and compared to FBS. The results showed that BMSCs cultured with autoserum or allogeneic serum exhibited better MSC-specific morphology, lower rate of cell senescent, and higher proliferation kinetics than those with FBS. In addition, autoserum promoted the osteogenic differentiation potential of BMSCs as allogeneic serum did. Although there were no significant differences in proliferation activity, immunophenotypic characterization, and differentiation potential between BMSCs cultured with autoserum and those with allogeneic serum, the potential adverse immunological reactions in patients with allogeneic material transplantation must be considered. We therefore believe that the autoserum from liver-injured patients may be a better choice for MSC expansion to meet the needs of liver injury therapy.

Abstract
Oncolytic viruses have demonstrated in pre-clinical and clinical studies safety and a unique pleiotropic activity profile of tumor destruction. Yet, their delivery suffers from virus inactivation by blood components and sequestration to healthy tissues. Therefore, mesenchymal stromal cells (MSCs) have been applied as carrier cells for shielded virus delivery to tumors after ex vivo infection with oncolytic viruses. However, infection and particle production by MSCs have remained unsatisfying. Here, we report engineered oncolytic adenoviruses (OAds) for improved virus production and delivery by MSCs. OAds are uniquely amenable to molecular engineering, which has facilitated improved tumor cell destruction. But for MSC-mediated regimens, OAd engineering needs to achieve efficient infection and replication in both MSCs and tumor cells. We show that an Ad5/3 chimeric OAd capsid, containing the adenovirus serotype 3 cell-binding domain, strongly increases the entry into human bone marrow-derived MSCs and into established and primary pancreatic cancer cells. Further, we reveal that OAd with engineered post-entry functions-by deletion of the anti-apoptotic viral gene E1B19K or expression of the death ligand TRAIL--markedly increased virus titers released from MSCs, while MSC migration was not hampered. Finally, these virus modifications, or viral expression of FCU1 for local 5-FC prodrug activation, improved tumor cell killing implementing complementary cytotoxicity profiles in a panel of pancreatic cancer cell cultures. Together, our study establishes post-entry modification of OAd replication for improving virus delivery by carrier cells and suggests a panel of optimized OAds for future clinical development in personalized treatment of pancreatic cancer.

Abstract
BACKGROUND Human adipose tissue (AT) is an ideal stem cell source for autologous cell-based therapies. The preferred setting for tissue engineering and regenerative medicine applications is the availability of clinically acceptable off-the-shelf cells and cell products. As AT is not always available for use, cryopreserved tissue represents an alternative approach. The aim of the present study was to compare the different properties of mesenchymal stem cells (MSCs) isolated from cryopreserved AT. We have measured cell recovery, viability, phenotype, proliferative potential, and differentiation into mesenchymal (adipogenic, osteogenic, chondrogenic) and nonmesenchymal (neuron-like cells) lineages. MATERIALS AND METHODS AT (n = 10) was harvested from donors and either processed fresh or cryopreserved in liquid nitrogen dewars. Both fresh and thawed tissues were enzymatically digested. MSCs were analyzed by fluorescence-activated cell sorting for CD3, CD14, CD19, CD34, CD44, CD45, CD73, CD90, and CD105 expression. Growth characteristics of both groups were investigated for population doublings, doubling time, saturation density, and plating efficiency. MSCs derived from fresh and thawed tissues were assessed for differentiation potential both qualitatively and quantitatively. RESULTS Adherent cells from fresh and thawed tissues displayed similar fibroblastic morphology. Cryopreservation did not alter expression of phenotypic markers. Similarly, the proliferative potential of MSCs was not compromised by cryopreservation. Furthermore, cryopreservation did not alter the differentiation capability of MSCs as determined with histochemistry, immunofluorescence, and real time reverse transcriptase-polymerase chain reaction. CONCLUSIONS We conclude that human AT could be successfully cryopreserved for future clinical application and the recovered MSCs were equivalent in functionality to the freshly processed MSCs.

Abstract
OBJECTIVES Although clinical applications using mesenchymal stromal cells (MSCs) are becoming more frequent, procedures for their in vitro culture are far from standardized. Growth factors such as FGF-2 are frequently added during expansion to improve population growth and differentiation characteristics. However, up to now its influence on surface marker distribution of MSCs has been close to unknown. The purpose of this study was therefore to analyse effects of FGF-2 supplementation on pre-selection of MSC subpopulations. MATERIALS AND METHODS Mesenchymal stromal cells were harvested from bone marrow of six patients and expanded in alpha-MEM or DMEM-LG. Starting in passage 2, 10 ng/ml FGF-2 was administered and non-supplemented media were used as controls. Growth indices were calculated from P0 to P4. After P4, fluorescence cytometry for common MSC surface markers was performed and standard chondrogenic, adipogenic and osteogenic differentiation protocols were applied. RESULTS Cell population growth indices were higher for those in FGF-2 supplemented media. Significant differences in surface marker distribution were observed for CD13, CD14, CD49, CD90, CD340 and STRO-1 depending on respective culture conditions. FGF-2 suppressed CD146 expression in both alpha-MEM and DMEM-LG. No differences in adipogenic and osteogenic differentiation potential could be observed, while FGF-2 significantly improved chondrogenic differentiation in DMEM-LG. CONCLUSIONS While holding the benefit of improving MSC chondrogenic differentiation potential, FGF-2 pre-selects certain MSC subtypes. Our data clearly show that expansion culture conditions have a significant effect on distribution of a number of MSC surface markers.

Abstract
Orthopedic implants including engineered bone tissue are commonly tested in sheep. To avoid rejection of heterologous or xenogeneic cells, autologous cells are preferably used, that is, ovine mesenchymal stem cells (oMSC). Unlike human MSC, ovine MSC are not well studied regarding isolation, expansion, and characterization. Here we investigated the impact of culture media composition on growth characteristics, differentiation, and surface antigen expression of oMSC. The culture media varied in fetal calf serum (FCS) content and in the addition of supplements and/or additional epidermal growth factor (EGF). We found that FCS strongly influenced oMSC proliferation and that specific combinations of supplemental factors (MCDB-201, ITS-plus, dexamethasone, and L-ascorbic acid) determined the expression of surface epitopes. We compared two published protocols for oMSC differentiation towards the osteogenic, adipogenic, and chondrogenic fate and found (i) considerable donor to donor variations, (ii) protocol-dependent variations, and (iii) variations resulting from the preculture medium composition. Our results indicate that the isolation and culture of oMSC in different growth media are highly variable regarding oMSC phenotype and behaviour. Furthermore, variations from donor to donor critically influence growth rate, surface marker expression, and differentiation.

Abstract
The regenerative potential of mesenchymal stromal cells (MSC) holds great promise in using them for treatment of a wide range of debilitating diseases. Several types of culture media and systems have been used for large-scale expansion of MSCs in vitro; however, the majority of them rely heavily on using foetal bovine serum (FBS)-supplement for optimal cell proliferation. FBS-based cultures pose the potential threat of spread of transmissible spongiform encephalopathy and bovine spongiform encephalopathy to MSCs and then to their recipients. A recent trend in cell culture is to change from serum-use to serum-free media (SFM). In this context, the current review focuses specifically on employment of various SFM for MSCs and discusses existences of various options with which to substitute FBS. In addition, we analyse MSC population growth kinetic patterns using various SFM for large-scale production of MSCs.

Abstract
Background Bone marrow-derived mesenchymal stromal cells (BM-MSCs) play an important role in modern tissue engineering, while distinct variations of culture media compositions and supplements have been reported. Because MSCs are heterogeneous regarding their regenerative potential and their surface markers, these parameters were compared in four widely used culture media compositions. Methods MSCs were isolated from bone marrow and expanded in four established cell culture media. MSC yield/1000 MNCs, passage time and growth index were observed. In P4, typical MSC surface markers were analysed by fluorescence cytometry. Additionally, chondrogenic, adipogenic and osteogenic differentiation potential were evaluated. Results Growth index and P0 cell yield varied importantly between the media. The different expansion media had a significant influence on the expression of CD10, CD90, CD105, CD140b CD146 and STRO-1. While no significant differences were observed regarding osteogenic and adipogenic differentiation, chondrogenic differentiation was superior in medium A as reflected by GAG/DNA content. Conclusions The choice of expansion medium can have a significant influence on growth, differentiation potential and surface marker expression of mesenchymal stromal cells, which is of fundamental importance for tissue engineering procedures.

Abstract
MSCs (mesenchymal stem cells) have attracted attention as a promising tool for regenerative medicine and transplantation therapy. MSCs exert neuroprotective effects by secreting a number of factors in vitro and in vivo. Similar characteristics are found in ADSCs (adipose-derived stem cells) and BMSCs (bone marrow stromal cells). Multipotent capability, easy accessibility and rapid proliferation of ADSCs have been established. Our main objective was to compare cell viability, growth rate, expression of neurotrophic factors and nestin genes in ADSCs and BMSCs. Cell doubling time and proliferation rate indicate that ADSCs has a higher proliferation rate than BMSCs. ADSCs and BMSCs express a similar pattern of CD71 and CD90 markers. Nestin immunostaining showed that ADSCs and BMSCs are immunopositive. The expression of neurotrophic factors genes in ADSCs proved similar to that of BMSCs genes. Thus adipose tissue stem cells with a high proliferation rate can express nestin and neurotrophic factor genes. Therefore ADSCs may be useful in future cell replacement therapies and help improve neurodegenerative diseases.

Abstract
Stem cell therapy and translational stem cell research require large-scale supply of stem cells at high purity and viability, thus leading to the development of stem cell separation technologies. This review covers key technologies being applied to stem cell separation, and also highlights exciting new approaches in this field. First, we will cover conventional separation methods that are commercially available and have been widely adapted. These methods include Fluorescence-activated cell sorting (FACS), Magnet-activated cell sorting (MACS), pre-plating, conditioned expansion media, density gradient centrifugation, field flow fractionation (FFF), and dielectrophoresis (DEP). Next, we will introduce emerging novel methods that are currently under development. These methods include improved aqueous two-phase system, systematic evolution of ligands by exponential enrichment (SELEX), and various types of microfluidic platforms. Finally, we will discuss the challenges and directions towards future breakthroughs for stem cell isolation. Advancing stem cell separation techniques will be essential for clinical and research applications of stem cells.

Abstract
Many active principles produced by animals, plants and microorganisms have been employed in the development of new drugs for the treatment of human diseases. Among animals known to produce pharmacologically active molecules that interfere in human cell physiology, the caterpillar Lonomia obliqua has become the focus of toxicological studies due to recent findings about its venom constituents. The objective of this study was to investigate the effects of L. obliqua venom upon the viability and the proliferation of different cell lineages and to propose mechanisms for the herein observed induction of cell proliferation in glioma cell lines. MTT analyses indicate that L. obliqua venom increases the viability of tumor cell lines U138-MG and HT-29; on the other hand, it inhibits the viability of V-79 nontumor cells. Cell count based on the trypan blue exclusion method suggests a proliferating activity of the venom upon U138-MG cells. Exposure of U138-MG to crude venom extract led to a decrease in the production of nitric oxide, and activation of the cAMP signaling pathway inhibited the effects of the venom, indicating that these mechanisms may influence cell proliferation triggered by the venom. Despite the proliferative effects of crude venom on U138-MG and HT-29 cell cultures, a protein purified from L. obliqua hemolymph previously shown to have cytoprotective activity had no effect on U138-MG and HT-29; however, this same protein increased the viability of V-79 cells that had previously been exposed to the cytotoxic activity of the crude venom extract. This study indicates that the venom and the antiapoptotic protein act differently and have different effects on cell cultures, depending on the cell line analyzed. Biomolecules displaying either mitogenic or cytotoxic activities are of great biotechnological interest. Further studies encompassing the purification of active principles from L. obliqua venom are necessary to further elucidate its effects on different cell types.

Abstract
Salivary gland stem/progenitor cells belong to the endodermal lineage and may serve as good candidates to replace their dysfunctional counterparts. The objective of this study was to isolate large numbers of salivary gland tissue-derived stem cells (SGSCs) from adult rats in order to develop a clinically applicable method that does not involve sorting or stem cell induction by duct ligation. We analysed SGSCs isolated from normal rat salivary glands to determine whether they retained the major characteristics of stem cells, self-renewal and multipotency, especially with respect to the various endodermal cell types. SGSCs expressed high levels of integrin α6β1 and c-kit, which are surface markers of SGSCs. In particular, the integrin α6β1(+) /c-kit(+) salivary gland cells maintained the morphology, proliferation activity and multipotency of stem cells for up to 92 passages in 12 months. Furthermore, we analysed the capacity of SGSCs to differentiate into endoderm lineage cell types, such as acinar-like and insulin-secreting cells. When cultured on growth factor reduced matrigel, the morphology of progenitor cells changed to acinar-like structures and these cells expressed the acinar cell-specific marker, α-amylase, and tight junction markers. Moreover, reverse transcription-polymerase chain reaction (RT-PCR) data showed increased expression of pancreatic cell markers, including insulin, Pdx1, pan polypeptide and neurogenin-3, when these cells formed pancreatic clusters in the presence of activin A, exendin-4 and retinoic acid. These data demonstrate that adult salivary stem/progenitor cells may serve as a potential source for cell therapy in salivary gland hypofunction and diabetes.

Abstract
Human mesenchymal stem cells (hMSCs) are presently being evaluated for their therapeutic potential in clinical studies to treat various diseases, disorders, and injuries. To date, early-phase studies have indicated that the use of both autologous and allogeneic hMSCs appear to be safe; however, efficacy has not been demonstrated in recent late-stage clinical trials. Optimized cell bioprocessing protocols may enhance the efficacy as well as safety of hMSC therapeutics. Classical media used for generating hMSCs are typically supplemented with ill-defined supplements such as fetal bovine serum (FBS) or human-sourced alternatives. Ideally, culture media are desired to have well-defined serum-free formulations that support the efficient production of hMSCs while maintaining their therapeutic and differentiation capacity. Towards this objective, we review here current cell culture media for hMSCs and discuss medium development strategies.

Abstract
Human mesenchymal stem cells (hMSCs) are typically obtained for research or therapeutic applications by isolating and subculturing adherent cells from bone marrow on tissue-culture substrates using growth media. The purity and properties of the resulting populations can be affected greatly by the conditions under which they are cultured. Fetal bovine serum (FBS), although ill-defined, has been widely used as a critical requirement for conventional hMSC culture. However, a defined serum-free medium would greatly facilitate the development of robust, clinically acceptable bioprocesses for reproducibly generating quality-assured cells. The present study provides evidence demonstrating that a defined serum-free medium (PPRF-msc6) shows several beneficial features over a conventional FBS-containing medium for the production of hMSCs. When compared to control FBS-based cultures, PPRF-msc6 medium supported the derivation of hMSCs from primary cultures of bone marrow cells in a more rapid and consistent manner. Furthermore, hMSCs cultured in PPRF-msc6 exhibited: (a) a greater colony-forming capacity in primary as well as passaged cultures; (b) negligible lag phase and explicit exponential growth; (c) lower population doubling times (21-26 h vs 35-38 h between passage levels 1 and 10); (d) a greater number of population doublings (62 ± 4 vs 43 ± 2; over a 2 month period); and (e) a higher degree of homogeneity in size. Our data demonstrate that PPRF-msc6 is an important development which opens the door for the rapid, efficient and reproducible production of hMSCs in clinical settings.

Abstract
Mesenchymal stromal cells (MSCs) do not express a unique definite epitope or marker gene. As such, minimal criteria were recently established for defining multipotent MSC. These criteria include expression of CD73, CD90, CD105, and a lack of hematopoietic marker expression. However, we detected binding of a CD14 antibody on bone marrow- and placenta-derived MSC and investigated the staining of CD14 antibodies on these MSC in more detail. The MSC were isolated from human bone marrow and placenta tissue, expanded, characterized by quantitative RT-PCR, flow cytometry, and immunocytochemistry and differentiated to generate osteoblasts, chondrocytes, and adipocytes. The CD14-cross-reactive MSCs were enriched by cell sorting. Human peripheral blood mononuclear cells, fibroblasts, and hematopoietic cell lines served as controls. Utilizing four different clones of CD14 monoclonal antibodies, we found that three CD14 reagents stained the MSC. Two CD14 antibodies (HCD14 and M5E2) clearly marked the CD90(+) MSC population with distinct intensities, clone 134 620 generated a shift in flow cytometry histograms, but clone MΦP9 did not stain MSC. Transcripts encoding CD14 or the CD14 protein were not detected in MSC. We confirm that bone marrow- and placenta-derived MSC do not express CD14 and that the CD14 antibody MΦP9 discriminates between monocytes and MSC more efficiently than the other antibodies employed here. This investigation does not contradict previous work but provides a more accurate characterization of MSC.

Abstract
Skeletal stem cells (SSCs) show great capacity for bone and cartilage repair however, current in vitro cultures are heterogeneous displaying a hierarchy of differentiation potential. SSCs represent the diminutive true multipotent stem cell fraction of bone marrow mononuclear cell (BMMNC) populations. Endeavours to isolate SSCs have generated a multitude of separation methodologies. SSCs were first identified and isolated by their ability to adhere to culture plastic. Once isolated, further separation is achieved via culture in selective or conditioned media (CM). Indeed, preferential SSC growth has been demonstrated through selective in vitro culture conditions. Other approaches have utilised cell morphology (size and shape) as selection criteria. Studies have also targeted SSCs based on their preferential adhesion to specified compounds, individually or in combination, on both macro and microscale platforms. Nevertheless, most of these methods which represent macroscale function with relatively high throughput, yield insufficient purity. Consequently, research has sought to downsize isolation methodologies to the microscale for single cell analysis. The central approach is identification of the requisite cell populations of SSC-specific surface markers that can be targeted for isolation by either positive or negative selection. SELEX and phage display technology provide apt means to sift through substantial numbers of candidate markers. In contrast, single cell analysis is the paramount advantage of microfluidics, a relatively new field for cell biology. Here cells can be separated under continuous or discontinuous flow according to intrinsic phenotypic and physicochemical properties. The combination of macroscale quantity with microscale specificity to generate robust high-throughput (HT) technology for pure SSC sorting, isolation and enrichment offers significant implications therein for skeletal regenerative strategies as a consequence of lab on chip derived methodology.

Abstract
BACKGROUND AIMS The potential of cultured adipose-derived stem cells (ASC) in regenerative medicine and new cell therapeutic concepts has been shown recently by many investigations. However, while the method of isolation of ASC from liposuction aspirates depending on plastic adhesion is well established, a standard expansion medium optimally maintaining the undifferentiated state has not been described. METHODS We cultured ASC in five commonly used culture media (two laboratory-made media and three commercially available media) and compared them with a standard medium. We analyzed the effects on cell morphology, proliferation, hepatocyte growth factor (HGF) expression, stem cell marker profile and differentiation potential. Proliferation was measured with a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and a fluorescent assay. Release of HGF was assessed by an immunoassay. Expression of characteristic stem cell-related transcription factors and markers was evaluated by quantitative polymerase chain reaction (qPCR) (Nanog, Sox-2, Rex-1, nestin and Oct-4) and flow cytometry (CD44, CD73, CD90, CD105 and CD166), and differentiation was shown by adipogenic medium. RESULTS The morphology and expansion of ASC were significantly affected by the media used, whereas none of the media influenced the ASC potential to differentiate into adipocytes. Furthermore, two of the media induced an increase in expression of transcription factors, an increased secretion of HGF and a decrease in CD105 expression. CONCLUSIONS Culture of ASC in one of these two media before using the cells in cell therapeutic approaches may have a benefit on their regenerative potential.

Abstract
This study evaluated healing of equine metacarpal/metatarsal osteotomies in response to percutaneous injection of autologous dermal fibroblasts (DFbs) genetically engineered to secrete bone morphogenetic protein-2 (BMP2) or demonstrate green fluorescent protein (GFP) gene expression administered 14 days after surgery. Radiographic assessment of bone formation indicated greater and earlier healing of bone defects treated with DFb with BMP2 gene augmentation. Quantitative computed tomography and biomechanical testing revealed greater mineralized callus and torsional strength of DFb-BMP2-treated bone defects. On the histologic evaluation, the bone defects with DFb-BMP2 implantation had greater formation of mature cartilage and bone nodules within the osteotomy gap and greater mineralization activity on osteotomy edges. Autologous DFbs were successfully isolated in high numbers by a skin biopsy, rapidly expanded without fastidious culture techniques, permissive to adenoviral vectors, and efficient at in vitro BMP2 protein production and BMP2-induced osteogenic differentiation. This study demonstrated an efficacy and feasibility of DFb-mediated BMP2 therapy to accelerate the healing of osteotomies. Skin cell-mediated BMP2 therapy may be considered as a potential treatment for various types of fractures and bone defects.

Abstract
Endometriosis is a chronic disease characterized by the presence of ectopic endometrial tissue outside of the uterus with mixed traits of benign and malignant pathology. In this study we analyzed in endometrial and endometriotic tissues the differential expression of a panel of genes that are involved in preservation of stemness status and consequently considered as markers of stem cell presence. The expression profiles of a panel of 13 genes (SOX2, SOX15, ERAS, SALL4, OCT4, NANOG, UTF1, DPPA2, BMI1, GDF3, ZFP42, KLF4, TCL1) were analyzed by reverse transcription-polymerase chain reaction in human endometriotic (n = 12) and endometrial samples (n = 14). The expression of SALL4 and OCT4 was further analyzed by immunohistochemical methods. Genes UTF1, TCL1, and ZFP42 showed a trend for higher frequency of expression in endometriosis than in endometrium (P < 0.05 for UTF1), whereas GDF3 showed a higher frequency of expression in endometrial samples. Immunohistochemical analysis revealed that SALL4 was expressed in endometriotic samples but not in endometrium samples, despite the expression of the corresponding mRNA in both the sample groups. This study highlights a differential expression of stemness-related genes in ectopic and eutopic endometrium and suggests a possible role of SALL4-positive cells in the pathogenesis of endometriosis.

Abstract
The objective of this study was to determine whether surface-modified nanoparticles enhance permeability across nasal mucosa, while retaining the effectiveness of the payload. The uptake and permeability of polystyrene nanoparticles (PS-NPs; FluoSpheres) was evaluated across the various regions of the bovine nasal epithelia following conjugation with deslorelin and transferrin. Uptake and transport of PS-NPs, deslorelin-PS-NPs, and transferrin-PS-NPs exhibited regional differences in the order: inferior turbinate posterior (ITP) > medium turbinate posterior (MTP) > medium turbinate anterior (MTA). Uptake and transport also exhibited directionality and temperature dependence in these tissues. Further, uptake as well as transport of functionalized nanoparticles could be inhibited by excess free functionalizing ligand. Confocal microscopy indicated the presence of functionalized nanoparticles in respiratory epithelial cells, as well as other cell types of the nasal tissue. We chose the ITP region for further studies with deslorelin or transferrin-conjugated poly-l-lactide-co-glycolide nanoparticles (PLGA-NPs) encapsulating an anti-VEGF intraceptor (Flt23k) plasmid. Transport of the nanoparticles, as well as the plasmid from the nanoparticles, exhibited the following order: transferrin-PLGA-NPs > deslorelin-PLGA-NPs > PLGA-NPs >> plasmid. The ability of the nanoparticles transported across the nasal tissue to retain the effectiveness of the Flt23k plasmid was evaluated by measuring transfection efficiency (percentage of cells expressing GFP) and VEGF inhibition in LNCaP and PC-3 prostate cancer cells. Transfection efficiencies and VEGF inhibition in LNCaP and PC-3 cells exhibited the following trend: transferrin-PLGA-NPs >or= deslorelin-PLGA-NPs > PLGA-NPs >> plasmid. Further, functionalized nanoparticles exhibited transfection efficiencies and VEGF inhibition significantly superior compared with the routinely used transfecting agent, lipofectamine. Formulating plasmids into nanoparticulate delivery systems enhances the transnasal delivery and gene therapy at remote target cancer cells, which can be further enhanced by nanoparticle functionalization with deslorelin or transferrin.

Abstract
Current standard techniques for bone tissue engineering utilize ex vivo expanded osteogenic cells. However, ex vivo expansion requires serum, which may hinder clinical applications. Here, we report the feasibility and efficacy of bone tissue engineering with human bone marrow stromal cells (BMSCs) expanded in serum-free conditions. Bone marrow was aspirated from 4 healthy donors and adherent cells were cultured in either serum-free medium (STEMPRO((R)) MSC SFM) or conventional serum-containing medium (alpha-MEM supplemented with 10% serum). Efficacy of expansion was greater in serum-free medium. Phenotypically, serum-free expanded BMSCs were smaller in cell-size and showed expression of CD105(++) and CD146(dim). After osteogenic induction, serum-free expanded BMSCs showed lower alkaline phosphatase activity. However, they showed higher responsiveness to induction. In vivo bone-forming ability was also confirmed. In conclusion, bone tissue engineering with serum-free expanded BMSCs is feasible and as efficient as that obtained with BMSCs expanded in conventional serum-containing medium.
