Effects of Umbilical Cord Management Strategies on Stem Cell Transfusion, Delivery Room Adaptation, and Cerebral Oxygenation in Term and Late Preterm Infants. Front Pediatr 2022; 10:838444. [PMID: 35444969 PMCID: PMC9013943 DOI: 10.3389/fped.2022.838444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 02/21/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND The umbilical cord blood contains a high concentration of stem cells. There is not any published study evaluating the amount of stem cells that have the potential to be transferred to the infant through placental transfusion methods as delayed cord clamping (DCC) and umbilical cord milking (UCM). The aim of this study is to measure the concentrations of endothelial progenitor cell (EPC) and CD34+ hematopoietic stem cell (HSC) in the placental residual blood volume (PRBV), and evaluate the delivery room adaptation and cerebral oxygenation of these infants. METHODS Infants with ≥36 gestational weeks were randomized to receive DCC (120 s), UCM, or immediate cord clamping (ICC). EPC and CD34+ HSC were measured by flow cytometry from the cord blood. PRBV was collected in the setup. The cord blood gas analysis and complete blood count were performed. The heart rate (HR), oxygen saturation (SpO2), and cerebral regional oxygen saturation (crSO2) were recorded. RESULTS A total of 103 infants were evaluated. The amount of PRBV (in ml and ml/kg) was higher in the ICC group (p < 0.001). The number of EPCs in the PRBV content (both ml and ml/kg) were the highest in the ICC group (p = 0.002 and p = 0.001, respectively). The number of CD34+ HSCs in PRBV content (ml and ml/kg) was similar in all groups, but nonsignificantly higher in the ICC group. The APGAR scores at the first and fifth min were lower in the ICC group (p < 0.05). The mean crSO2 values were higher at the 3rd and 10th min in the DCC group (p = 0.042 and p = 0.045, respectively). cFOE values were higher at the 3rd and 10th min in the ICC group (p = 0.011 and p < 0.001, respectively). CONCLUSION This study showed that placental transfusion methods, such as DCC and UCM, provide both higher blood volume, more stem cells transfer to the infant, and better cerebral oxygenation in the first minutes of life, whereas many lineages of stem cells is lost to the placenta by ICC with higher residual blood volume. These cord management methods rather than ICC do not require any cost or technology, and may be a preemptive therapeutic source for diseases of the neonatal period.

Abstract
MicroRNAs (miRNAs) are endogenous short non-encoding RNAs which play a critical role on the output of the proteins, and influence multiple biological characteristics of the cells and physiological processes in the body. Mesenchymal stem/stromal cells (MSCs) are adult multipotent stem cells and characterized by self-renewal and multidifferentiation and have been widely used for disease treatment and regenerative medicine. Meanwhile, MSCs play a critical role in maintaining homeostasis in the body, and dysfunction of MSC differentiation leads to many diseases. The differentiation of MSCs is a complex physiological process and is the result of programmed expression of a series of genes. It has been extensively proven that the differentiation process or programmed gene expression is also regulated accurately by miRNAs. The differentiation of MSCs regulated by miRNAs is also a complex, interdependent, and dynamic process, and a full understanding of the role of miRNAs will provide clues on the appropriate upregulation or downregulation of corresponding miRNAs to mediate the differentiation efficiency. This review summarizes the roles and associated signaling pathways of miRNAs in adipogenesis, chondrogenesis, and osteogenesis of MSCs, which may provide new hints on MSCs or miRNAs as therapeutic strategies for regenerative medicine and biotherapy for related diseases.

Effect of Nanostructured Scaffold on Human Adipose-Derived Stem Cells: Outcome of In Vitro Experiments. NANOMATERIALS 2020; 10:nano10091822. [PMID: 32932658 PMCID: PMC7558271 DOI: 10.3390/nano10091822] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 08/26/2020] [Accepted: 09/10/2020] [Indexed: 12/11/2022]
Abstract
This work is addressed to provide, by in vitro experiments, results on the repercussion that a nanostructured scaffold could have on viability, differentiation and secretion of bioactive factors of human adipose-derived stem cells (hASCs) when used in association to promote angiogenesis, a crucial condition to favour tissue regeneration. To achieve this aim, we evaluated cell viability and morphology by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay and microscopy analysis, respectively. We also investigated the expression of some of those genes involved in angiogenesis and differentiation processes utilizing quantitative polymerase chain reaction (qPCR), whereas the amounts of Vascular Endothelial Growth Factor A, Interleukin 6 and Fatty Acid-Binding Protein 4 secreted in the culture medium, were quantified by enzyme-linked immunosorbent assay (ELISA). Results suggested that, in the presence of the scaffold, cell proliferation and the exocytosis of factors involved in the angiogenesis process are reduced; by contrast, the expression of those genes involved in hASC differentiation appeared enhanced. To guarantee cell survival, the construct dimensions are, generally, smaller than clinically required. Furthermore, being the paracrine event the primary mechanism exerting the beneficial effects on injured tissues, the use of conditioned culture medium instead of cells may be convenient.

Abstract
In the last couple of decades, there has been a growing optimism surrounding the potential transformative use of human mesenchymal stem cells (MSCs) and human-induced pluripotent stem cells (iPSCs) for regenerative medicine and disease treatment. In order for this to occur, it is first essential to understand the mechanisms underpinning their cell-fate specification, which includes cell signaling via gap junctional intercellular communication. Here, we investigated the role of the prototypical gap junction protein, connexin43 (Cx43), in governing the differentiation of iPSCs into MSCs and MSC differentiation along the adipogenic lineage. We found that control iPSCs, as well as iPSCs derived from oculodentodigital dysplasia patient fibroblasts harboring a GJA1 (Cx43) gene mutation, successfully and efficiently differentiated into LipidTox and perilipin-positive cells, indicating cell differentiation along the adipogenic lineage. Furthermore, the complete CRISPR-Cas9 ablation of Cx43 from iPSCs did not prevent their differentiation into bona fide MSCs or pre-adipocytes, strongly suggesting that even though Cx43 expression is upregulated during adipogenesis, it is expendable. Interestingly, late passage Cx43-ablated MSCs senesced more quickly than control cells, resulting in failure to properly differentiate in vitro. We conclude that despite being upregulated during adipogenesis, Cx43 plays no detectable role in the early stages of human iPSC-derived MSC adipogenic differentiation. However, Cx43 may play a more impactful role in protecting MSCs from premature senescence.

Autophagy enhances mesenchymal stem cell-mediated CD4 + T cell migration and differentiation through CXCL8 and TGF-β1. Stem Cell Res Ther 2019; 10:265. [PMID: 31443687 PMCID: PMC6708254 DOI: 10.1186/s13287-019-1380-0] [Citation(s) in RCA: 47] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 07/23/2019] [Accepted: 08/12/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Mesenchymal stem cells (MSCs) have been recognized as a promising tool for the treatment of various inflammatory disorders and autoimmune diseases. Stress conditions affect immune-mediated treatment and activate autophagy in MSCs. However, whether autophagy affects the MSC-mediated recruitment and differentiation of CD4+ T cells remains elusive. METHODS MSCs were pretreated with 3-methyladenine (3-MA) and rapamycin to regulate autophagy, and then co-cultured with CD4+ T cells. CD4+ T cell migration and differentiation were detected by flow cytometry. Further, gene expression levels of well-known chemokines were analyzed by quantitative real-time PCR. Enzyme-linked immunosorbent assays and western blot analysis were performed to detect C-X-C motif chemokine ligand 8 (CXCL8) and transforming growth factor (TGF)-β1 protein levels. An exogenous antibody and short hairpin RNA were used to regulate CXCL8 and TGF-β1 levels, which enabled us to evaluate how autophagy affected MSC-mediated CD4+ T cell migration and differentiation. RESULTS 3-MA inhibited autophagy in MSCs, which was activated by rapamycin. Rapamycin increased the migration of CD4+ T cells, whereas 3-MA decreased their migration. Mechanistically, we found that autophagy strengthened CXCL8 secretion, and the addition of exogenous CXCL8 and an anti-CXCL8 antibody eliminated the difference of CD4+ T cell migration among groups. Further, the ratio of regulatory T (Treg) cells was increased in rapamycin-pretreated MSCs, but the ratio of T helper 1 (Th1) cells was decreased, while pretreatment of MSCs with 3-MA induced the opposite effect compared with the control group. TGF-β1 overexpression and knockdown using lentiviruses rectified the differences in the ratios of Treg and Th1 cells among the groups. CONCLUSION This study demonstrates that autophagy of mesenchymal stem cells mediates CD4+ T cell migration and differentiation through CXCL8 and TGF-β1, respectively. These results provide a potential new strategy for improving MSC-mediated therapy.

Abstract
Ex vivo expansion of hematopoietic progenitors is considered as an attractive tool to increase the number of stem and progenitor cells (HSPCs) for cell therapy. The efficacy of ex vivo expansion is strongly depends on the feeder cell activity to mimic hematopoietic microenvironment. Here we demonstrated, that combination of mitomycin C-induced growth arrest and tissue-related O2 (physiological hypoxia) modulated stromal capacity of adipose tissue derived stromal cells (ASCs). Growth arrest did not affect viability, stromal phenotype and multilineage potential of ASCs permanently expanded at tissue-related O2. Meanwhile, the PCR analysis revealed an up-regulation of genes, encoded molecules of cell-cell (ICAM1, HCAM/CD44) and cell-matrix adhesion (ITGs), extracellular matrix production (COLs) and remodeling (MMPs, HAS1) in growth-arrested ASCs at physiological hypoxia in comparison with ambient O2 (20%). The number of ICAM-1 positive ASCs was increased under low O2 as well. These alterations contributed into the ex vivo expansion of cord blood HSPCs providing the preferential production of primitive HSPCs. The number of cobblestone area forming cell (CAFC) colonies was 1.5-fold higher at physiological hypoxia (p < 0.05). CAFCs considered as long-term culture-initiating cells (LTC-IC) known to support long-term hematopoiesis restoration in vivo. The presented data may be applicable in the development of upscale protocols of HSPC expansion.

Abstract
Tissue engineering is a very promising field of regenerative medicine. Life expectancy has been increasing, and tissue replacement is increasingly needed in patients suffering from various degenerative disorders of the organs. The use of adult mesenchymal stem cells (e.g. from adipose tissue or from bone marrow) in tissue engineering seems to be a promising approach for tissue replacements. Clinical applications can make direct use of the large secretome of these cells, which can have a positive influence on other cells around. Another advantage of adult mesenchymal stem cells is the possibility to differentiate them into various mature cells via appropriate culture conditions (i.e. medium composition, biomaterial properties, and dynamic conditions). This review is focused on current and future ways to carry out tissue replacement of damaged bones and blood vessels, especially with the use of suitable adult mesenchymal stem cells as a potential source of differentiated mature cells that can later be used for tissue replacement. The advantages and disadvantages of different stem cell sources are discussed, with a main focus on adipose-derived stem cells. Patient factors that can influence later clinical applications are taken into account.

Abstract
SummaryHuman umbilical cord matrix/Wharton's Jelly (hUC)-derived mesenchymal stem cells (MSC) have been shown to have marked therapeutic effects in a number of inflammatory diseases and autoimmune diseases in humans based on their potential for immunosuppression and their low immunogenicity. Currently, no data are available on the effectiveness of UC-MSC transplantation in immune thrombocytopenia (ITP) patients. It was the objective of this study to assess the effect of allogeneic UC-MSCs on ITP patients in vitro and in vivo. Peripheral blood mononuclear cells (PBMCs) and bone marrow mononuclear cells (BM-MNCs) from ITP patients and healthy controls were co-cultured with UC-MSCs for three days and seven days, respectively. Flow cytometry and ELISA were applied to assess the various parameters. In PBMCs from ITP patients, the proliferation of autoreactive T, B lymphocytes and destruction of autologous platelets were dramatically suppressed by UC-MSCs. UC-MSCs not only suppressed co-stimulatory molecules CD80, CD40L and FasL expression but also in shifting Th1/Th2/Treg cytokines profile in ITP patients. UC-MSCs obviously reversed the dysfunctions of megakaryocytes by promoting platelet production and decreasing the number of living megakaryocytes as well as early apoptosis. In addition, the level of thrombopoietin was increased significantly. Our clinical study showed that UC-MSCs play a role in alleviating refractory ITP by increasing platelet numbers. These findings suggested that UC-MSCs transplantation might be a potential therapy for ITP.

Abstract
Human amniotic fluid cells are immune-privileged with low immunogenicity and anti-inflammatory properties. They are able to self-renew, are highly proliferative, and have a broad differentiation potential, making them amenable for cell-based therapies. Amniotic fluid (AF) is routinely obtained via amniocentesis and contains heterogeneous populations of foetal-derived progenitor cells including mesenchymal stem cells (MSCs). In this study, we isolated human MSCs from AF (AF-MSCs) obtained during Caesarean sections (C-sections) and characterized them. These AF-MSCs showed typical MSC characteristics such as morphology, in vitro differentiation potential, surface marker expression, and secreted factors. Besides vimentin and the stem cell marker CD133, subpopulations of AF-MSCs expressed pluripotency-associated markers such as SSEA4, c-Kit, TRA-1-60, and TRA-1-81. The secretome and related gene ontology (GO) terms underline their immune modulatory properties. Furthermore, transcriptome analyses revealed similarities with native foetal bone marrow-derived MSCs. Significant KEGG pathways as well as GO terms are mostly related to immune function, embryonic skeletal system, and TGFβ-signalling. An AF-MSC-enriched gene set included putative AF-MSC markers PSG5, EMX-2, and EVR-3. In essence, C-section-derived AF-MSCs can be routinely obtained and are amenable for personalized cell therapies and disease modelling.

Abstract
Glioblastoma, also known as glioblastoma multiforme (GBM), is the most recurrent and malignant astrocytic glioma found in adults. Biologically, GBMs are highly aggressive tumors that often show diffuse infiltration of the brain parenchyma, making complete surgical resection difficult. GBM is not curable with surgery alone because tumor cells typically invade the surrounding brain, rendering complete resection unsafe. Consequently, present-day therapy for malignant glioma remains a great challenge. The location of the invasive tumor cells presents several barriers to therapeutic delivery. The blood-brain barrier regulates the trafficking of molecules to and from the brain. While high-grade brain tumors contain some "leakiness" in their neovasculature, the mechanisms of GBM onset and progression remain largely unknown. Recent advances in the understanding of the signaling pathways that underlie GBM pathogenesis have led to the development of new therapeutic approaches targeting multiple oncogenic signaling aberrations associated with the GBM. Among these, drug delivery nanosystems have been produced to target therapeutic agents and improve their biodistribution and therapeutic index in the tumor. These systems mainly include polymer or lipid-based carriers such as liposomes, metal nanoparticles, polymeric nanospheres and nanocapsules, micelles, dendrimers, nanocrystals, and nanogold. Photodynamic therapy (PDT) is a promising treatment for a variety of oncological diseases. PDT is an efficient, simple, and versatile method that is based on a combination of a photosensitive drug and light (generally laser-diode or laser); these factors are separately relatively harmless but when used together in the presence of oxygen molecules, free radicals are produced that initiate a sequence of biological events, including phototoxicity, vascular damage, and immune responses. Photodynamic pathways activate a cascade of activities, including apoptotic and necrotic cell death in both the tumor and the neovasculature, leading to a permanent lesion and destruction of GBM cells that remain in the healthy tissue. Glioblastoma tumors differ at the molecular level. For example, gene amplification epidermal growth factor receptor and its receptor are more highly expressed in primary GBM than in secondary GBM. Despite these distinguishing features, both types of tumors (primary and secondary) arise as a result dysregulation of numerous intracellular signaling pathways and have standard features, such as increased cell proliferation, survival and resistance to apoptosis, and loss of adhesion and migration, and may show a high degree of invasiveness. PDT may promote significant tumor regression and extend the lifetime of patients who experience glioma progression.

Abstract
Umbilical cord (UC) is a rich source of rapidly proliferating mesenchymal stem cells (MSCs) that are easily cultured on a large-scale. Clinical applications of UC-MSCs include graft-versus-host disease, and diabetes mellitus types 1 and 2. UC-MSCs should be isolated and proliferated according to good manufacturing practice (GMP) with animal component-free medium, quality assurance, and quality control for their use in clinical applications. This study developed a GMP standard protocol for UC-MSC isolation and culture. UC blood and UC were collected from the same donors. Blood vasculature was removed from UC. UC blood was used as a source of activated platelet rich plasma (aPRP). Small fragments (1-2 mm(2)) of UC membrane and Wharton's jelly were cut and cultured in DMEM/F12 medium containing 1 % antibiotic-antimycotic, aPRP (2.5, 5, 7.5 and 10 %) at 37 °C in 5 % CO2. The MSC properties of UC-MSCs at passage 5 such as osteoblast, chondroblast and adipocyte differentiation, and markers including CD13, CD14, CD29, CD34, CD44, CD45, CD73, CD90, CD105, and HLA-DR were confirmed. UC-MSCs also were analyzed for karyotype, expression of tumorigenesis related genes, cell cycle, doubling time as well as in vivo tumor formation in NOD/SCID mice. Control cells consisted of UC-MSCs cultured in DMEM/F12 plus 1 % antibiotic-antimycotic, and 10 % fetal bovine serum (FBS). All UC-MSC (n = 30) samples were successfully cultured in medium containing 7.5 and 10 % aPRP, 92 % of samples grew in 5.0 % aPRP, 86 % of samples in 2.5 % aPRP, and 72 % grew in 10 % FBS. UC-MSCs in these four groups exhibited similar marker profiles. Moreover, the proliferation rates in medium with PRP, especially 7.5 and 10 %, were significantly quicker compared with 2.5 and 5 % aPRP or 10 % FBS. These cells maintained a normal karyotype for 15 sub-cultures, and differentiated into osteoblasts, chondroblasts, and adipocytes. The analysis of pluripotent cell markers showed UC-MSCs maintained the expression of the oncogenes Nanog and Oct4 after long term culture but failed to transfer tumors in NOD/SCID mice. Replacing FBS with aPRP in the culture medium for UC tissues allowed the successful isolation of UC-MSCs that satisfy the minimum standards for clinical applications.

Abstract
Mesenchymal stem cells (MSC) have become a promising tool for cell therapy in regenerative medicine. They are readily available, demonstrate powerful differentiation capabilities and present immunosuppressive properties that aid them in surviving from host immune rejection for its great potential use in allograft. Currently clinical trials are underway using MSC, both culture-expanded allogeneic and autologous, for the treatment of a range of diseases not treatable by conventional therapies. A vast array of studies has dedicated towards the use of MSC for treating corneal diseases with very promising outcomes. MSC have successfully differentiated into keratocytes both in vitro and in vivo, and corneal epithelial cells in vitro, but it is uncertain if MSC can assume corneal epithelial cells in vivo. However, to date few studies have unequivocally established the efficacy of MSC for treating corneal endothelial defects. Currently, the diversity in protocols of the isolation and expansion of MSC are hindering to the assessment of cell treatment ability and the further development of treatment regimens. Therefore, future studies should develop international standards for MSC isolation and characterization. In this review, we discuss recent advances in MSC for treating ocular surface diseases.

Abstract
Tissue regeneration during wound healing or cancer growth and progression depends on the establishment of a cellular microenvironment. Mesenchymal stem cells (MSC) are part of this cellular microenvironment, where they functionally modulate cell homing, angiogenesis, and immune modulation. MSC recruitment involves detachment of these cells from their niche, and finally MSC migration into their preferred niches; the wounded area, the tumor bed, and the BM, just to name a few. During this recruitment phase, focal proteolysis disrupts the extracellular matrix (ECM) architecture, breaks cell-matrix interactions with receptors, and integrins, and causes the release of bioactive fragments from ECM molecules. MSC produce a broad array of proteases, promoting remodeling of the surrounding ECM through proteolytic mechanisms. The fibrinolytic system, with its main player plasmin, plays a crucial role in cell migration, growth factor bioavailability, and the regulation of other protease systems during inflammation, tissue regeneration, and cancer. Key components of the fibrinolytic cascade, including the urokinase plasminogen activator receptor (uPAR) and plasminogen activator inhibitor-1 (PAI-1), are expressed in MSC. This review will introduce general functional properties of the fibrinolytic system, which go beyond its known function of fibrin clot dissolution (fibrinolysis). We will focus on the role of the fibrinolytic system for MSC biology, summarizing our current understanding of the role of the fibrinolytic system for MSC recruitment and the functional consequences for tissue regeneration and cancer. Aspects of MSC origin, maintenance, and the mechanisms by which these cells contribute to altered protease activity in the microenvironment under normal and pathological conditions will also be discussed.

Abstract
Despite significant advancements in bone tissue-engineering applications, the clinical impact of bone marrow stromal cells (BMSCs) for the treatment of large osseous defects remains limited. Therefore, other cell sources are under investigation for their osteogenic potential to repair bone. In this study, tendon-derived stromal cells (TDSCs) were evaluated in comparison to BMSCs to support the functional repair of a 5 mm critical-sized, segmental defect in the rat femur. Analysis of the trilineage differentiation capacity of TDSCs and BMSCs cultured on collagen sponges revealed impaired osteogenic differentiation and mineral deposition of TDSCs in vitro, whereas chondrogenic and adipogenic differentiation was evident for both cell types. Radiographic assessment demonstrated that neither cell type significantly improved the healing rate of a challenging 5 mm segmental femoral defect. Transplanted TDSCs and BMSCs both led to the formation of only small amounts of bone in the defect area, and histological evaluation revealed non-mineralized, collagen-rich scar tissue to be present within the defect area. Newly formed lamellar bone was restricted to the defect margins, resulting in closure of the medullary cavity. Interestingly, in comparison to BMSCs, significantly more TDSC-derived cells were present at the osteotomy gap up to 8 weeks after transplantation and were also found to be located within newly formed lamellar bone, suggesting their capacity to directly contribute to de novo bone formation. To our knowledge, this is the first study investigating the in vivo capacity of TDSCs to regenerate a critical-sized defect in the rat femur. Copyright © 2015 John Wiley & Sons, Ltd.

A regulatory loop containing miR-26a, GSK3β and C/EBPα regulates the osteogenesis of human adipose-derived mesenchymal stem cells. Sci Rep 2015; 5:15280.

Abstract
Elucidating the molecular mechanisms responsible for osteogenesis of human adipose-derived mesenchymal stem cells (hADSCs) will provide deeper insights into the regulatory mechanisms of this process and help develop more efficient methods for cell-based therapies. In this study, we analysed the role of miR-26a in the regulation of hADSC osteogenesis. The endogenous expression of miR-26a increased during the osteogenic differentiation. The overexpression of miR-26a promoted hADSC osteogenesis, whereas osteogenesis was repressed by miR-26a knockdown. Additionally, miR-26a directly targeted the 3′UTR of the GSK3β, suppressing the expression of GSK3β protein. Similar to the effect of overexpressing miR-26a, the knockdown of GSK3β promoted osteogenic differentiation, whereas GSK3β overexpression inhibited this process, suggesting that GSK3β acted as a negative regulator of hADSC osteogenesis. Furthermore, GSK3β influences Wnt signalling pathway by regulating β-catenin, and subsequently altered the expression of its downstream target C/EBPα. In turn, C/EBPα transcriptionally regulated the expression of miR-26a by physically binding to the CTDSPL promoter region. Taken together, our data identified a novel feedback regulatory circuitry composed of miR-26a, GSK3β and C/EBPα, the function of which might contribute to the regulation of hADSC osteogenesis. Our findings provided new insights into the function of miR-26a and the mechanisms underlying osteogenesis of hADSCs.

Abstract
Cell-based therapy is a potential alternative to liver transplantation. The goal of the present study was to examine the in vivo and in vitro hepatic differentiation potential of adipose tissue-derived mesenchymal stem cells (AT-MSCs) and to explore its therapeutic use. AT-MSCs were isolated and cultured with hepatic differentiation medium. Bioactivity assays were used to study the properties of AT-MSCs. The morphology of differentiated AT-MSCs in serum-free hepatic differentiation medium changed into polygonal epithelial cells, while the morphology of AT-MSCs in a similar medium containing 2% fetal bovine serum remained unchanged. The differentiated cells cultured without serum showed hepatocyte-like cell morphology and hepatocyte-specific markers, including albumin (ALB) and α-fetoprotein. The bioactivity assays revealed that hepatocyte-like cells could take up low-density lipoprotein (LDL) and store glycogen. Furthermore, trichostatin A (TSA) enhanced ALB production and LDL uptake by the hepatocyte-like cells, analogous to the functions of human liver cells. ALB was detected in the livers of the CCl4-injured mice one month post-transplantation. This suggested that transplantation of the human AT-MSCs could relieve the impairment of acute CCl4-injured livers in nude mice. This therefore implied that adipose tissue was a source of multipotent stem cells which had the potential to differentiate into mature, transplantable hepatocyte-like cells in vivo and in vitro. In addition, the present study determined that TSA was essential to promoting differentiation of human MSC towards functional hepatocyte-like cells. The relief of liver injury following treatment with AT-MSCs suggested their potential as a novel therapeutic method for liver disorders or injury.

Abstract
The role of C-X-C chemokine receptor type 4 (CXCR4) in umbilical mesenchymal stem cells (UMSCs) as therapy for liver disease is ill understood. The aim of the study was to evaluate rat UMSCs (rUMSCs) on CXCR4 expression and homing to injured liver tissue. rUMSCs were isolated from umbilical cords of pregnant rats. Acute liver failure (ALF) models were developed using D-galactosamine. CXCR4 expression induction by serum from rats with ALF (LFS), cytokines, growth factors, and LPS was analyzed. CXCR4 expression was analyzed by RT-PCR, western blot, and flow cytometry. rUMSCs were labeled with carboxyfluorescein and pretreated with LFS to induce CXCR4 expression and were transplanted into ALF rats. Animals were sacrificed 48 h and 1 week after transplantation. Liver-homing rUMSCs were observed under fluorescence microscopy. rUMSCs were successfully isolated, expressing CD90 and CD106, but not CD34 and CD45. mRNA and protein expressions of CXCR4 were strongly up-regulated by LFS and by the mixture of cytokines, stem cell factor, and LPS (CM). Expression of cell surface CXCR4 on rUMSCs in groups treated with LFS (42.37 ± 1.60 %) and CM (40.17 ± 1.78 %) was higher than that in the untreated control group (9.67 ± 1.06 %) (both P < 0.001). At 48 h after transplantation, more rUMSCs pretreated with LFS appeared in the portal area, and migrated to the liver parenchyma after 1 week. LFS strongly induced the surface expression of CXCR4 on rUMSCs. Increasing CXCR4 expression on rUMSCs may enhance their homing ability to injured liver tissue, and may eventually be used for treating liver diseases.

Abstract
In this study, for the first time, a biodegradable poly(L-lactide-co-ε-caprolactone), PLC 67:33 copolymer was developed for use as temporary scaffolds in reconstructive nerve surgery. The effect of the surface topology and pore architecture were studied on the biocompatibility for supporting the growth of human umbilical cord Wharton's jelly-derived mesenchymal stem cells (hWJ-MSCs) and human neuroblastoma cells (hNBCs) as cell models. Porous PLC membranes were prepared by electrospinning and phase immersion precipitation with particulate leaching and nonporous PLC membranes were prepared by solvent casting. From the results, the porous PLC membranes can support hWJ-MSCs and hNBCs cells better than the nonporous PLC membrane, and the interconnected pore scaffold prepared by electrospinning exhibited a more significant supporting attachment of the cells than the open pore and nonporous membranes. We can consider that these electrospun PLC membranes with 3-D interconnecting fiber networks and a high porosity warrant a potential use as nerve guides in reconstructive nerve surgery.

Abstract
BACKGROUND AND OBJECTIVES With increasing use of mesenchymal stem cells (MSCs) in regenerative medicine, there is greater awareness towards the need to have clinical grade products. The bovine media currently used allow good expansion to give large number of MSCs of the right quality. This report brings the significance of using cord blood serum (CBS) in the derivation of MSCs from umbilical cord matrix, to help its clinical applicability. METHODS AND RESULTS MSCs isolated from the cord by explant cultures were expanded and characterized by flow cytometry. Cord blood serum while helping expansion, has the ability to preserve the immunophenotype and differentiation potential of the MSCs derived from the umbilical cords. CONCLUSIONS Our results suggest that MSCs derived and expanded in cord blood serum are better suited for clinical applications.

Abstract
Differentiation of mesenchymal stem cells (MSCs) to hepatocyte-like cells is associated with morphological and biological changes. In this study, the effect of hepatogenic differentiation on fatty acid profile and the expression of proliferator-activated receptors-α (PPAR-α) have been studied. For this purpose, MSCs isolated from human umbilical cord were differentiated into hepatocyte-like cells on selective culture media. The morphological and biochemical changes, PPAR-α expression and reactive oxygen species (ROS) levels were studied during the differentiation process. Besides, the cells were processed to determine changes in fatty acid profile using gas chromatography analysis. The results showed that hepatic differentiation of the MSCs is associated with a decrease in major polyunsaturated fatty acids in mature hepatocytes, whereas there was an increase in the saturated fatty acid (SFA) levels during hepatocyte maturation. The differentiation-dependent shift in the ratio of SFA/USFA was associated with changes in albumin and PPAR-α expression, whereas changes in fatty acid profile were independent of ROS production and lipid peroxidation in differentiating cells. In conclusion, these data may suggest that hepatocyte formation during the stem cell differentiation is associated with a shift in the fatty acid profile that is probably a normal phenomenon in hepatogenic differentiation of the MSCs.

Abstract
Exploring the molecular mechanisms that regulate the osteogenesis of human mesenchymal stem cells (hMSCs) will bring us more efficient methods for improving the treatment of bone-related diseases. In this study, we analyzed the effects of miR-31 on the osteogenesis of hMSCs. The overexpression of miR-31 repressed the osteogenesis of hMSCs, whereas the downregulation enhanced this process. SATB2 was testified to be a direct target of miR-31, and its effects on the osteogenesis were also described. Most importantly, the knockdown of SATB2 attenuated miR-31's osteogenic effects. Taken together, our findings suggest that miR-31 regulates the osteogenesis of hMSCs by targeting SATB2.

Abstract
Human mesenchymal stem cells (hMSCs) are multipotent cells used in cell therapy research. One of the problems involving hMSCs is the possibility of genetic instability during in vitro expansion required to obtain a suitable number of cells for clinical applications. The cytokinesis-block micronucleus (CBMN) assay measures genetic instability by analyzing the presence of micronucleus (MN), nucleoplasmic bridges (NPBs), and nuclear buds (NBUDs) in binucleated cells. The present study describes modifications in the CBMN assay methodology to analyze genetic instability in hMSCs isolated from the umbilical vein and in vitro expanded. The best protocol to achieve binucleated hMSCs with preserved cytoplasm was as follows: cytochalasin B concentration (4.0 μg/mL), use of hypotonic treatment (3 min), and the fixative solution (9 methanol:1 acetic acid). These adaptations were reproduced in three hMSC primary cell cultures and also in XP4PA and A549 cell lines. The frequency of hMSCs treated with mitomycin-C presenting MN was lower than that with other nuclear alterations, indicating that the hMSCs contain mechanisms to avoid a high level of chromosomal breaks. However, a high frequency of cells with NPBs was detected and spontaneous anaphase bridges under normal hMSC in vitro culture were observed. Considering that anaphase bridges are characteristic alterations in tumor cells, the CBMN assay is indicated as an important tool associated with other genetic analyses in order to ensure the safe clinical use of hMSCs in cell therapy.

Abstract
Umbilical cord blood mesenchymal stem cells (UCB-MSCs) transplantation is becoming a promising and attractive cell-based treatment modality for repairing the damaged central nervous system due to its advantages of low immunogenicity, wide range of sources, and less ethical controversy. One of the limitations of this approach is that the proportion of neurons differentiated from UCB-MSCs still remains at low level. Thus, to induce UCB-MSCs to differentiate into neuron-like cells with a higher proportion is one of the key technologies of regenerative medicine and tissue engineering. Many induction protocols with remarkably higher differentiation rate to neurons have been reported. However, each protocol has its pros and cons and whether the neurons differentiated from UCB-MSCs under a certain protocol has normal nerve function remains controversial. Therefore, to guarantee the success of future clinical applications of UCB-MSCs, more investigations should be performed to improve the induction method and differentiation efficiency.

Abstract
Once cartilage is damaged, it has limited potential for self-repair. Autologous chondrocyte implantation is an effective treatment, but patients may suffer during cartilage harvesting and the donor-site morbidity may accelerate joint degeneration. Using autologous mesenchymal stem cells (MSCs) derived chondrocytes is another selection, while it also causes some injuring. The umbilical cord, an ecto-embryo tissue may be an ideal source of cells, because of its accessibility, abundant resources, painless procedures for harvesting, and lack of ethical issues. We isolated MSCs from Wharton's jelly of human umbilical cord (WMSCs), which expressed CD44, CD105 and CD271 but not CD34 and CD45 with flow cytometry analysis. RT-PCR showed not only positive expression of CD90, c-kit, Sca1, SH2 and SH3 but also positive expression of the chondrocyte markers Sox-9 and Col-2A1. WMSCs cultured in high-density in the presence of transforming growth factor β1 and dexamethasone showed cartilage extracellular matrix-secretion and integrated into a thin piece of cell-based membrane. The cell-based thin membrane cultured in rotary cell culture system formed a round, opaque, glistening non-scaffold cartilage-like tissue, larger and condenser than what was formed with conventional pellet culture. Glycosaminoglycan and type II collagen content significantly increased after 3-week culture. The human WMSCs express characteristics of pre-chondrocytes, low immunogenicity and are easy to be obtained with higher purity because there have no hematopoietic cells in Wharton's jelly, so it may be a new seed cells more suitable for constructing tissue-engineered cartilage.

Abstract
INTRODUCTION The corneal stroma is being increasingly recognized as a repository for stem cells. Like the limbal and endothelial niches, stromal stem cells often reside in the peripheral cornea and limbus. These peripheral and limbal corneal stromal cells (PLCSCs) are known to produce mesenchymal stem cells in vitro. Recently, a common corneal stromal and epithelial progenitor was hinted at. This study aims to examine the stem cell potential of corneal stromal cells and to investigate their epithelial transdifferentiation ability. METHODS PLCSCs were grown in traditional Dulbecco modified Eagle medium (DMEM)-based keratocyte culture medium and an M199-based medium and analyzed for a profile of cell-surface markers by using flow cytometry and differentiated into mesenchymal phenotypes analyzed with quantitative polymerase chain reaction (qPCR) and histologic staining. PLCSCs in M199 were subsequently divided into subpopulations based on CD34 and CD105 expression by using fluorescence- activated cell sorting (FACS). Subpopulations were characterized by marker profile and mesenchymal differentiation ability. Both whole PLCSCs and subpopulations were also cultured for epithelial transdifferentiation. RESULTS Cells cultured in M199 demonstrated a more stem-like cell-surface marker profile, and the keratocyte marker CD34 was retained for several passages but absent in cells cultured in DMEM. Cells cultured in M199 also exhibited a greater mesenchymal differentiation potential, compared with DMEM. PLCSCs could be divided into CD34(+)CD105(+), CD34-CD105(+), and CD34-CD105- subpopulations, of which CD34(+)CD105(+) cells were the most stemlike with regard to marker expression and mesenchymal differentiation potential. Subpopulations of PLCSCs exhibited differing abilities to transdifferentiate into epithelial phenotypes. Cells that were initially CD34(+)CD105(+) showed the greatest differentiation potential, producing CK3(+) and CK19(+) cells, and expressed a range of both epithelial progenitor (HES1, FRZB1, DCT, SOD2, ABCG2, CDH1, KRT19) and terminally differentiated (DSG3, KRT3, KRT12, KRT24) genes. CONCLUSIONS Culture medium has a significant effect on the phenotype and differentiation capacity of PLCSCs. The stroma contains a heterogeneous cell population in which we have identified CD34(+) cells as a stem cell population with a capacity for mesenchymal and epithelial differentiation.

Abstract
Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) possess various advantageous properties, including self-renewal, extended proliferation potential, multi-lineage differentiation potential and capacity for differentiating into sweat gland-like cells in certain conditions. However, little is known about the effect of clinical-grade culture conditions on these properties and on the differentiative potential of hUC-MSCs. In this study, we sought to investigate the properties of hUC-MSCs expanded with animal serum free culture media (ASFCM) in order to determine their potential for differentiation into sweat gland-like cells. We found that primary cultures of hUC-MSCs could be established with ASFCM. Moreover, cells cultured in ASFCM showed vigorous proliferation comparable to those of cells grown in classical culture conditions containing fetal bovine serum (FBS). Morphology of hUC-MSCs cultured in ASFCM was comparable to those of cells grown under classical culture conditions, and hUC-MSCs grown in both of the two culture conditions tested showed the typical antigen profile of MSCs-positive for CD29, CD44, CD90, and CD105, and negative for CD34 and CD45, as expected. Chromosomal aberration assay revealed that the cells were stable after long-term culture under both culture conditions. Like normal cultured MSCs, hUC-MSCs induced under ASFCM conditions exhibited expression of the same markers (CEA, CK14 and CK19) and developmental genes (EDA and EDAR) that are characteristic of normal sweat gland cells. Taken together, our findings indicate that the classical culture medium used to differentiate hUC-MSCs into sweat gland-like cells can be replaced safely by ASFCM for clinical purposes.

Abstract
Multilineage-differentiating stress-enduring (Muse) cells are distinct stem cells in mesenchymal cell populations with the capacity to self-renew, to differentiate into cells representative of all three germ layers from a single cell, and to repair damaged tissues by spontaneous differentiation into tissue-specific cells without forming teratomas. We describe step-by-step procedures for isolating and evaluating these cells. Muse cells are also a practical cell source for human induced pluripotent stem (iPS) cells with markedly high generation efficiency. They can be collected as cells that are double positive for stage-specific embryonic antigen-3 (SSEA-3) and CD105 from commercially available mesenchymal cells, such as adult human bone marrow stromal cells and dermal fibroblasts, or from fresh adult human bone marrow samples. Under both spontaneous and induced differentiation conditions, they show triploblastic differentiation. It takes 4-6 h to collect and 2 weeks to confirm the differentiation and self-renewal capacity of Muse cells.

Abstract
OBJECTIVE To identify and quantitatively determine Mesenchymal stem cells (MSCs) in the umbilical cord blood (UCB) of neonates born at different gestational periods. METHODS UCB was collected at birth in neonates of three different gestational groups. The mononuclear cells (MNCs) were phenotypically analyzed by flow cytometer. RESULTS The yield of total MNCs did not differ much with gestation; the average values were 22.6 ± 6.48 × 106 cells/ml. The MSCs were significantly higher in the lower gestation group. These were 0.0219 ± 0.012 %, 0.0044 ± 0.003 % and 0.0022 ± 0.003 % in 28 to 31 wk, 32 to 35 wk and >36 wk, respectively (P = 0.00). There was a significant inverse correlation between the gestational age and the presence of MSCs with a correlation co-efficient of -0.54 (P = 0.0001). CONCLUSIONS The MSCs population was significantly higher in infants born at lesser gestation than those born at term gestation.

Abstract
Dopaminergic (DA) neuron therapy has been established as a new clinical tool for treating Parkinson's disease (PD). Prior to cell transplantation, there are two primary issues that must be resolved: one is the appropriate seed cell origin, and the other is the efficient inducing technique. In the present study, human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) were used as the available seed cells, and conditioned medium from human amniotic epithelial cells (ACM) was used as the inducing reagent. Results showed that the proportion of DA neuron-like cells from hUCB-MSCs was significantly increased after cultured in ACM, suggested by the upregulation of DAT, TH, Nurr1, and Pitx3. To identify the process by which ACM induces DA neuron differentiation, we pretreated hUCB-MSCs with k252a, the Trk receptor inhibitor of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), and found that the proportion of DA neuron-like cells was significantly decreased compared with ACM-treated hUCB-MSCs, suggesting that NGF and BDNF in ACM were involved in the differentiation process. However, we could not rule out the involvement of other unidentified factors in the ACM, because ACM + k252a treatment does not fully block DA neuron-like cell differentiation compared with control. The transplantation of ACM-induced hUCB-MSCs could ameliorate behavioral deficits in PD rats, which may be associated with the survival of engrafted DA neuron-like cells. In conclusion, we propose that hUCB-MSCs are a good source of DA neuron-like cells and that ACM is a potential inducer to obtain DA neuron-like cells from hUCB-MSCs in vitro for an ethical and legal cell therapy for PD.

Abstract
Cirrhosis is a serious threat to human health. Currently, there have been no available radical measures that can effectively block the process of this disease. The research progress in the field of stem cells brings an opportunity for the treatment of cirrhosis. Having a wide variety of sources, weak immunogenicity, and strong proliferation and differentiation ability, human umbilical cord blood-derived mesenchymal stem cells have been demonstrated to be promising in the treatment of liver cirrhosis. This article reviews the biological characteristics of human umbilical cord blood mesenchymal stem cells and their application in the treatment of cirrhosis.

Abstract
INTRODUCTION Hyaline articular cartilage is the connective tissue responsible for frictionless joint movement. Its degeneration ultimately results in complete loss of joint function in the late stages of osteoarthritis. Intrinsic repair is compromised, and cartilage tissue regeneration is difficult. However, new options are available to repair cartilage tissue by applying ESCs, MSCs and CPCs. AREAS COVERED In this review, the authors shed light on the different concepts currently under investigation for cartilage repair. EXPERT OPINION So far, there is no way to derive a chondrogenic lineage from stem cells that forms functional hyaline cartilage tissue in vivo. One alternative might be to enhance the chondrogenic potential of repair cells, which are already present in diseased cartilage tissue. CPCs found in diseased cartilage tissue in situ are biologically driven toward the osteochondrogenic lineage and can be directed toward chondrogenesis at least in vitro.

[PMID: 23041512 DOI: 10.1016/j.neuroscience.2012.09.066] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2012] [Revised: 09/25/2012] [Accepted: 09/26/2012] [Indexed: 12/18/2022]
Abstract
Human umbilical cord blood cells (HUCBCs) have been employed as a restorative treatment for experimental stroke. In this study, we investigated whether transplantation of sub-therapeutic doses of HUCBCs and Simvastatin enhances cerebral vascular remodeling after stroke. Adult male Wistar rats (n=34) were subjected to transient middle cerebral artery occlusion (MCAo) and treated with: phosphate-buffered solution (PBS, gavaged daily for 7 days); Simvastatin (0.5mg/kg, gavaged daily for 7 days); HUCBCs (1×10(6), injected once via tail vein); and combination Simvasatin with HUCBCs, starting at 24h after MCAo. There was no significant difference between Simvastatin- or HUCBC-monotherapy and MCAo-alone group. Combination treatment 24h post-stroke significantly increased the perimeter of von Willebrand factor (vWF)-positive vessels, the diameter and density of alpha smooth muscle actin (αSMA)-positive arteries, and the percentage of 5-bromodeoxyuridine (BrdU)-positive endothelial cells (ECs) in the ischemic boundary zone (IBZ) compared with MCAo-alone or HUCBC-monotherapy 14 days after MCAo (p<0.05, n=8/group); Combination treatment significantly increased the densities of vWF-vessels and αSMA-arteries as well as the densities of BrdU-ECs and BrdU-positive smooth muscle cells (SMCs) in vascular walls in the IBZ compared with Simvastatin-monotherapy. Moreover, the increased BrdU-ECs and BrdU-SMCs were significantly correlated with neurological functional outcome 14 days after MCAo. Combination treatment also significantly increased the expression of Angiopoietin-1 (Ang1), Tie2 and Occludin in the IBZ (p<0.05, n=8/group). The in vitro experiments showed that combination treatment and Ang1 significantly increased capillary-like tube formation and arterial cell migration; anti-Ang1 significantly reduced combination treatment-induced tube-formation and artery cell migration (p<0.05, n=6/group). These findings indicated that a combination of sub-therapeutic doses of Simvastatin and HUCBCs treatment of stroke increases Ang1/Tie2 and Occludin expression in the ischemic brain, amplifies endogenous angiogenesis and arteriogenesis, and enhances vascular remodeling which in concert may contribute to functional outcome after stroke.

Abstract
It is unknown whether human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) can improve the renal function of patients suffering from acute kidney injury. Moreover, before beginning clinical trials, it is necessary to investigate this renoprotective effect of hUC-MSCs in a xenogeneic model of acute kidney injury. However, no previous studies have examined the application of hUC-MSCs to immunodeficient mice suffering from acute kidney injury. The objectives of this study were to examine whether hUC-MSCs could improve renal function in nonobese diabetic-severe combined immune deficiency (NOD-SCID) mice suffering from acute kidney injury, and to investigate the mechanism(s) for hUC-MSCs to improve renal function in this xenogeneic model. Early (3 hr) and late (12 hr) administrations of hUC-MSCs (106 cells) were performed via the external jugular vein into NOD-SCID mice suffering from either folic acid (FA) (250 mg/kg body weight) or vehicle. The results showed that early administration of hUC-MSCs improved the renal function of NOD-SCID mice suffering from FA-induced acute kidney injury, as evidenced by decreased serum urea nitrogen and serum creatinine levels, as well as a reduced tubular injury score. The beneficial effects of hUC-MSCs were through reducing apoptosis and promoting proliferation of renal tubular cells. These benefits were independent of inflammatory cytokine effects and transdifferentiation. Furthermore, this study is the first one to show that the reduced apoptosis of renal tubular cells by hUC-MSCs in this xenogeneic model is mediated through the mitochondrial pathway, and through the increase of Akt phosphorylation.

Abstract
AIMS To conduct a morphological, functional and chromosomal characterization of mesenchymal stem cell populations from the human subendothelium umbilical cord vein after cryopreservation. MATERIAL & METHODS Five human umbilical cords were processed in order to obtain mesenchymal stem cells. Flow cytometry, differentiation assays and cytogenetic analysis were carried out before and after the cryopreservation process. RESULTS Flow cytometry revealed that CD105, CD73 and CD90 markers were expressed by the cells, which lacked the expression of hematopoietic lineage markers, such as CD14, CD34 and CD45. The mesenchymal stem cells demonstrated capacity for osteogenic, adipogenic and chondrogenic differentiation. Chromosome analysis showed no clonal chromosome changes in the cells in either situation. However, a significant number of nonclonal chromosomal aberrations were apparent after cryopreservation, including monosomies and structural changes. Cells isolated from one umbilical cord exhibited a rare balanced paracentric inversion, likely a cytogenetic constitutional alteration. This was present both before and after experimental procedures. CONCLUSION These findings show that using mesenchymal stem cells for clinical approaches requires careful investigation and sensitive tests in order to ensure cellular therapy biosafety.

Abstract
Many common diseases involve the injury, loss, or death of organ tissues. For these patients, organ transplantation is often the only viable solution. Nonetheless, organ transplantation is seriously limited by the relative scarcity of living and non-living donors, a situation that is worsening with aging of the world population. Tissue Engineering (TE) is a research discipline in regenerative medicine that aims to generate tissues in the laboratory that can replace diseased and damaged tissues in patients. Crucially, engineered tissues must have a vascular network that guarantees adequate nutrient supply, gas exchange, and elimination of waste products. Therefore, the search for clinically relevant sources of vasculogenic cells and the subsequent development of methods to achieve rapid vascularization is of utmost importance. We and others have previously shown that human blood-derived endothelial colony-forming cells (ECFCs) have the required vasculogenic capacity to form functional vascular networks in vivo. These studies demonstrated that, in the presence of an appropriate source of perivascular cells, ECFCs can self-assemble into microvascular networks and connect to the host vasculature, a process that takes approximately 7days in vivo. The prospect is to incorporate these vascular networks into future engineered tissues. However, engineered tissues must have a functional vasculature immediately after implantation in order to preserve viability and function. Thus, it is critical to further develop strategies for rapid formation of perfused vascular network in vivo. Here, we describe a methodology to deliver ECFCs and bone marrow-derived mesenchymal stem cells (MSCs) subcutaneously into immunodeficient mice in the presence of fibroblast growth factor-2 (FGF-2). This approach significantly reduces the time needed to achieve functional anastomoses between bioengineered human blood vessels and the host vasculature. This methodology includes (1) isolation, characterization and culture of ECFCs, (2) isolation, characterization and culture of MSCs, and (3) implantation of ECFCs and MSCs, in the presence of FGF-2, into immunodeficient mice to generate perfused vascular networks.

Abstract
Mesenchymal cell populations, referred to as mesenchymal stem cells or multipotent stromal cells (MSCs), which include bone marrow stromal cells (BMSCs), umbilical cord stromal cells and adipose stromal cells (ASCs), participate in tissue repair when transplanted into damaged or degenerating tissues. The trophic support and immunomodulation provided by MSCs can protect against tissue damage, and the differentiation potential of these cells may help to replace lost cells. MSCs are easily accessible and can be expanded on a large scale. In addition, BMSCs and ASCs can be harvested from the patient himself. Thus, MSCs are considered promising candidates for cell therapy. In this review, I will discuss recently discovered high-efficiency induction systems for deriving Schwann cells and neurons from MSCs. Other features of MSCs that are important for tissue repair include the self-renewing property of stem cells and their potential for differentiation. Thus, I will also discuss the stemness of MSCs and describe the discovery of a certain stem cell type among adult MSCs that can self-renew and differentiate into cells of all three germ layers. Furthermore, I will explore the prospects of using this cell population for cell therapy.

Abstract
The emerging fields of tissue engineering and biomaterials have begun to provide potential treatment options for liver failure. The goal of the present study is to investigate the ability of a poly L-lactic acid (PLLA) nanofiber scaffold to support and enhance hepatic differentiation of human bone marrow-derived mesenchymal stem cells (hMSCs). A scaffold composed of poly L-lactic acid and collagen was fabricated by the electrospinning technique. After characterizing isolated hMSCs, they were seeded onto PLLA nanofiber scaffolds and induced to differentiate into a hepatocyte lineage. The mRNA levels and protein expression of several important hepatic genes were determined using RT-PCR, immunocytochemistry and ELISA. Flow cytometry revealed that the isolated bone marrow-derived stem cells were positive for hMSC-specific markers CD73, CD44, CD105 and CD166 and negative for hematopoietic markers CD34 and CD45. The differentiation of these stem cells into adipocytes and osteoblasts demonstrated their multipotency. Scanning electron microscopy showed adherence of cells in the nanofiber scaffold during differentiation towards hepatocytes. Our results showed that expression levels of liver-specific markers such as albumin, α-fetoprotein, and cytokeratins 8 and 18 were higher in differentiated cells on the nanofibers than when cultured on plates. Importantly, liver functioning serum proteins, albumin and α-1 antitrypsin were secreted into the culture medium at higher levels by the differentiated cells on the nanofibers than on the plates, demonstrating that our nanofibrous scaffolds promoted and enhanced hepatic differentiation under our culture conditions. Our results show that the engineered PLLA nanofibrous scaffold is a conducive matrix for the differentiation of MSCs into functional hepatocyte-like cells. This represents the first step for the use of this nanofibrous scaffold for culture and differentiation of stem cells that may be employed for tissue engineering and cell-based therapy applications.

Abstract
The use of tendon-derived stem cells (TDSCs) as a cell source for musculoskeletal tissue engineering has not been compared with that of bone marrow stromal cells (BMSC). This study compared the mesenchymal stem cell (MSC) and embryonic stem cells (ESC) markers, clonogenicity, proliferative capacity, and multilineage differentiation potential of rat TDSC and BMSC in vitro. The MSC and ESC marker profiles of paired TDSC and BMSC were compared using flow cytometry and quantitative real-time polymerase chain reaction (qRT-PCR), respectively. Their clonogenicity and proliferative capacity were compared using colony-forming and 5-bromo-2'-deoxyuridine assays, respectively. The expression of tenogenic, osteogenic, and chondrogenic markers at basal state were examined using qRT-PCR. Their osteogenic, chondrogenic, and adipogenic differentiation potentials were compared using standard assays. TDSC and BMSC showed similar expression of CD90 and CD73. TDSC expressed higher levels of Oct4 than BMSC. TDSC exhibited higher clonogenicity, proliferated faster, and expressed higher tenomodulin, scleraxis, collagen 1 α 1 (Col1A1), decorin, alkaline phosphatase, Col2A1, and biglycan messenger RNA levels than BMSC. There was higher calcium nodule formation and osteogenic marker expression in TDSC than BMSC upon osteogenic induction. More chondrocyte-like cells and higher glycosaminoglycan deposition and chondrogenic marker expression were observed in TDSC than BMSC upon chondrogenic induction. There were more oil droplets and expression of an adipogenic marker in TDSC than BMSC upon adipogenic induction. TDSC expressed higher Oct4 levels, which was reported to positively regulate mesendodermal lineage differentiation, showed higher clonogenicity and proliferative capacity, and had greater tenogenic, osteogenic, chondrogenic, and adipogenic markers and differentiation potential than BMSC. TDSC might be a better cell source than BMSC for musculoskeletal tissue regeneration.

Abstract
This study aimed to compare clonogenicity, proliferation, stem cell-related marker expression, senescence, and differentiation potential of rat patellar tendon-derived stem cells (TDSCs) at early (P5), mid (P10), and late (P20, P30) passages. The clonogenicity of the cells was assessed by colony-forming assay and their proliferative potential was assessed by bromodeoxyuridine assay. The surface expression of CD90 and CD73 was assessed by flow cytometry. The cellular senescence was assessed by β-galactosidase activity. The adipogenic, chondrogenic, and osteogenic differentiation potentials of TDSCs were assessed by standard assays after induction. The mRNA expression of tendon-related markers, scleraxis (Scx) and tenomodulin (Tnmd), was measured by quantitative real-time reverse transcription-polymerase chain reaction. Both the colony numbers and proliferative potential of TDSCs increased with passaging. Concomitantly, there was significant upregulation of β-galactosidase activity with TDSC passaging. The subculture of TDSCs downregulated the expression of CD90 and CD73. Lipid droplets were formed in the early and mid passages of TDSCs upon adipogenic induction, but were absent in the late passages. The expression of peroxisome proliferator activator receptor gamma 2 (PPARγ2) and CCAAT/enhancer binding protein alpha (C/EBPα) in TDSCs after adipogenic induction decreased with passaging. Chondrogenesis, proteoglycan deposition, collagen type II protein expression, collagen type 2A1 (Col2AI), and aggrecan (Acan) mRNA expression were less in pellets formed with later passages of TDSCs after chondrogenic induction. The expression of Scx and Tnmd was lower in the late, compared with early and mid, passages of TDSCs. However, matrix mineralization and expression of alkaline phosphatase (Alpl) and osteocalcin (Bglap) mRNA after osteogenic induction increased with TDSC passaging. Researchers and clinicians should consider the changes of stem cell-related properties of TDSCs when multiplying them in vitro for tissue engineering.

Abstract
Multipotent mesenchymal stromal cells (MSCs) hold tremendous promise for tissue engineering and regenerative medicine, yet with so many sources of MSCs, what are the primary criteria for selecting leading candidates? Ideally, the cells will be multipotent, inexpensive, lack donor site morbidity, donor materials should be readily available in large numbers, immunocompatible, politically benign and expandable in vitro for several passages. Bone marrow MSCs do not meet all of these criteria and neither do embryonic stem cells. However, a promising new cell source is emerging in tissue engineering that appears to meet these criteria: MSCs derived from Wharton's jelly of umbilical cord MSCs. Exposed to appropriate conditions, umbilical cord MSCs can differentiate in vitro along several cell lineages such as the chondrocyte, osteoblast, adipocyte, myocyte, neuronal, pancreatic or hepatocyte lineages. In animal models, umbilical cord MSCs have demonstrated in vivo differentiation ability and promising immunocompatibility with host organs/tissues, even in xenotransplantation. In this article, we address their cellular characteristics, multipotent differentiation ability and potential for tissue engineering with an emphasis on musculoskeletal tissue engineering.

Abstract
The role of umbilical cord blood (CB)-derived stem cell therapy in neonatal lung injury remains undetermined. We investigated the capacity of human CB-derived CD34(+) hematopoietic progenitor cells to regenerate injured alveolar epithelium in newborn mice. Double-transgenic mice with doxycycline (Dox)-dependent lung-specific Fas ligand (FasL) overexpression, treated with Dox between embryonal day 15 and postnatal day 3, served as a model of neonatal lung injury. Single-transgenic non-Dox-responsive littermates were controls. CD34(+) cells (1 × 10(5) to 5 × 10(5)) were administered at postnatal day 5 by intranasal inoculation. Engraftment, respiratory epithelial differentiation, proliferation, and cell fusion were studied at 8 weeks after inoculation. Engrafted cells were readily detected in all recipients and showed a higher incidence of surfactant immunoreactivity and proliferative activity in FasL-overexpressing animals compared with non-FasL-injured littermates. Cord blood-derived cells surrounding surfactant-immunoreactive type II-like cells frequently showed a transitional phenotype between type II and type I cells and/or type I cell-specific podoplanin immunoreactivity. Lack of nuclear colocalization of human and murine genomic material suggested the absence of fusion. In conclusion, human CB-derived CD34(+) cells are capable of long-term pulmonary engraftment, replication, clonal expansion, and reconstitution of injured respiratory epithelium by fusion-independent mechanisms. Cord blood-derived surfactant-positive epithelial cells appear to act as progenitors of the distal respiratory unit, analogous to resident type II cells. Graft proliferation and alveolar epithelial differentiation are promoted by lung injury.

Abstract
Spinal cord injury (SCI) develops primary and secondary damage to neural tissue and this often results in permanent disability of the motor and sensory functions. However, there is currently no effective treatment except methylprednisolone, and the use of methylprednisolone has also been questioned due to its moderate efficacy and the drug's downside. Regenerative medicine has remarkably developed since the discovery of stem cells, and many studies have suggested the potential of cell-based therapies for neural injury. Especially, the therapeutic potential of human umbilical cord blood cells (hUCB cells) for intractable neurological disorders has been demonstrated using in vitro and vivo models. The hUCB cells are immune naïve and they are able to differentiate into other phenotypes, including the neural lineage. Their ability to produce several neurotropic factors and to modulate immune and inflammatory reactions has also been noted. Recent evidence has emerged suggesting alternative pathways of graft-mediated neural repair that involve neurotrophic effects. These effects are caused by the release of various growth factors that promote cell survival, angiogenesis and anti-inflammation, and this is all aside from a cell replacement mechanism. In this review, we present the recent findings on the stemness properties and the therapeutic potential of hUCB as a safe, feasible and effective cellular source for transplantation in SCI. These multifaceted protective and restorative effects from hUCB grafts may be interdependent and they act in harmony to promote therapeutic benefits for SCI. Nevertheless, clinical studies with hUCB are still rare because of the concerns about safety and efficiency. Among these concerns, the major histocompatibility in allogeneic transplantation is an important issue to be addressed in future clinical trials for treating SCI.
