Abstract
OBJECTIVE The purpose of this study was to explore the therapeutic characteristics of mesenchymal stem cells generated from human umbilical cord (hUC-MSCs) when utilized in conjunction with auto-crosslinked hyaluronic acid gel (HA-gel) for the management of intrauterine adhesion (IUA). The goal was to see how this novel therapy could enhance healing and improve outcomes for IUA patients. METHODS In this study, models of intrauterine adhesion (IUA) were established in Sprague-Dawley (SD) rats, which were then organized and divided into hUC-MSCs groups. The groups involved: hUC-MSCs/HA-gel group, control group, and HA-gel group. Following treatment, the researchers examined the uterine cavities and performed detailed analyses of the endometrial tissues to determine the effectiveness of the interventions. RESULTS The results indicated that in comparison with to the control group, both HA-gel, hUC-MSCs, and hUC-MSCs/HA-gel groups showed partial repair of IUA. However, in a more notable fashion transplantation of hUC-MSCs/HA-gel complex demonstrated significant dual repair effects. Significant outcomes were observed in the group treated with hUC-MSCs and HA-gel, they showed thicker endometrial layers, less fibrotic tissue, and a higher number of endometrial glands. This treatment strategy also resulted in a significant improvement in fertility restoration, indicating a profound therapeutic effect. CONCLUSIONS The findings of this study suggest that both HA-gel, hUC-MSCs, and hUC-MSCs/HA-gel complexes have the potential for partial repair of IUA and fertility restoration caused by endometrium mechanical injury. Nonetheless, the transplantation of the hUC-MSCs/HA-gel complex displayed exceptional dual healing effects, combining effective anti-adhesive properties with endometrial regeneration stimuli.

Abstract
Human umbilical cord-derived mesenchymal stem cells (hucMSCs) can differentiate into multiple cell lineages, but few methods have been developed to generate kidney lineage cells. Due to their human origin, pluripotent nature and immunomodulatory properties, these stem cells are attractive candidates for clinical applications such as the repair or regeneration of damaged organs. This study evaluated the renal differentiation potential of hucMSCs, when exposed for 10 days to optimised concentrations of retinoic acid, activin-A and bone morphogenetic protein-7 (BMP-7) in various combinations, with and without the priming of the cells with a Wnt signalling pathway activator (CHIR99021). The hucMSCs were isolated and characterised according to surface marker expression (CD73, CD90, CD44, CD146 and CD8) and tri-lineage differentiation potential. The expression of key marker genes (OSR1, TBXT, HOXA13, SIX2, PAX2, KRT18 and ZO1) was examined by qRT-PCR. Specific marker protein expression (E-cadherin, cytokeratin-8 and cytokeratin-19) was analysed by immunocytochemistry. CHIR99021-primed cells treated with the retinoic acid, activin-A and BMP-7 cocktail showed epithelial cell-like differentiation - i.e. distinct phenotypic changes, as well as upregulated gene and protein expression, were observed that were consistent with an epithelial cell phenotype. Thus, our results showed that hucMSCs can efficiently differentiate into renal epithelial-like cells. This work may help in the development of focused therapeutic strategies, in which lineage-defined human stem cells can be used for renal regeneration.

Abstract
Diabetic foot ulcer (DFU) is a main diabetic complication with unmet treatment needs. This study applied human umbilical cord-derived mesenchymal stem cells-hyaluronic acid (hucMSCs-HA) gel to treat DFU in a noninvasive external way and investigated its paracrine action and mechanism. In this study, after analyzing the physical and biological properties of HA gel, hucMSCs-HA gel was applied in 2 in vivo models (types I and II DFU), and a molecular mechanism was investigated. To evaluate the paracrine action of hucMSCs, hucMSCs-conditional medium (MSC-CM) was collected to treat 1 in vivo model (type I DFU) and 2 in vitro models (high glucose (HG)-injured human umbilical vein endothelial cells (HUVECs) and human skin fibroblasts (HSFs)). The results indicated that HA gel with a porous microstructure underwent over 90% degradation and swelled to the maximum value within 48 h. In vivo, hucMSCs-HA gel accelerated wound healing of DFU rats by improving re-epithelialization, collagen deposition, and angiogenesis, in which a paracrine action of hucMSCs was confirmed and the phosphorylation of p38, ERK1/2, JNK, and Akt was increased. In vitro, MSC-CM improved cell viability, wound healing, migration, tube formation, cell senescence, and abnormal expressions (TNF-α, IL-1β, IL-6, ET-1, p16 genes, and PCNA protein) of HUVECs, also improved cell viability, wound healing, antioxidant stress, and abnormal expressions (COL1, COL3, COL4, SOD1, SOD2 genes, and PCNA protein) of HSFs. Summarily, noninvasive external application of hucMSCs-HA gel shows great perspective against DFU and exerts wound healing effects through the MAPK and Akt pathways-mediated paracrine mechanism.

Abstract
Background Mesenchymal stem cells (MSCs) are multipotent stromal cells that have been reported to possess great potential for the treatment of bronchopulmonary dysplasia (BPD). Objective Our study aims to assess the effects of three different doses of intraperitoneal administration of human umbilical cord-derived MSCs (hUC-MSCs) on a hyperoxia-induced BPD model of newborn rat. Methods Neonatal Sprague Dawley (SD) rats were reared in either hyperoxia (75% O2) or room air (RA) from postnatal days (PN) 1-14. At PN5, hUC-MSCs (1 × 106, 5× 106,or 1× 107 cells per pup) were given intraperitoneally to newborn rats exposed to 75% O2 from birth; the controls received an equal volume of normal saline (NS). At PN14, the lung tissues, serum, and bronchoalveolar fluid (BALF) were collected for histologic examination, wet/dry (W/D) weight ratio analysis, engraftment, myeoloperoxidase (MPO) activity analysis, cytokine analysis, and western blot analysis of protein expression. Results Compared to rat pups reared in RA, rat pups reared in hyperoxia had a significant lower survival rate (53.3%) (P < 0.01). Hyperoxia-exposed rats exhibited pulmonary inflammation accompanied by alveolar-capillary leakage, neutrophile infiltration, augmented myeloperoxidase (MPO) activity, prominent alveolar simplification, and increased mean linear intercept (MLI), which was ameliorated by hUC-MSCs treatment. Increased oxidative stress and inflammatory cytokine production were also reduced. Importantly, the expression of Fas, an apoptosis-associated protein that was increasingly expressed in hyperoxia-exposed rats (P < 0.05), was downregulated after administration of hUC-MSCs (P < 0.05). Conclusions Our results suggest that intraperitoneal administration of high number hUC-MSCs (1 × 107 cells) may represent an effective modality for the treatment of hyperoxia-induced BPD in neonatal rats.

Abstract
Diabetic foot ulceration is a common chronic diabetic complication. Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) have been widely used in regenerative medicine owing to their multipotency and easy availability. We developed poly(lactic-co-glycolic acid) (PLGA)-based scaffold to create hUC-MSC tissue sheets. In vitro immunostaining showed that hUC-MSC tissue sheets formed thick and solid tissue sheets with an abundance of extracellular matrix (ECM). Diabetic wounds in mice treated with or without either the hUC-MSC tissue sheet, hUC-MSC injection, or fiber only revealed that hUC-MSC tissue sheet transplantation promoted diabetic wound healing with improved re-epithelialization, collagen deposition, blood vessel formation and maturation, and alleviated inflammation compared to that observed in other groups. Taken collectively, our findings suggest that hUC-MSCs cultured on PLGA scaffolds improve diabetic wound healing, collagen deposition, and angiogenesis, and provide a novel and effective method for cell transplantation, and a promising alternative for diabetic skin wound treatment.

Abstract
Background Fighting skin aging signs is one of the major challenges of the 21st century, recently, mesenchymal stem cells (MSCs) and microneedling (MN) have been applied for anti-aging. This study aims to evaluate the efficacy of the combination of MN and human umbilical cord-derived mesenchymal stem cells conditioned media (hUC-MSCs-CM) in skin brightness and rejuvenation. Methods Thirty volunteers with facial skin aging were recruited for the randomized, controlled split-face study. The left and right sides of the face were randomly applied with saline via MN or hUC-MSCs-CM via MN. Five sessions were performed for each volunteer at 2-week intervals. Two dermatologists evaluated the clinical improvement, in terms of skin brightness and texture. A satisfaction score based on a self-evaluation questionnaire was recorded at 2 weeks after the last treatment. The objective evaluation was recorded before the first treatment, and at 2 weeks after the last treatment. Results Twenty-eight volunteers with a mean (SD) age of 41 (6.54) years old completed the trial. The investigator’s assessment for skin brightness and texture, and the self-satisfaction score revealed statistically better effects in hUC-MSCs-CM -plus-MN group than in MN alone (MN saline) group. No severe side effects were reported during the whole study period. Compared to MN alone group, the objective assessment revealed significant improvements in skin brightness (reduced melanin index, ultraviolet spots, and brown spots) and skin texture (reduced wrinkles and pores, and increased skin elasticity) in hUC-MSCs-CM-plus-MN group, while there were no obvious differences in skin hydration, trans-epidermal water loss, and the erythema index. Conclusion The combination of hUC-MSCs-CM and MN exhibite anti-aging efficacy, and this could be used for facial rejuvenation in the future.

Abstract
Introduction Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) and their small extracellular vesicles (hUC-MSC-sEVs) have shown attractive prospects applying in regenerative medicine. This study aimed to compare the therapeutic effects of two agents on osteoarthritis (OA) and investigate underlying mechanism using proteomics. Methods In vitro, the proliferation and migration abilities of chondrocytes treated with hUC-MSCs or hUC-MSC-sEVs were detected by Cell Counting Kit-8 assay and scratch wound assay. In vivo, hUC-MSCs (a single dose of 5 × 105) or hUC-MSC-sEVs (30 μg/time) were injected into the knee joints of anterior cruciate ligament transection-induced OA model. Hematoxylin and eosin, Safranin O/Fast Green staining were used to observe cartilage degeneration. The levels of cartilage matrix metabolic molecules (Collagen II, MMP13 and ADAMTS5) and macrophage polarization markers (CD14, IL-1β, IL-10 and CD206) were assessed by immunohistochemistry. Finally, proteomics analysis was performed to characterize the proteinaceous contents of two agents. Results In vitro data showed that hUC-MSC-sEVs were taken up by chondrocytes. A total of 15 μg/mL of sEVs show the greatest proliferative and migratory capacities among all groups. In the animal study, hUC-MSCs and hUC-MSC-sEVs alleviated cartilage damage. This effect was mediated via maintaining cartilage homeostasis, as was confirmed by upregulation of the COL II and downregulation of the MMP13 and ADAMTS5. Moreover, the M1 macrophage markers (CD14) were significantly reduced, while the M2 macrophage markers (CD206 and IL-10) were increased in the hUC-MSCs and hUC-MSC-sEVs relative to the untreated group. Mechanistically, we found that many proteins connected to cartilage repair were more abundant in sEVs. Notably, compared to hUC-MSCs, the upregulated proteins in sEVs were mostly involved in the regulation of immune effector process, extracellular matrix organization, PI3K-AKT signaling pathways, and Rap1 signaling pathway. Conclusion Our study indicated that hUC-MSC-sEVs protect cartilage from damage and many cartilage repair-related proteins are probably involved in the restoration process. These data suggest the promising potential of hUC-MSC-sEVs as a therapeutic agent for OA.

Abstract
AIM To evaluate therapeutic outcomes of human umbilical cord-derived mesenchymal stem cells (HUC-MSCs) treatment in patients with refractory uveitis. METHODS A retrospective and noncomparative review was performed on four patients with refractory uveitis from December 2013 to December 2017. HUC-MSCs were administered intravenously at a dose of 1×106 cells/kg. Clinical response, relapse rate, change of visual acuity, and other metrics were evaluated. RESULTS All four patients presented with responses to HUC-MSCs treatment, with three males and one female. The numbers of uveitis attacks per year after the HUC-MSCs treatment (0, 2, 0, 0 respectively) all decreased compared with the numbers before the treatment (3, 6, 4, 4 respectively). The oral steroid and immunosuppressive agents were tapered in all patients without recrudescence of ocular inflammation, and three patients discontinued their oral medicine at the last visit. The best corrected visual acuity (BCVA) of 3 patients was improved to varying degrees, and the BCVA of 1 patient remained at 20/20 (Snellen chart) from the first to the last consultation. CONCLUSION The study provides an effective therapy of HUC-MSCs in maintaining remission in patients affected by uveitis refractory to previous immunosuppressant treatments.

Abstract
Mesenchymal stem cell (MSC) transplantation may serve as an important treatment modality in chronic kidney disease (CKD); however, the underlying mechanisms remain unclear. Advanced oxidation protein products (AOPP) have been demonstrated to induce renal tubular epithelial cell (RTEC) injury via autophagy inhibition. Therefore, the present study was performed to investigate the role of human umbilical cord-derived MSCs (hUC-MSCs) in RTEC autophagy. AOPP-treated HK-2 cells were co-cultured with hUC-MSCs or treated with recombinant humanized hepatocyte growth factor (HGF). Western blotting was used to detect the levels of autophagy-and PI3K/AKT/mTOR signaling pathway-related proteins, and immunofluorescence staining was used to detect the levels of autophagy-related proteins. The HGF protein levels in HK-2 cells and the hUC-MSC co-culture system were measured. The cells were subsequently treated with tivantinib, an HGF competitive inhibitor, and the levels of autophagy-related proteins were detected. Microtubule-associated protein 1 light chain 3B (LC3B) II/LC3B I (LC3II/LC3I) and beclin 1 protein levels were increased, while p62, PI3K, phosphorylated (p)-AKT and the p-mTOR protein levels were decreased in AOPP-treated HK-2 cells co-cultured with hUC-MSC, compared with the group treated with AOPP only. Furthermore, HGF expression was increased in AOPP-treated HK-2 cells co-cultured with hUC-MSC, compared with the group treated with AOPP alone. When HGF activity was inhibited using tivantinib, these effects on LC3II/LC3I, beclin 1, p62, PI3K, p-AKT, and p-mTOR expression were partially reversed. Furthermore, the effects of tivantinib were reversed by Ly294002. In conclusion, the present study revealed that hUC-MSCs partially reversed AOPP-mediated inhibition of autophagy in HK-2 cells via secretion of HGF, indicating that hUC-MSCs may serve as a potential therapy for preventing the progression of CKD.

Abstract
Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) are promising for the treatment of Alzheimer's disease (AD). However, their low rate of migration and survival in the brain limit their clinical applicability. This study is designed to improve the therapeutic potential of hUC-MSCs by preincubating them with resveratrol, a natural polyphenol capable of regulating cell destiny. Herein, we demonstrate that resveratrol preincubation enhances the migration of hUC-MSCs in vitro, as well as their survival and homing into the hippocampus of AD mice in vivo. Moreover, resveratrol-primed MSCs were better able to inhibit amyloid-β peptide (Aβ) deposition, Tau hyperphosphorylation, and oxidative stress, all while improving learning and memory. Notably, we found that hUC-MSCs inhibited neuroinflammation by reacting with astrocytes and microglial cells and suppressing mitogen-activated protein kinases (MAPKs), extracellular signal kinases (ERK), p38 kinases (p38), and c-Jun N-terminal kinases (JNK) signaling pathways in the hippocampus of AD mice. Furthermore, resveratrol pretreatment enhanced these effects. Conclusively, the current study revealed that resveratrol preconditioning protected hUC-MSCs against the hostile microenvironment characteristic of AD and enhanced their viability and homing into the brain of AD mice. The use of resveratrol-pretreated hUC-MSCs is thereby proposed to be a promising therapy for AD.

Abstract
So far, there were no reports on circular RNA (circRNA) expression profiles in the differentiation of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) into cardiomyocyte-like cells induced by 5-aza. In this study, hUCMSCs were isolated from umbilical cords and induced with 5-aza for 14 days. Immunofluorescence staining, real-time reverse transcription polymerase chain reaction (RT-PCR), and western blot of cardiac troponin I and α-sarcomeric actin on hUCMSCs between Days 14 and 0 were performed. The expression profile of circRNAs was analyzed by microarray and validated with RT-PCR. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes analyses were performed to identify the functions of differentially expressed genes and related pathways. The connections between circRNAs and microRNAs were explored by using Cytoscape. The results showed that a total of 226 circRNAs were calculated as differentially expressed during the differentiation. Among them, 127 were upregulated and 99 were downregulated. We selected circRNAs that were upregulated by more than five-fold and downregulated by more than three-fold. Ultimately, 74 differentially expressed circRNAs that were highly conserved on Day 14 after induction compared to Day 0 were identified. Among them, 41 were upregulated and 33 were downregulated. Four upregulated circRNAs (circRNA_01536, circRNA_04411, circRNA_09169, and circRNA_09905) and four downregulated circRNAs (circRNA_00699, circRNA_01183, circRNA_01978, and circRNA_16804) were randomly confirmed by RT-PCR. GO analysis suggested a number of cell proliferation and differentiation related physiological processes and pathways, such as the Wnt signaling pathway and others. Network analysis uncovered three potential key circRNAs, that is, circRNA_05432, circRNA_08441, and circRNA_01536.

Abstract
Cell transplantation strategies represent a potential therapeutic approach towards repair of congenital vaginal agenesis. In this study, the efficacy and mechanisms of action of treatment with human umbilical cord-derived mesenchymal stem cells (UC-MSCs) on vaginal regeneration was explored. UC-MSC transplantation alone, small intestinal submucosal (SIS) grafting alone, and a combination of UC-MSC transplantation/SIS grafting were performed with a vaginal defect rat model. Histological analyses of tissue sections were subsequently performed. UC-MSCs promoted the recovery of keratinizing squamous epithelium and papillae to nearly the same levels as in normal tissue. Of the treatments tested, UC-MSC transplantation showed optimal performance in inhibiting collagen deposition and accelerating the synthesis of elastin to maintain tissue elasticity. UC-MSC treatment also increased Cyclin D1, Ki67, and CD31 expression as assessed by immunohistochemistry. We also investigated the effects of UC-MSC secretions on keratinocytes in a co-culture model. UC-MSCs significantly stimulated vaginal tissue repair by promoting vaginal epithelium regeneration via paracrine factors but not by exploiting their keratinocyte differentiation potential. Further, UC-MSCs facilitated epithelial cell viability and promoted cell cycle progression via the AKT/GSK3β/Cyclin D1 pathway. These results indicate that UC-MSC transplantation is a feasible approach for vaginal tissue regeneration.

Abstract
The majority of premalignant gastric lesions develop in the mucosa that has been modified by chronic inflammation. As components of the gastritis microenvironment, mesenchymal stem cells (MSCs) and macrophages are critically involved in the initiation and development of the chronic gastritis-associated gastric epithelial lesions/malignancy process. However, in this process, the underlying mechanism of macrophages interacting with MSCs, particularly the effect of macrophages on MSCs phenotype and function remains to be elucidated. The present study revealed that human umbilical cord-derived MSCs were induced to differentiate into cancer-associated fibroblasts (CAFs) phenotype by co-culture with macrophages (THP-1 cells) in vitro, and which resulted in gastric epithelial lesions/potential malignancy via epithelial-mesenchymal transition-like changes. The results of the present study indicated that macrophages could induce MSCs to acquire CAF-like features and a pro-inflammatory phenotype to remodel the inflammatory microenvironment, which could potentiate oncogenic transformation of gastric epithelium cells. The present study provides potential targets and options for inflammation-associated gastric cancer prevention and intervention.

Abstract
Preemptive treatment with mesenchymal stem cells (MSCs) can attenuate cisplatin-induced acute kidney injury (AKI). However, it is uncertain whether MSC treatment after the development of renal dysfunction prevents AKI progression or if MSC immunomodulatory properties contribute to MSC therapy. In this study, human umbilical cord blood (hUCB)-derived MSCs were used to compare the effects and mechanisms of early and late MSC therapy in a murine model. After cisplatin injection into C57BL/6 mice, hUCB-MSCs were administered on day 1 (early treatment) or day 3 (late treatment). With early treatment, cisplatin nephrotoxicity was attenuated as evidenced by decreased blood urea nitrogen (BUN) and reduced apoptosis and tubular injury scores on day 3 Early treatment resulted in downregulation of intrarenal monocyte chemotactic protein-1 and IL-6 expression and upregulation of IL-10 and VEGF expression. Flow cytometric analysis showed similar populations of infiltrated immune cells in both groups; however, regulatory T-cell (Treg) infiltration was 2.5-fold higher in the early treatment group. The role of Tregs was confirmed by the blunted effect of early treatment on renal injury after Treg depletion. In contrast, late treatment (at a time when BUN levels were 2-fold higher than baseline levels) showed no renoprotective effects on day 6 Neither the populations of intrarenal infiltrating immune cells (including Tregs) nor cytokine expression levels were affected by late treatment. Our results suggest that early MSC treatment attenuates renal injury by Treg induction and immunomodulation, whereas a late treatment (i.e., after the development of renal dysfunction) does not prevent AKI progression or alter the intrarenal inflammatory micromilieu.

Abstract
Four patients with chronic refractory immune thrombocytopenic purpura (ITP) received human umbilical cord-derived mesenchymal stem cells (hUC-MSCs). The hUC-MSC dose was 5×107 to 1×108. Complete remission (CR) was achieved in three patients in 12 months and one patient in 24 months. Three patients received the second hUC-MSC transplantation with the same dose. The median time between hUC-MSC transplantation and response was 12.5 days (range, 7–16). There were no severe adverse events during and post hUC-MSC transplantation. During follow-up (median, 17 months; range, 13–24) no other immunosuppressive drugs were used post-first hUC-MSCs transplantation. In conclusion, hUC-MSC transplantation is a reasonable salvage treatment in chronic refractory ITP. Prospective randomized large-scale clinical trials are needed to further elucidate the efficacy of hUC-MSCs transplantation therapy on ITP.

Abstract
The aim of the study was to examine treatment of cerebral hemorrhages with bone-marrow or human umbilical cord-derived mesenchymal stem cells (BMSCs or Hu-MSCs) and conventional surgical approaches, and determine and compare the effectiveness, feasibility, safety and reproducibility of each method. A retrospective analysis was performed on a cohort of cell-treated cerebral hemorrhage patients from October 1, 2007 to October 1, 2009. A total of 24 patients, all of whom received conventional surgical treatment, were classified as follows: i) The control group consisted of 8 patients who received only hematoma removal surgery, ii) the autologous group consisted of 7 patients who received additional autologous bone marrow mononuclear cell transplantation, and iii) the allograft group consisted of 9 patients who received additional umbilical cord mononuclear cell transplantation. After conventional hematoma removal surgery and X-ray supervision within 24 h and at 7 days, neurological disability and function tests were completed 3, 6, 12, 36 and 60 months later. The T-cell marker plasma levels were analyzed after 60 months. The results showed that, at approximately 3.5 months after graft the hematomas in all the groups were completely reabsorbed as observed on computed tomography scans. However, the functional outcomes in the cell-transplanted groups were better than in the control group after 5 years. While the National Institutes of Health Stroke Scale, modified Rankin score and modified Barthel index scores were simliar in the cell-transplanted groups, patients in the allograft group had better outcomes than those in the autologous graft group starting at 3 months and until the end of the follow-up period. The serum levels of T-cell markers CD4, CD56 and human leukocyte antigen-DR in the allograft group showed no signs of immunogenic graft complications and there were no significant differences in T-cell subtypes among the patient groups. The results of the present study suggest that, treatment of cerebral hemorrhage patients can be safely and effectively accomplished using Hu-MSC grafting and larger clinical trials should be considered in the future.

Abstract
Congestive heart failure (HF) is a leading cause of morbidity and mortality worldwide. Although advances in medical therapy, mechanical support and heart transplantation have been made, almost half of all patients with HF succumb to the disease within five years of the initial diagnosis. Therefore, treatment methods need to be identified to restore the structure and function of cardiac muscle. Three patients with HF caused by ischemic cardiomyopathy received human umbilical cord-derived mesenchymal stem cell (HUC-MSC) intravenous infusion were included in the present study. Two patients demonstrated a 65.1% increase in left ventricular ejection fraction (LVEF) at the end of 3 months, which was maintained increasing 47.8% at the end of 12 months post-HUC-MSC intravenous infusion. LVEF of patient 1 decreased slowly in the observation period. This LVEF improvement was associated with significant improvements in the clinical parameters of the New York Heart Association class, and six-minute walk test in the coupled time. The third patient showed significant improvement in the six-minute walk test at the end of 12 months, while the other parameters did not change obviously. There were no severe adverse events during and post-HUC-MSC transplantation. During follow-up, no other immunosuppressive drugs were used. In conclusion, HUC-MSC therapy is a reasonable salvage treatment in HF. Future large-scale randomized clinical trials are likely to be designed to elucidate the efficacy of the HUC-MSC transplantation therapy on HF.

Abstract
Human umbilical cord-derived mesenchymal stem cells (hUCMSCs) represent a promising young-state stem cell source for cell-based therapy. hUCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery. To further clarify the paracrine effects of hUCMSCs on nerve regeneration, we performed human cytokine antibody array analysis, which revealed that hUCMSCs express 14 important neurotrophic factors. Enzyme-linked immunosorbent assay and immunohistochemistry showed that brain-derived neurotrophic factor, glial-derived neurotrophic factor, hepatocyte growth factor, neurotrophin-3, basic fibroblast growth factor, type I collagen, fibronectin and laminin were highly expressed. Treatment with hUCMSC-conditioned medium enhanced Schwann cell viability and proliferation, increased nerve growth factor and brain-derived neurotrophic factor expression in Schwann cells, and enhanced neurite growth from dorsal root ganglion explants. These findings suggest that paracrine action may be a key mechanism underlying the effects of hUCMSCs in peripheral nerve repair.

Abstract
Human umbilical cord-derived mesenchymal stem cells (HUCMSCs) are multipotent fetal stem cells that differentiate into various cell lineages. In recent years, they have gained attention for therapeutic applications but very little is known about their sensitivity to chemical agents such as widely used retinoic acid (RA). As a morphogen inducing differentiation of mesenchymal stem cells, RA has for a long time been known to be a potent teratogen promoting craniofacial and limb abnormality in vertebrate embryos. Here, using MTT assay and EB/AO staining as well as TUNEL assay we show that RA in a concentration-dependent manner induces apoptosis through upregulating Caspase expression and increasing Bax/Bcl2 ratio. Moreover, different biological parameters such as initial time seeding, cell density, passage number and duration of RA treatment play a major role in HUCMSCs cytotoxic response to this agent.

Abstract
The aim of this study was to investigate whether the chromosomes of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) change following in vitro culture for several generations. In the present study, umbilical cords from two healthy infants following cesarean delivery were collected aseptically and hUCMSCs were isolated by digestion with collagenase and trypsin, and then cultured in vitro. hUCMSCs with fibroblastic morphology were presented from the human umbilical cord tissue after 7 days of adherent culture. When cultured for 6 passages in vitro, the hUCMSCs maintained a stable spindle-shaped morphology. Cells reached the logarithmic growth phase after 3–4 days of culture. In addition, CD13, CD29, CD44, CD90 and CD105 were highly expressed in generations P3-P6. The expression of CD31, CD34, CD45 and HLA-DR was negative. Furthermore, karyotype analysis revealed a normal diploid karyotype with 46 chromosomes and no abnormal changes were found in chromosome structure. These findings suggest that when cultured for 6 passages in vitro, hUCMSCs maintain a stable immunophenotype and chromosome structure, which provides an experimental basis for the safety of hUCMSC cytotherapy.

Abstract
The use of human umbilical cord blood-derived mesenchymal stem cells for cell transplantation therapy holds great promise for repairing spinal cord injury. Here we report the first clinical trial transplantation of human umbilical cord (hUCB)-derived mesenchymal stem cells (MSCs) into the spinal cord of a dog suspected to have fibrocartilaginous embolic myelopathy (FCEM) and that experienced a loss of deep pain sensation. Locomotor functions improved following transplantation in a dog. Based on our findings, we suggest that transplantation of hUCB-derived MSCs will have beneficial therapeutic effects on FCEM patients lacking deep pain sensation.
