Mesenchymal stem cells (MSCs) are multipotential cells with capability to form coloniesin vitroand differentiate into distinctive end-stage cell types. Although MSCs secrete many cytokines, the efficacy can be improved through combination with neurotrophic factors (NTFs). Moreover, MSCs are excellent opportunities for local delivery of NTFs into injured tissues. The aim of this present study is to evaluate the effects of overexpressing NTFs on proliferation and differentiation of human umbilical cord-derived mesenchymal stem cells (HUMSCs). Overexpressing NTFs had no effect on cell proliferation. Overexpressing NT-3, BDNF, and NGF also had no significant effect on the differentiation of HUMSCs. Overexpressing NTFs all promoted the neurite outgrowth of embryonic chick E9 dorsal root ganglion (DRG). The gene expression profiles of the control and NT-3- and BDNF-modified HUMSCs were compared using RNA sequencing and biological processes and activities were revealed. This study provides novel information about the effects of overexpressing NTFs on HUMSCs and insight into the choice of optimal NTFs for combined cell and gene therapy.

Introduction: Human mesenchymal stem cells (MSCs) are the most popular stem cells applied in disease treatment. MSCs can be isolated and in vitro expanded from various sources such as bone marrow, peripheral blood, umbilical cord blood, umbilical cord tissue, and adipose tissue. According to Dominici et al. (2006), MSCs should express CD105, an essential marker used to confirm MSCs. However, some recent studies have show that MSCs contained a subpopulation that is negative for CD105. This study aimed to compare the immune modulation capacity of 2 populations of CD105 positive (CD105+) and negative (CD105-) MSCs derived from 2 sources: human adipose tissue (AT) and human umbilical cord (UC). Methods: MSCs were isolated from human adipose tissues (adipose tissue-derived mesenchymal stem cells – AT-MSCs) and human umbilical cord (umbilical cord-derived mesenchymal stem cells – UC-MSCs) according to previously published protocols. The two populations of CD105- and CD105+ MSCs were sorted based on the expression of CD105 from AT-MSCs and UC-MSCs. Four populations of CD105 (AT-MSCs, CD105+ AT-MSCs, CD105- UC-MSCs, and CD105+ UC-MSCs) were used to compare the phenotype as well as in vitro differentiation potential; then they were used to evaluate the immune modulation capacity by allogeneic T cell suppression and cytokine release. Results: The results showed that CD105- MSCs from AT and UC exhibited an immune modulation capacity that was much stronger than CD105+ MSCs from the same source of AT and UC. The strong immunomodulation of CD105- MSCs may relate to autocrine production of TGF-beta 1 by MSCs. Conclusion: The results suggested that CD105- MSCs are promising MSCs for application in regenerative medicine, especially for the treatment of diseases related to inflammation.

Recent studies indicated that Mesenchymal stem cell has become a potential objective for therapy. In this study, umbilical cord cells were isolated and analyzed the expression of mesenchymal stem cells specific markers then they were differentiated into hepatocyte-like cells by DMSO and Gene transfection. Umbilical cord mesenchymal stem cell (MSC) was isolated by explant culture in media DMEM/F12, complementing with growth factors EGF, FGF and IST. After that, they were exposured to DMSO with three concentrations: 0.01%, 0.1%, 1% and another group was transfection with HNF4α by Lipofectamin LX plus. The cells were analyzed at 1, 2, 3, and 4 weeks after treatment. The cells isolation was shown the positive with markers CD73, CD34, CD86, CD90, CD105, eras, Oct 1, GATA, and negative with markers HNF4α, Alb and G6P. In group 0,1% DMSO treatment, after 3 weeks the cells were positive with markers HNF4α but it was also negative with markers Alb and G6P. In the transfection group, the cell expresses HNF4α at three weeks after treatment. Although our results exposure that the umbilical cord mesenchymal stem cells expressed hepatic specific marker after DMSO induced and DNA treatment. So it will be necessary to optimize research conditional and investigate the hepatic functions of these cells in a longer in vitro culture.

Tissue Microenvironment

Human umbilical cord-derived mesenchymal stem cells (hUCMSCs) are considered to be an ideal cell source for cell therapy of many diseases. The aim of this study was to investigate the contribution of the microenvironment to the hepatic differentiation potential of hUCMSCsin vitroandin vivoand to explore their therapeutic use in acute liver injury in rats. We established a new model to simulate the liver tissue microenvironmentin vivousing liver homogenate supernatant (LHS)in vitro. This induced environment could drive hUCMSCs to differentiate into hepatocyte-like cells within 7 days. The differentiated cells expressed hepatocyte-specific markers and demonstrated hepatocellular functions. We also injected hUCMSCs into rats with CCl4-induced acute hepatic injury. The hUCMSCs were detected in the livers of recipient rats and expressed the human hepatocyte-specific markers, suggesting that hUCMSCs could differentiate into hepatocyte-like cellsin vivoin the liver tissue microenvironment. Levels of biochemistry markers improved significantly after transplantation of hUCMSCs compared with the nontransplantation group (P<0.05). In conclusion, this study demonstrated that the liver tissue microenvironment may contribute to the differentiation of hUCMSCs into hepatocytes bothin vitroandin vivo.

The purpose of this study is to evaluate the therapeutic effects of human umbilical cord-derived mesenchymal stem cells (hUC-MSC) activated by curcumin (CUR) on PC12 cells induced by 1-methyl-4-phenylpyridinium ion (MPP+), a cell model of Parkinson’s disease (PD). The supernatant of hUC-MSC and hUC-MSC activated by 5 µmol/L CUR (hUC-MSC-CUR) were collected in accordance with the same concentration. The cell proliferation and differentiation potential to dopaminergic neuronal cells and antioxidation were observed in PC12 cells after being treated with the above two supernatants and 5 µmol/L CUR. The results showed that the hUC-MSC-CUR could more obviously promote the proliferation and the expression of tyrosine hydroxylase (TH) and microtubule associated protein-2 (MAP2) and significantly decreased the expression of nitric oxide (NO) and inducible nitric oxide synthase (iNOS) in PC12 cells. Furtherly, cytokines detection gave a clue that the expression of IL-6, IL-10, and NGF was significantly higher in the group treated with the hUC-MSC-CUR compared to those of other two groups. Therefore, the hUC-MSC-CUR may be a potential strategy to promote the proliferation and differentiation of PD cell model, therefore providing new insights into a novel therapeutic approach in PD.
