MiR-146a-5p circuitry uncouples cell proliferation and migration, but not differentiation, in human mesenchymal stem cells

ABSTRACT: Administration of mesenchymal stem cells (MSCs) has the potential to ameliorate degenerative disorders and to repair damaged tissues. The homing of transplanted MSCs to injured sites is a critical property of engraftment. Our aim was to identify microRNAs involved in controlling MSC proliferation and migration. MSCs can be isolated from bone marrow and umbilical cord Wharton's jelly (BM-MSCs and WJ-MSCs, respectively), and WJ-MSCs show poorer motility yet have a better amplification rate compared to BM-MSCs.

miR-146a-5p expression effect on human mesenchymal stem cell

Project description:Analysis of human mesenchymal stem cells (MSC) from bone marrow and the Wharton's jelly of the umbilical cord after manupulating miR-146a-5p expression. miR-146a-5p is involved in controlling the proliferation and migration of MSCs. Results provide miR-146a-5p-regulating genes in MSCs. In this study, BM-MSCs transduced with miR-146a-5p expression vector or pCDH-CMV-MCS-EF1-copGFP vector only, as well as two WJ-MSCs transfected with short interfering RNAs targeting miR-146a or a GFP control.

Gene expression patterns of mesenchymal stem cells from bone marrow and Wharton's jelly of umbilical cord

Project description:Mesenchymal stem cells (MSCs) are promising tools for the treatment of diseases such as infarcted myocardia and strokes because of their ability to promote endogenous angiogenesis and neurogenesis via a variety of secreted factors. MSCs found in the Wharton's jelly of the human umbilical cord are easily obtained and are capable of transplantation without rejection. We isolated MSCs from WhartonM-bM-^@M-^Ys jelly and bone marrow (WJ-MSCs and BM-MSCs, respectively) and compared their transcriptional profiles. In this study, BM-MSCs and WJ-MSCs were isolated from 4 and 3 independent donors, respectively.

Whole transcript expression profiling of umbilical cord- and bone marrow-derived stem cells

Project description:Mesenchymal stromal cells (MSCs) are multipotent stem cells with potent immunosuppressive and trophic support functions. Although bone marrow is considered the golden standard to isolate classical MSCs (BM-MSC), MSC-like cells are currently also derived from other, more easily accessible extra-embryonic tissues such as the umbilical cord. In this study we compared the gene expression profile of human Wharton's jelly explant-derived MSC cultures with two adult MSC populations derived from bone marrow, namely BM-MSC and multipotent adult progenitor cells (MAPC). Here we demonstrate, by using genome wide gene expression analysis, that WJ-MSCs intrinsically have a differential gene expression profile compared to the adult MSCs. Gene ontology analysis revealed an increased expression of genes associated with cell-adhesion, proliferation, and immune system functioning. Furthermore, in comparison to adult MSC, stem cells from the Wharton’s jelly highly express genes involved in neurotrophic support (e.g. LIF, BDNF, NTF3). Such enhanced signatures make WJ-MSC an attractive candidate for cell-based therapy in neurodegenerative and immune-mediated CNS disorders such as multiple sclerosis or amyotrophic lateral sclerosis.

Quantitative proteomics analysis of different sources of hMSCs

Project description:Mesenchymal stem cells (MSCs) are an attractive therapeutic tool for tissue engineering and re-generative medicine due to their regenerative and trophic properties. The best-known and most widely used are bone marrow MSCs, but they are now being harvested and developed from a wide range of adult and perinatal tissues. MSCs from different sources are believed to have dif-ferent secretion potentials and production, which may influence their therapeutic effects. To prove it, we performed a quantitative proteomic analysis based on the TMT technique of MSCs from 3 different sources: wharton’s jelly (WJ), dental pulp (DP) and bone marrow (BM). Our analysis has focused on MSC biological properties of interest for tissue engineering. We identified a total of 611 human proteins differentially expressed. WJ-MSCs shown the greatest variation compared to the other sources. WJ produced more extra-cellular matrix (ECM) proteins and ECM-affiliated proteins and appeared to more able to modulate the inflammatory and immune response. BM-MSCs display enhanced differentiation and paracrine communication capabilities. DP-MSC appeared to promote exosome production. The results obtained confirm the existence of differences between WJ, DP and BM-MSC and the need to select the MSC origin according to the therapeutic objective sought.

Extracellular Vesicles Derived from Wharton’s Jelly Mesenchymal Stem Cells Inhibit the Tumor Environment via the miR-125b/HIF-1a Signaling Pathway

Project description:Purpose: small RNAseq analyses were conducted to identify the key miRNAs which involves in the regulation of tumor development in the Wharton's Jelly Mesehchymal Stem Cell-derived EV (WJ-EV) treated breast cancer cell (BCC) Methods: MDAMB231, a triple negative breast cancer cell line, were treated with WJ-EV at 0 and 24 hours, then the cell samples were harvested at 48 hours. The cells were cultured under a hypoxic condition (1%O2). Results: 1169 miRNAs were identified in original BCC and WJ-EV treated BCC (pBCC), respectively.

Gene expression profile of Wharton-jelly mesenchymal stem cells at 12th in vitro expansion cycle compared to Wharton-jelly mesenchymal stem cells at 4th in vitro expansion cycle

Project description:Mesenchymal stem cells (MSCs) are generally considered the main tool box for cell-based therapies and compared to embryonic stem cells (ESCs), MSCs exhibit many advantages. It has been shown that UC matrix (the Wharton’s Jelly surrounding umbilical vessels) contains a great number of mesenchymal cells. The abundant amount of Wharton’s Jelly (WJ) makes it an attractive source of MSCs for cell-based therapies. recently have been highlighted the changes in protein expression profiling during in vitro expansion of WJ-MSC, probably related to the gradual reduction of their staminal plasticity and to the biological cellular mechanism occurring in the cellular aging. The aim of the present work was to analyze the transcriptomic profile useful to the definition of WJ-MSC characteristics and therefore identify possible different new marker candidates. In these contest, changes in gene expression profiles occurring during WJ-MSC in vitro growth wile by analyzed in order to find possible modulation related to their long expansion and fast growth abilities. We analyzed the changes in total RNA expression at the 12th in vitro expansion cycle compared to the 4th in vitro expansion cycle.
