Expression data from human Wharton's jelly stem cells

ABSTRACT: Human umbilical cord Wharton’s jelly stem cells (WHJSC) are gaining attention as a possible clinical source of mesenchymal stem cells for use in cell therapy and tissue engineering due to their high accessibility, expansion potential and plasticity. However, the cell viability changes that are associated to sequential cell passage of these cells are not known. In this analysis, we have identified the gene expression changes that are associated to cell passage in WHJSC. We used microarrays to detail the global programme of gene expression underlying cell passage on WHJSC.

Expression data from human Wharton's jelly stem cells

However, the cell viability changes that are associated to sequential cell passage of these cells are not known. In this analysis, we have identified the gene expression changes that are associated to cell passage in WHJSC. We used microarrays to detail the global programme of gene expression underlying cell passage on WHJSC. Total RNA was isolated from three different samples corresponding to cell cultures of three different individuals at each cell passage (P1 to P10) of WHJSC.

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 Wharton’s jelly and bone marrow (WJ-MSCs and BM-MSCs, respectively) and compared their transcriptional profiles.

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.

In this study, BM-MSCs and WJ-MSCs were isolated from 4 and 3 independent donors, respectively.

Comparison of human isogeneic Wharton’s Jelly MSCs and iPSC-derived MSCs responses to interferon-gamma (IFNG) stimulation

Project description:To explore differences between native MSCs (nMSCs) and iPSC-derived MSCs (iMSCs), we developed isogeneic lines from Wharton’s Jelly (WJ) from the umbilical cords of two donors (#12 and #13) under xeno-free conditions. Next, we reprogrammed them into iPSCs (iPSC12 and iPSC13) and subsequently differentiated them back into iMSCs (iMSC12 and iMSC13) using two different protocols, which we named ARG and TEX. As an additional control, we used human embryonic stem cell line KCL034 to differentiate the cells into eMSC following ARG and TEX protocols. We assessed IFNG-induced changes in all lines. Our data suggest that, following a careful selection and screening of donors, nMSCs from umbilical’s cord WJ can be easily reprogrammed into iPSCs providing an unlimited source of material for differentiation into iMSCs. However, the differentiation protocol should be chosen depending on their clinical use.

Comparison of single hWJSCs and hBMMSCs

Project description:The Wharton’s jelly of the human umbilical cord contains a population of mesenchymal stem cells that are unique and possess significant clinical utility. Known as human Wharton’s jelly stem cells (hWJSCs), they have broad differentiation potential, are proliferative and available in large numbers from discarded cords thus requiring minimum ex vivo expansion. They are safe and non-tumorigenic and maintain stemness properties for prolonged periods in culture. Besides their potential to produce tissues for cell based therapies, it has been demonstrated that they have anti-cancer and wound healing properties and provide cues for expansion of hematopoietic stem cells for treatment of hematopoietic malignancies. They are thus an attractive alternative source of MSCs of therapeutic value compared to bone marrow MSCs (hBMMSCs). We aimed to characterise the differences in gene expression profiles between these two stem cell types using single cell RNA sequencing to determine which pathways are involved in conferring hWJSCs with their unique properties.

Transcriptome analysis of human Wharton’s jelly stem cells

Project description:Human Wharton’s jelly stem cells (hWJSCs) are derived ethically in large amounts from the umbilical cord matrix. Besides their differentiation capabilities, WJSCs also display a notable lack of ability to form teratoma. hWJSCs have been shown to exert immunomodulatory effects and have recently been reported to kill or diminish cancer cell growth. These characteristics are important considerations for their use in cell therapy. In this transcriptome analysis, hWJSCs were profiled using Affymetrix DNA microarrays and compared to a panel of human stem cells and stromal cells. Although hWJSCs are multipotent, they expressed very low levels of the majority of stem cell markers, including POU5F1, NANOG, SOX2 and LIN28. BIRC5 has recently been shown to be required for teratoma formation in SCID mice. The lower levels of BIRC5 expression in hWJSCs compared to hESCs and the very low levels of stem cell markers might account for hWJSCs inability to form teratomas. IL12A which is known to be associated with the induction of apoptosis, was amongst the several cytokines identified to be significantly upregulated in hWJSCs. The ability of hWJSCs to compliment the host immune responses was further highlighted with the GO Biological Process analysis showing high association with immune system, chemotaxis and cell death. The ability to modulate immune responses confers hWJSCs an additional advantage in stem cell therapy and potentially allows hWJSCs as a form of treatment for cancer and immune disorders. In summary, the transcriptome profile of hWJSCs has provided indications on the genetic basis for their biological characteristics in immunomodulatory response, anti-cancer effects, and the lack of teratoma formation. This SuperSeries is composed of the SubSeries listed below.
