Human umbilical cord blood-derived mesenchymal stem cells from 2 donors

ABSTRACT: screening of signature deterimes the individual variations in the therapeutic efficacy of human umbilical cord blood-derived mesenchymal stem cells There is paucity of information whether human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) from separate donors might have different effects on improving myocardial repair after myocardial infarction (MI). We screened cell surface genes by the comparing the cells that showed the best and worst efficacy, respectively, in repairing the infarcted myocardium of rats.

A Comparison of the Efficacy of Transplantation of Bone Marrow Derived Mesenchymal Stem Cells and Unrestricted Somatic Stem Cells on Outcome After Acute Myocardial Infarction

Project description:Unrestricted Somatic Stem Cells (USSC) are a cell population derived from umbilical cord blood. They have been shown to have greater plasticity than mesenchymal stem cells, and are being investigated as a therapeutic option for many disease states, including cardiovascular disease. In this study, we aimed to evaluate the efficacy of USSC on treating acute myocardial infarction (MI). We compared the effectiveness of USSC to the more widely studied bone marrow derived mesenchymal stem cell. Finally, we investigated whether pre-conditioning USSC prior to administration enhances their effectiveness. We determined effectiveness primarily using cardiac ultrasound, and supported these findings with histological analyses. We observed that pre-conditioned (guided) USSC had the most significant beneficial effect on cardiac function. (Pre-conditioned cells were grown in serum-free F12 media was supplemented with 50ng/ml Basic Fibroblast Growth Factor (bFGF), 20ng/ml Hepatocyte Growth Factor (HGF) and 20ng/ml Bone Morphogenetic Protein 2 (BMP2)). We performed microarray analysis of guided USSC and unmodified USSC to compare the gene expression profile of both cell populations, in order to evaluate whether any specific genes, or gene groups, were involved in mediating this beneficial effect.

Transcription profiling of human umbilical cord blood-derived mesenchymal stem cells in to investigate therapeutic effect in myocardial repair after infarction

Project description:Human UCB-MSCs showed donor-specific variation of therapeutic efficacy in improving LV systolic function, reducing infarct area, and preserving wall thickness after MI, even though there were no significant differences in MSC phenotypes. UCB-MSCs (M02) which showed better efficacy had better paracrine activity and unique gene expression profile than others. In DNA microarray, in contrast to M01, M02 showed unique gene expression profiles; up-regulated anti-apoptotic and down-regulated apoptotic gene expression. Experiment Overall Design: To evaluate the correlation of gene expression profile and therapeutic efficacy of UCB-MSCs, we selected two UCB-MSCs (M01 and M02) which showed worst and best efficacy, respectively, in improving post-infarction LV remodeling. Under 3 days differentiation condition as described previously, we compared four groups of UCB-MSCs (naÃ¯ve M01, differentiated M01, naÃ¯ve M02 and differentiated M02). And, we examined the transcriptome profiles of undifferentiated and differentiated cells using Affymetrix Human Genome U133 Plus 2.0 Array covering more than 47,000 human transcripts.

BET Protein Inhibitor JQ1 Induces Cell Cycle Arrest in Mesenchymal Stem Cells

Project description:Efficacy and safety of anticancer drugs are traditionally studied using cancer cell lines and animal models. Recently, a potential anticancer agent, JQ1, an inhibitor of bromodomain and extra terminal (BET) protein, has been shown to promote apoptosis of cancerous cells by arresting them in G1 phase of the cell cycle. However, the effect of JQ1 on normal cells is poorly understood. In this study, we investigated the safety of JQ1 by using human umbilical cord mesenchymal stem cells (MSCs) as an in vitro model system. Our results indicated that JQ1 induced cell cycle arrest in G1 phase of MSCs, but did not promote apoptosis. Microarray analysis of MSCs treated with JQ1 indicated that it down-regulated genes involved not only in cell cycle regulation but also DNA replication, mitosis, and cell division. Although many studies have suggested the potential of JQ1 as an anticancer agent, our findings suggest that it caused a deleterious effect on normal cells and may not be safe for anticancer therapy. Human umbilical cord derived MSCs were cultured in vitro and treated with either 100 nM or 500 nM JQ1 for 24 hrs. Gene expression of treated cells was compared to untreated cultured cells.

Gene Expression Profile of Human Umbilical Cord Mesenchymal Stem Cells (hUC-MSCs) Culutured in Chemical Defined Serum Free Medium

Project description:Human umbilical cord mesenchymal stem cells maintained multipotency and immunosuppressive ability when being cultured in chemical defined serum free medium, but gained different gene expression profile. We used microarrays to identify the transcriptional difference between human umbilical cord mesenchymal stem cells cultured in serum containing medium and chemical defined serum free medium. human umbilical cord mesenchymal stem cells were cultured in conventional serum containing medium and chemical defined serum free medium separately. Total RNA was extracted and hybridized on Affymetrix microarrays.
