Expression data from human fetal cardiac MSCs

ABSTRACT: The instrinsic regenerative capacity of human fetal cardiac mesenchymal stromal cells (MSCs) has not been fully characterised. Here we demonstrate that we can expand cells with characteristics of cardiovascular progenitor cells from the MSC population of human fetal hearts with only minor fluctuations over time in culture (from day 15 to day 48). We used microarray to compare the gene-expression profile of cultured human fetal cardiac MSCs over time (from day 15 to day 48).

Expression data from human fetal cardiac MSCs

Project description:The instrinsic regenerative capacity of human fetal cardiac mesenchymal stromal cells (MSCs) has not been fully characterised. Here we demonstrate that we can expand cells with characteristics of cardiovascular progenitor cells from the MSC population of human fetal hearts with only minor fluctuations over time in culture (from day 15 to day 48). We used microarray to compare the gene-expression profile of cultured human fetal cardiac MSCs over time (from day 15 to day 48). MSCs from human fetal hearts were cultured on GelTrex in a defined medium stimulating the canonical Wnt/beta-catenin pathway. Samples from three different time points (day 15, 27 and 48) were compared on microarray.

Mesenchymal Stem Cells (MSCs): Control vs. PTH-stimulated

Project description:Transcriptional profiling of human MSCs comparing control MSCs with parathyroid hormone (PTH)-stimulated MSCs. PTH-stimulated MSCs were treated with 0.1 nM recombinant human PTH (N-terminal fragment, amino acids 1-34) for 48 hours. Human MSCs were isolated from a bone marrow sample obtained from a healthy adult volunteer.

Mesenchymal Stem Cells (MSCs) Alleviate Experimental Immune-mediated Liver Injury via Chitinase 3-like protein 1-mediated T cell suppression

Project description:RNA-seq for MSCs from human bone marrow (BM-MSCs), olfactory mucosa (OM-MSCs), and umbilical cord (UC-MSCs) (2 donors for each). RNA-sequencing for human naïve CD3+ T cells, CD3+ T cells activated with PHA (2.5 μg/mL) for 48 h， and CD3+ T cells co-cultured with human UC-MSCs in the presence of PHA for 48 h.

Transcription profiling of human MSCs during expansion

Project description:Human mesenchymal stem cells or multipotent stromal cells (MSCs) are of interest for clinical therapy, in part because of their capacity for proliferation and differentiation. However, results from clinical trials and in vitro models have been variable, possibly due to MSC heterogeneity and a lack of standardization between MSC in vitro expansion protocols. Here we defined changes in MSCs during expansion in vitro. In low density cultures, MSCs expand through distinct lag, exponential growth and stationary phases. We assayed cultures of passage 2 human MSCs from three donors at low density (50 cells/cm2) at about 5% confluence on Day 2 and after the cultures had expanded to about 70% confluence on Day 7. On Day 2 genes involved in cell division were up-regulated. On Day 7 genes for cell development were up-regulated. The variations between three donors were less than the variation within the expansion of MSCs from a single donor. The microarray data for selected genes were confirmed by real-time PCR, ELISA and FACScan. About 50% of cells at Day 2 were in S-phase compared to 10% at Day 7. The results demonstrated major differences in early and late stage cultures of MSCs that should be considered in using the cells in experiments and clinical applications. Experiment Overall Design: We assayed cultures of passage 2 human MSCs from three donors at low density (50 cells/cm2) at about 5% confluence on Day 2 and after the cultures had expanded to about 70% confluence on Day 7.

Comparison of bovine undifferentiated MSCs, chondrogenic MSCs and chondrocytes in 3D culture

Project description:Bovine chondrocyte-seeded and mesenchymal stem cell (MSC)-seeded agarose were cultured for 28 days in chemically defined media containing 10 ng/mL TGF-beta3. Chondrogenic differentiated MSCs were compared to chondrocytes at this timepoint and to undifferentiated MSCs harvested at day 0. Donor-matched sets of chondrocytes and MSCs were used, with three donors total.

Expression profiling of microRNAs during osteogenic differentiation of human MSCs

Project description:The goal of this study was to determine expression profiles of microRNAs (miRNAs) in whole cell extracts of human bone marrow-derived mesenchymal stem/stromal cells (MSCs) as well as in MSCs during osteogenic differentiation. MicroRNAs are epigenetic regulators that commonly function by targeting specific mRNAs resulting in suppression of protein expression and modulation of a number of cellular pathways. This experiment is part of a larger study analyzing the expression of mitochondria-associated miRNAs in MSCs during osteogenesis that we recently submitted to GEO (Series GSE134946). Here, the same three human MSC lines were used in this study, under the same osteogenic induction conditions, to generate expression profiles of miRNAs present in whole cell extracts. A standard in vitro osteogenesis assay system was used to differentiate MSCs toward the osteoblast lineage.Purified whole cell extracts were obtained from MSCs or from MSCs at specific time points of osteogenic induction. RNA was isolated from whole cell extracts and then biotin-labeled in preparation for microRNA array (Affymetrix miRNA array 4.0). Array data was analyzed to generate information on most abundantly-expressed miRNAs in non-induced MSCs as well as in MSCs at set time points (day 3, 7, or 14) of osteogenic induction. Information on significantly differentially-expressed miRNAs during osteogenesis (comparing day 0 with either day 3, 7 or 14) was also obtained.
