ABSTRACT: 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.
Project description:Umbilical cord mesenchymal stromal cells (UC-MSCs) were treated with different concentration with hIL10 and the influences on the secretome analyzed
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.
Project description:Here, we use single cell transcriptomics to characterize a dynamic senescence process of in vitro expanded MSC products from adipose tissue (AD), bone marrow (BM), placenta membrane (PM) and umbilical cord (UC). We found that cultured MSCs underwent progressive cell aging. As compared to perinatal MSCs (derived from PM and UC), adult MSCs (derived from AD and BM) showed higher degree of senescence and impaired immunosuppressive function. Moreover, we identified the transcriptional network regulating the intra-population functional diversity, which provides us guidance to drive reprogramming of determined MSCs lineage with specific cellular functions for a particular therapeutic intent.

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. Two-condition experiment: control MSCs vs. PTH-stimulated MSCs. 1 control MSCs and 1 PTH-stimulated 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.

Project description:Performing global gene expression profiling for different types of (Mesenchymal stem cells) MSCs can provide important information that might help in understanding the biology and ontogeny of MSCs. Additionally, it might help in the understanding of the propensity and capacity of MSCs from a particular source to differentiate toward a particular lineage or adopt a certain fate. We used microarrays to detail the global gene expression profiling for different types of MSCs including bone marrow (BM), Adipose Tissue (AT), Umbilical cord (UC) and placenta(PL). The MSCs transcriptome profile was additionally compared to the transcriptome profile of dermal fibroblasts.
