Project description:Mesenchymal stromal cells (MSC) are ideal candidates for cell therapies, due to their immune-regulatory and regenerative properties. We have previously reported that lung-derived MSC are tissue-resident cells with lung-specific properties compared to bone marrow-derived MSC. Assessing relevant molecular differences between lung-MSC and bone marrow-MSC is important, given that such differences may impact their behavior and potential therapeutic use. Here, we present an in-depth mass spectrometry (MS) based strategy to investigate the proteomes of lung-MSC and bone marrow-MSC. The MS-strategy relies on label free quantitative data-independent acquisition (DIA) analysis and targeted data analysis using a MSC specific spectral library. We identified several significantly differentially expressed proteins between lung-MSC and bone marrow-MSC within the cell layer (352 proteins) and in the conditioned medium (49 proteins). Bioinformatics analysis revealed differences in regulation of cell proliferation, which was functionally confirmed by decreasing proliferation rate through Cytochrome P450 stimulation. Our study reveals important tissue-specific differences within proteome and matrisome profiles between lung- and bone marrow-derived MSC that may influence their behavior and affect the clinical outcome when used for cell-therapy.

Project description:In the current study, we hypothesized that if bone-marrow derived MSC contribute to endometrial regeneration and are progenitors to hESF, their treatment with agents known to regulate hESF differentiation could promote their differentiation down the stromal fibroblast lineage. To this end, we treated bone marrow-derived MSC with estradiol (E2) and progesterone (P4), BMP2, and activators of the PKA pathway and investigated specific markers of hESF differentiation (decidualization). Furthermore, we investigated the transcriptome of these cells in response to cAMP and compared this to the transcriptome of hESF decidualized in response to activation of the PKA pathway. The data support that MSC can be differentiated down the hESF pathway, as evidenced by changes in cell shape and common expression of decidual markers and other genes important in hESF differentiation and function.

Project description:We found that bone marrow-derived mesenchymal stromal cells (MSC) establish nanotubular connections with T cells in a Talin 2 (TLN2)-dependent manner and leveraged these intercellular highways to supply new mitochondria to CD8+ T cells. In this experiment we analyzed the transcriptional profile of T cells co-cultured with MSC containing MSC derived Mitochondria (MitoPositive), T cells co-cultured with MSC not containing MSC derived Mitochondria and control T cells.

Project description:In this study, we characterize the fusion protein produced by the EPC1-PHF1 translocation in Low Grade Endometrial Stromal Sarcoma (LG-ESS) and Ossifying FibroMyxoid Tumors (OFMT). We express the fusion protein and necessary controls in K562 Cells. The fusion protein assembles a mega-complex harboring both NuA4/TIP60 and PRC2 subunits and enzymatic activities and leads to mislocalization of chromatin marks in the genome, linked to aberrant gene expression.

Project description:The aim of the study was to get insights into transcriptional alterations in bone marrow mesenchymal stromal cells derived from acute myeloid leukemia patients We compared the global gene expression profile from AML BM-MSC (n=19) to healthy donor (HD) controls (HD BM-MSC n=4) AML BM-MSC and HD BM-MSC were isolated from bone marrow aspirates (see below) and hybridized on an Affymetrix HG-U133 Plus 2.0 GeneChip

Project description:We isolated non-hematopoietic cells from fibrotic and non-fibrotic human bone marrow and perfomed scRNAseq on them. We identified 3 different stromal populations and 2 populations of hematopoietic progenitors. Our analysis revealed mesenchymal stromal cells (MSC) as pro-fibrotic cells. MSCs were functionally reprogrammed with loss of their progenitor status and acquisition of a pro-fibrotic phenotype in the fibrotic bone marrow. Additionally, stromal cells exhibited an upregulation of pro-inflammatory mediators like S100A8/A9.

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.
