Project description:The bone marrow microenvironment is a complex mixture of cells that function in concert to regulate hematopoiesis. Cellular components include fixed nonhematopoietic stromal elements (MSC) as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells.

Project description:We have demonstrated that DICER1 (a key enzyme of miRNA biogenesis) was underexpressed in myelodysplastic syndrome MSC. We hypothesize that those MSC harbored a deregulated pattern of miRNA versus healthy donors MSC.

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. Bone marrow-derived MSC were expanded in DMEM (high glucose) medium containing 10% fetal bovine serum, 1% penicillin and streptomycin. At 80% confluency MSC were trypsinized and plated at 5x103 cells/cm2 in 6cm plates. Nearly confluent cells were serumstarved overnight and thereafter treated for 0, 3, 7, 14 and 21 days in low-serum medium (2% FBS) with the following treatments: (a) 10nM E2/1mM P4; (b) 0.5mM or 1mM 8-Br-cAMP (cAMP); (c) 50nM or 100nM BMP-2; (d) 0.5mM and 1mM 8-Br-cAMP + BMP-2; (d) 0.5mM and 1mM 8-BrcAMP + BMP-2 + E2/P4; (e) 50nM or 100nM human FSH, with vehicle controls at each time point. Each experiment was conducted in duplicate and repeated at least 3 times. Media were changed every third day. Endpoints were prolactin (PRL) and IGF binding protein-1 (IGFBP1) mRNA, assessed by quantitative real-time RT-PCR, and protein in conditioned media, assessed by ELISA (see below), after 3, 7, 14 and 21 days of incubation. Immunostaining for vimentin, cytokeratin 7, and Oct-4 was performed before and after MSC treatments to assess the stromal lineage of MSC and their differentiation status. MSC expressed vimentin and did not express cytokeratin or Oct-4, independent of culture conditions or duration of culture or treatment. The morphological appearance of MSC under different treatment conditions was photographed using a Leica CTR 6500 microscope. Microarray analysis was performed with MSC, n=3, at t=0 (untreated, uncultured control), 14day vehicle control, and 14day treated with 8-Br-cAMP. Only high quality samples (RIN=9.1-10) were used for microarray analysis. Hybridization was performed with Affymetrix Human Gene 1.0 ST arrays.

Project description:Mesenchymal stem/stromal cells (MSCs) are multipotent cells that can differentiate into a variety of cell types forming connective tissue and skeleton, and are essential participants in the development of all organs. However, MSC precursors remain largely unknown. In human embryonic stem cells (hESCs) directed to mesendodermal differentiation through coculture with OP9 stromal cells, we identified a population of mesodermal cells by surface expression of apelin receptor (APLNR1). APLNR+ cells were enriched with precursors generating compact spheroid colonies in semisolid suspension culture. Being formed by single cells, these colonies consisted of a uniform population of mesenchymal cells with a transcriptional profile representative of embryonic mesenchyme originating from lateral plate/extraembryonic mesoderm. Mesenchymal colony formation required serum-free medium and FGF2 as a colony-forming factor, could be significantly enhanced by PDGF-BB, but suppressed by VEGF. When transferred to the adherent cultures in serum-free medium with FGF2, individual colonies gave rise to multipotential mesenchymal cell lines with typical phenotype (CD146+CD105+CD73+CD31-CD43-CD45-), differentiation (chondro-, osteo-, and adipogenesis) and proliferation (>80 doublings) potentials. Consistent with lineage-restricted differentiation pattern, neither endothelial nor hematopoietic cells could be produced from adherent mesenchymal cultures, however endothelial cells could be derived from mesenchymal colonies in the early days of colony-forming culture suggesting that mesenchymal cells arose from cells with primary angiogenic potential (mesangioblasts). Together these studies identified mesangioblasts as the earliest clonogenic mesenchymal precursors at this stage of their specification from mesoderm. This set (11 samples) of expression data is sequential stages of MSC development from hESCs (H1), namely ALPNR+ mesodermal precursors isolated on day 2 and day 3 differentiation, mesangioblast (MB) cores (Day 2 H1-derived cores), hemangioblast (HB) cores (day 3 H1-derived cores), mesangioblast (MB) and hemangioblast (HB) colonies, and colony-derived MSC lines at passage 1 and 5.

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.
