proteomics of small extracellular vesicles (sEVs) from adipose tissue derived mesenchymal stem cells (AD-MSCs) stimulated with or without IFN-γ

Project description:Mesenchymal stromal cells (MSCs) are used for ameliorating liver fibrosis and aiding liver regeneration after cirrhosis; Here, we analyzed the therapeutic potential of small extracellular vesicles (sEVs) derived from interferon-γ (IFN-γ) pre-conditioned MSCs (γ-sEVs). to anlyze the proteins in sEVs, proteomics of small extracellular vesicles (sEVs) from adipose tissue derived mesenchymal stem cells (AD-MSCs) stimulated with or without IFN-γ were performed.

Primary human bone marrow-derived mesenchymal stem cells (MSC) (Chip_9965581030)

Project description:Mesenchymal stem cells are known to be recruited to the tumor and contribute to a pro-inflammatory environment. The aim of this experiment was to identify potential direct targets of hsa-miR-1246 in human bone marrow derived mesenchymal stem cells in the context of inflammation. For this purpose, miR-1246 mimic or miRIDIAN microRNA Mimic Negative Control #2 both purchased from GE Healthcare Dharmacon Inc. were transiently transfected with LipofectamineÂ® 2000 (Invitrogen AG) at a final concentration of 30nM into primary MSCs. Transfection time was 48h according to manufacturerâs protocol. Transfections were performed in biological triplicates each.

Transcription profiling of Mesenchymal stem cells (MSC) maintained in FCS vs autologous serum analysed at passage 4

Project description:The purpose of this study was to determine whether the serum condition affected the gene expression in mesenchymal stem cells (MSCs). To that end, we compared gene expression in MSCs maintained in regular growth medium supplemented with fetal calf serum (FCS) with gene expression of MSCs cultured in regular growth medium supplemented with autologous serum (AS) for 3 different donors (i.e. donor2, donor3 and donor4). MSCs were cultured in FCS- or AS-supplemented medium and were analyzed at passage 4.

The role of mesenchymal stromal cells (MSC) in the development of acute myeloid leukemia

Project description:Acute myeloid leukemia (AML) is a clonal disorder of hematopoietic stem cells with a poor prognosis. It has been reported in many tumors that mesenchymal stem/ stromal cells (MSCs) support the growth of the malignant cells. In this study we analyzed the interaction between MSCs and AML cells in patients and in murine models of human AML. We found that MSCs from AML patients or leukemic mice supported the growth of AML cells in vitro better than MSCs originating from healthy mice or control persons. Interestingly, MSCs from AML patients who achieved complete remission didn’t support the growth of leukemia cells in vitro anymore. Due to the difficulty to obtain sufficient human MSCs, we developed a novel method to immortalize human MSCs. Immortalized MSC cells derived from AML patients also supported the growth of human AML cells better than MSC cells derived from a healthy donor. Among others, AMSCs increased entering of leukemic cells into cell cycle and at the same time protected the leukemia cells against exogenous toxic events such as chemotherapy or irradiation. In vivo, we observed an increase in the number of MSCs in the bone marrow of leukemic mice compared to healthy mice. Microarray data of AMSCs show upregulation of epithelial mesenchymal trasition genes. The polarization of MSCs towards an AML-supporting state depends on upregulated expression of the transcription factor Growth factor independence 1 (Gfi1). Loss of Gfi1 abrogated the tumor-supporting state of AML-associated MSCs. In summary, we report that MSCs support the growth of AML cells in a Gfi1-dependent manner.

Induced Mesenchymal stromal cells derived from iPS cells from aged individuals acquire a rejuvenation signature and a MSC-specific secretome

Project description:Human induced pluripotent stem cells (iPSCs) - derived mesenchymal stromal cells (iMSCs) are a potentially useful cell type for circumventing ageing-related shortfalls associated with primary mesenchymal or skeletal stromal cells (MSCs/SSCs). To date, the extent of the reflection of ageing-hallmarks in iMSCs differentiated from iPSCs derived from elderly donors remains unclear. In this study, we show that fetal (55 days post conception) femur-derived MSCs and MSCs isolated from aged (60 – 74 years) donors differ in their transcriptome and secretome profile. Yet, iMSCs irrespective of donor age and cell type acquired a rejuvenation gene signature, specifically, INHBE, DNMT3B, POU5F1P1, CDKN1C, GCNT2; also present in pluripotent stem cells but not observed in the parental MSCs. Furthermore, dendrograms generated from the transcriptomes of iMSCs derived from the human embryonic stem cell line H1, fetal and aged MSCs always clustered together with the parental fetal femur-derived MSCs. In addition, these were distinct from MSCs isolated from aged donors when comparing gene ontologies (GOs) related to ageing processes. Critically, in terms of regenerative medicine applications, iMSCs re-acquired a similar secretome (e.g. SERPINE1, SDF-1a, HGF, IL6, IL10, THBS1) to that of the parental fetal MSCs, thus re-enforcing their capabilities of imparting context dependent paracrine signaling.

Expression data from rat lung-resident mesenchymal stem cells and bone marrow-derived mesenchymal stem cells

Project description:Rat lung-resident mesenchymal stem cells (LR-MSCs) were isolated via bronchoalveolar lavage from fibroblast growth factor-10 (FGF-10) pretreated lungs. We characterized the similarity and diversity between LR-MSCs and bone marrow-derived mesenchymal stem cells (BM-MSCs) by transcriptional profiling of these two types of cells. In this dataset, we include the expression data obtained from LR-MSCs and BM-MSCs cultured under similar conditions at passage 5. These data are used to obtain genes that are differentially expressed by these two types of cells. 6 Total samples were analyzed. Both LR-MSCs and BM-MSCs are in three replicates.
