Project description:The aim of this study was to explore the gene expression and metabolites among multisite adipose-derived mesenchymal stem cells, and investigate the metabolic pathway of multisite adipose-derived mesenchymal stem cells using a multi-omics analysis. Subcutaneous adipose-derived mesenchymal stem cells (SASCs), perirenal adipose-derived mesenchymal stem cells (PASCs), and epididymal adipose-derived mesenchymal stem cells (EASCs) were isolated from Sprague Dawley rats. RNA and metabolites were extracted and sequenced using transcriptomics and metabolomics analyses, respectively. There were 720 differentially expressed genes (DEGs) in EASCs and 688 DEGs in PASCs compared with SASCs; there were 166 unique DEGs in EASCs, 134 unique DEGs in PASCs, and 554 common DEGs between EASCs and PASCs. Furthermore, there were 220 differential metabolites in EASCs, 249 differential metabolites in PASCs, 83 unique differential metabolites in EASCs, 112 unique differential metabolites in PASCs, and 137 common differential metabolites between EASCs and PASCs. The transcriptomics and metabolomics analyses identified four hub genes, one in EASCs and three in PASCs. There are functional differences among multisite adipose-derived mesenchymal stem cells that may be related to the hub genes Atac2, Rrm1, Rrm2, and Gla. The relevant signaling pathways are the Ras signaling pathway, HIF-1 signaling pathway, and the p53 signaling pathway.
Project description:We performed RNA sequencing on the sorted adipose stem cells (ASCs) from multiple white adipose tissue depots to analyze the differential expression and pathway enrichment analysis of adipose stem cells from different anatomical sites.
Project description:Proteomics for sorted low vs. high 20% of lamin A/C-expressing primary, human, adipose-derived stem cells compared to an unsorted population
Project description:we analyzed the expression level change of transcription factors in adipose derived stem cells during osteogenic differentiation and found a candidate target gene, Sox11. We defined that Sox11 suppresses osteogenic differentiation through overexpression and knock down of Sox11. total RNA obtained from adipose derived stem cells subjected to 1,3,6,10 or 14 days in osteogenic differentiation compared to undifferentiated control adipose derived stem cells.
