Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:To assess if human induced pluripotent stem cell-derived mesenchymal stem cells (hiPSC-MSCs) could be induce to acquire dermal papilla (DP) properties (especially hair inductive capacity), hiPSCs were initially programmed in serum-free MSC medium with FGF, TGFbeta and PDGF. Subsequently, hiMSCs were exposed to retinoic acid and activators of WNT, BMP and FGF signaling pathways. Global gene expression profiles were compared among primarily cultured human DP cells, hiPSC-MSCs before and after induction. Human dermal papillae were microdissected and cultured from different donors. Induction from hiPSCs to MSCs and subsequent sorting of CD271+CD90+ subpopulation and thier induction to DP was performed using WD39 hiPSC lines in two independent experimentations to generate hiPSC-MSC-1,hiPSC-MSC-2 ipDPSC-1 and ipDPSC-2.
