Project description:We developed a strategy to generate cardiac progenitor cells from human induced pluripotent stem cells using a novel small molecule.miRNA-sequencing results showed different miRNA expression profile among undifferentiated human induced pluripotent stem cells(hiPSCs), DMSO and ISX-9 treated hiPSCs.In comparsion with DMSO treated cells, ISX-9 upregulated several myogenic miRNAs and cardiac hypertrophy related-miRNAs including miR-335, miR-21, miR-30c,miRNA-181a and miR-214.
Project description:We developed a strategy to generate cardiac progenitor cells from human induced pluripotent stem cells using a novel small molecule. mRNA-sequencing results showed different gene expression profile among undifferentiated human induced pluripotent stem cells(hiPSCs), DMSO and ISX-9 treated hiPSCs.In comparsion with DMSO treated cells or undifferentiated hiPSCs, ISX-9 upregulated the genes related to WNT and cytoskeleton remodeling and TGF-β signaling, which are involved in heart development and cardiac differentiation. In addition, the genes related to cardiac differentiation signaling pathways were upregulated by ISX-9 including development of PIP3 signaling in cardiomyocyte myocytes, muscle contraction and NF-AT hypertrophy signaling.
