iPSC-MSCs 对 CoCl2诱导的 PC12细胞损伤时线粒体功能的影响
Effects of iPSC-MSCs on mitochondria of PC12 cells injured by CoCl2
摘要
Abstract
[ ABSTRACT] AIM:To investigate the effects of induced pluripotent stem cells-derived mesenchymal stem cells ( iPSC-MSCs) on cobalt chloride ( CoCl2 )-induced injuries of PC12 cells and its possible mechanism.METHODS:PC12 cells were exposed to CoCl2 to set up a chemical-induced cellular injury model and were cocultured with iPSC-MSCs.The cell viability was tested by CCK-8 assay.The apoptosis was measured by flow cytometry using Annexin V/PI staining.The mitochondrial membrane potential (MMP) was analyzed by flow cytometry using JC-1 staining.Immunofluorescence was employed to observe mitochondrial transfer from iPSC-MSCs to PC12 cells.RESULTS: Apoptosis of PC12 cells was in-creased and MMP of PC12 cells was decreased after exposed to CoCl2 at concentration of 400μmol/L for 24 h.Coculture of PC12 cells with iPSC-MSCs reduced the apoptosis and recovered the MMP of the PC12 cells.Tunneling nanotubes were formed between iPSC-MSCs and PC12 cells, through which the iPSC-MSCs transferred the mitochondria to the PC12 cells. CONCLUSION:iPSC-MSCs protect PC12 cells from CoCl2-induced injuries, which may be associated with the mitochon-drial transfer from iPSC-MSCs to PC12 cells.关键词
