CoCl2 (a chemical hypoxia-mimetic agent) was used to establish the chemical hypoxia-induced PC12 cell injuries model. Sodium hydrosulfide was used as a H2S donor. The viability of PC12 cells was measured by CCK-8 assay. The percentage of apoptotic cells was assessed by propidium iodide stain flow cytometry. The morphological change of apoptotic cells was tested by using the chromatin dye Hoechst 33258. The mitochondrial membrane potential was analyzed by rhodamine 123 staining and photofluorography. The level of reactive oxygen species in PC12 cells was measured by DCFH-DA staining and photofluorography.
