WJ-MSCs had a reparative repair effect on damaged ESCs. a Morphological changes of ESCs after treatment with mifepristone (60 μmol/L) for 48 h. b Absorbance of ESCs in different groups at 24 h, 48 h, and 72 h, as shown by CCK-8 assays. c, d The proportions of apoptotic cells in the three groups were evaluated by Annexin V/propidium iodide staining and flow cytometry. The proportion of apoptotic cells was higher in the non-cocultured group than the cocultured group and normal group. Data are expressed as mean ± standard deviation (SD). Scale bars = 10 μm.*P < 0.05; **P < 0.01
