BMSC-derived exosomes could inhibit the apoptosis of GCs. a Morphology of GCs. Scale bar: 100 μm b FSHR (red) expression in GCs. Nuclei were stained with DAPI (blue). Scale bar: 100 μm. c PKH67-labeled BMSC-derived exosomes (green) were incorporated into the cytoplasms of damaged GCs. Nuclei were stained with DAPI (blue). Scale bar: 20 μm. d The apoptosis rates of GCs as determined by flow cytometry. e Comparison of the percentages of apoptotic GCs in each group
