The downregulation of mitochondrial transcription factor A (TFAM) had no effect on the proliferation and apoptosis of HTR-8/SVneo cells A, the OD values at different time points between the negative control group and siTFAM group in HTR-8/SVneo cells. B, Representative images of HTR-8/SVneo cells labeled with Edu (red) were shown. Nucleus were stained with Hoechst (blue). Scale bar: 100 μm. C, The early and late apoptosis rates between the negative control group and siTFAM group in HTR-8/SVneo cells. *P less than .05; **P less than .01; ***P less than .001.
