A The viability of 293T and HKC-8 cells was detected by CCK8 assays after administration of PBS, GC, H, GCH and Pm-GCH for 24, 48 and 72 h. B The viability of 293T/D cells was detected by CCK8 assays after administration of PBS, GC, H, GCH and Pm-GCH for 24 h. C Live/dead staining of 293T/D cells after various treatments (PBS, GC, H, GCH and Pm-GCH) for 24 h. D Semiquantitative ratio of cell death
