Figure 6C.Apoptosis measurements in HepG2 p53_/_ cells or huh cells after treatment with 0.02μM doxorubicin plus sFlt1 (concentrated conditioned medium) for 24h and for 48h. HepG2 p53-/-cells and huh7 cells exhibited increased apoptosis in response to combination treatment *p < 0.05, vs sFlt1 plus low-dose doxorubicin group.
