Figure 6From: Dovitinib preferentially targets endothelial cells rather than cancer cells for the inhibition of hepatocellular carcinoma growth and metastasisDovitinib inhibited proliferation and enhanced apoptosis in HCC xenograft tumors. A) Ki-67 staining showed the proliferation of HCC cells was reduced in dovitinib-treated tumors. B) Cleaved PARP staining showed that apoptosis of HCC cells increased in dovitinib-treated tumors. Scale bars, 300 μm. Black star, P < 0.05; double black star, P < 0.01.Back to article page
