Figure 7From: Increased MiR-221 expression in hepatocellular carcinoma tissues and its role in enhancing cell growth and inhibiting apoptosis in vitro Effect of miR-221 on cell growth and apoptosis of HCC HepB3 cells by Hoechst 33342/propidium iodide (PI) double fluorescent chromatin staining. HCC HepB3 cells were transfected with miR-221 inhibitor, mimic and different controls for 96 hrs and the cells were observed under microscope with Hoechst 33342/PI double fluorescent chromatin staining, × 200.Back to article page
