Increased extrinsic apoptotic pathway activity in patients with hepatocellular carcinoma following transarterial embolization

Figure 3 Representative sections of patients from the study (A-D) and control (E-H) groups after hematoxylin staining (negative control, A and E), caspase-9 immunostaining (B and F), caspase-8 immunostaining (C and G) or cleaved caspase-3 immunostaining (D and H). Study: HCC post-TAE; Control: HCC. Higher immunoreactivity of caspase-8 and cleaved caspase-3 stain was observed in the study group than in the control group. Magnification, 400 ×. HCC: Hepatocellular carcinoma; TAE: Transarterial embolization.
