H&E and immunohistochemical (IHC) characterization of tumor necrosis, apoptosis, and proliferation in VX2 tumor-bearing rabbits 7 days after embolization with NS, lipiodol, PVA, and PGEL. A Tumor tissue sections were stained with H&E (×100 magnification; the scale bar represents 100 μm), TUNEL (×200 magnification; the scale bar represents 50 μm), and Ki67 (×200 magnification; the scale bar represents 50 μm). B Tumor necrosis rate. C-D Quantitative analysis of TUNEL and Ki67. *P < 0.05, **P < 0.01, and ***P < 0.001
