Fig. 8From: A promising antitumor activity of evodiamine incorporated in hydroxypropyl-β-cyclodextrin: pro-apoptotic activity in human hepatoma HepG2 cellsStudy of apoptosis with staining. A Morphology of HepG2 cells after Hoechst staining (200× magnifications). B Apoptotic cells induced by evodiamine or EVO/HP-β-CD complexes after TUNEL assay (100× magnification). C Apoptosis induced by 1 μM evodiamine or EVO/HP-β-CD complexes for 26 or 28 h, respectively, and detected by flow cytometry analysis after staining with Annexin V-FITC/PI. The percentages in the upper–right and lower–right corners are the portions of late-stage and early-stage apoptosis, respectivelyBack to article page
