Figure 3From: Emodin induces apoptosis of human cervical cancer hela cells via intrinsic mitochondrial and extrinsic death receptor pathwayCell apoptosis observed using Hoechst 33342 staining. HeLa cells were treated with Emodin (0, 20, 40, and 80 μM) for 48 h. Apoptotic cells exhibited Morphological changes in the nuclei typical of apoptosis. Photographs were taken under a fluorescence microscope (200×, original magnification). Arrows represent apoptotic cells.Back to article page
