網頁First, cells undergoing apoptosis begin to shrink in size and lose physical connections with neighboring cells. Second, the chromatin, or the combination of DNA and protein within the cell nucleus, condenses and enzymes begin to fragment the chromatin within the cell. Third, the cell membrane bulges irregularly, or blebs. 網頁Induction of apoptosis by either extracellular or intracellular stimuli. (A) Extracellular activation. A killer lymphocyte carrying the Fas ligand binds and activates Fas proteins on the surface of the target cell. Adaptor proteins …
