How is apoptosis regulated
WebMany cells undergo programmed cell death, or apoptosis, during fetal development. Apoptosis also may occur when a cell becomes damaged or deregulated, as is the case during tumour development and other pathological processes. Thus, when functioning properly, the body can induce apoptosis to rid itself of cancer cells. Not all cancer cells …
