During apoptosis (programmed cell death), the cell's cytoskeleton breaks up and causes the membrane to bulge outward. These bulges may separate from the cell, taking a portion of cytoplasm with them, to become known as apoptotic blebs. Phagocytic cells eventually consume these fragments and the components are recycled. Two types of blebs are recognized in apoptosis. Initially, small surface blebs are formed.
