Cytoplasmic blebs
Blebbing is one of the defined features of apoptosis. 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. Durin… WebThe cells became weakly adherent, developed conspicuous cytoplasmic blebs, and displayed mature megakaryocytic characteristics by light microscopy such as the development of azurophilic cytoplasmic granules and a mosaic pattern of oxyphilic patches, multiplication of nuclei, and enhancement of the PAS reaction and alpha-naphthyl acetate ...
