bleb assembly cell blebbing blebbing plasma membrane bleb assembly biological_process The assembly of a bleb, a cell extension caused by localized decoupling of the cytoskeleton from the plasma membrane and characterized by rapid formation, rounded shape, and scarcity of organelles within the protrusion. Plasma membrane blebbing occurs during apoptosis and other cellular processes, including cell locomotion, cell division, and as a result of physical or chemical stresses. membrane blebbing GO:0032060 plasma membrane blebbing plasma membrane bounded cell projection assembly
