WebFeb 26, 2024 · Blebs are cellular protrusions observed in migrating cells and in cells undergoing spreading, cytokinesis, and apoptosis. Here we investigate the flow of cytoplasm during bleb formation and the concurrent changes in cell volume using zebrafish primordial germ cells (PGCs) as an in vivo model. We show that bleb inflation occurs concomitantly … WebFeb 26, 2024 · Blebs are cellular protrusions observed in migrating cells and in cells undergoing spreading, cytokinesis, and apoptosis.

WebAug 20, 2024 · The experimental induction of blebs formation in non-invasive cells resulted in increased ability of these cells to invade into 3D matrices. ... For this reason, we examined the actin polymerisation state in the cytoplasmic fraction of colon cancer cells incubated with apelin. We focused on test based upon simple enzyme-inhibitor reaction. Bleb formation can be initiated in two ways: 1) through local rupture of the cortex or 2) through local detachment of the cortex from the plasma membrane. This generates a weak spot through which the cytoplasm flows, leading to the expansion of the bulge of membrane by increasing the surface … See more In cell biology, a bleb is a bulge of the plasma membrane of a cell, characterized by a spherical, "blister-like", bulky morphology. It is characterized by the decoupling of the cytoskeleton from the plasma membrane, … See more Apoptotic function 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 … See more • Charras GT, Coughlin M, Mitchison TJ, Mahadevan L (March 2008). "Life and times of a cellular bleb".
