WebBackground: Among dysmorphic urinary erythrocytes (D cells), G1 cells or doughnut-shaped erythrocytes with one or more blebs are considered to be reliable markers for glomerular diseases. However, although there are many D cells with cytoplasmic color loss and without blebs in the urinary sediment, the significance of these cells is not clear. 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…
