This cell is flattened, highly fenestrated, and plays a vital role in the formation of glomerular ultrafiltrate. FMA:70970 Glomerular endothelial cells have 60-80 nm fenestrations typically lacking diaphragms in adults but present during embryonic development. Some studies found diaphragms in 2-6% of mature rat glomerular capillaries. Their presence may depend on fixation techniques, developmental stage, or dynamic cell changes. Additionally, these cells help maintain the structural integrity of glomerular capillaries through interactions with the basement membrane and podocytes.
