Cytoplasmic extensions of podocytes
WebElectron microscopy revealed cytoplasmic processes spanning the urinary space between the podocytes and PECs in developing and healthy postnatal kidneys, whereas the CNF and FSGS kidneys were characterized by numerous cellular bridges containing cells with strong expression of nestin and all analyzed proteins. WebPodocytes have a cell body with numerous primary, secondary and tertiary extensions, called foot processes. Adjacent foot processes are interconnected by slit diaphragms, whose main function is probably to act as mechanosensors and to form the final barrier to …

WebCytoplasmic buds could be seen at the base of some podocytes initially, when all podocytes were spherical. Parallel with the development of the first capillary loops, wider intercellular spaces were noted between elliptical-shaped podocytes. Podocytes then developed cytoplasmic processes and became flattened and star shaped.

WebJul 1, 2024 · Podocytes are characterized by interlocking cytoplasmic extensions, termed ‘foot processes’, enveloping the capillaries. Gaps between their shorter processes are … Podocytes are found lining the Bowman's capsules in the nephrons of the kidney. The foot processes known as pedicels that extend from the podocytes wrap themselves around the capillaries of the glomerulus to form the filtration slits. The pedicels increase the surface area of the cells enabling efficient ultrafiltration. Podocytes secrete and maintain the basement membrane.
WebMay 31, 2024 · The surface of the podocyte plasma membrane contains depressions 20–30 nm in size that are reminiscent of intramembrane particles; their nature is currently unknown. The podocyte filtration barrier appears as a ladder-like structure at the interface between adjacent foot processes with “slit diaphragm” structures overlaying the basal lamina [3].
WebJan 1, 2013 · Podocytes are dynamic cells with a prominent cytoskeleton that can effectively respond to changes in their extracellular environment.5 This cytoskeletal machinery is vital for a sustained kidney filtration, as defects in cytoskeleton-regulating proteins of podocyte foot processes result in proteinuria.5 Bundles of microtubules and … how to run benchmarks in blenderWebMar 15, 2002 · WT1 is expressed in the podocytes throughout life, but its function in this cell type is unknown.
