WebPericytes activate the expression of ADAMTS1, which cleaves the capillary basement membrane and capillary tubular network. Pericytes, in response to PDGF, TGF-β1, and Wnt ligands, will differentiate to myofibroblasts, detach themselves from endothelial cells, proliferate, spread, and migrate into the interstitium, producing pathologic ECM. WebAs we highlighted earlier, the reabsorption of filtrate into the peritubular capillaries is accounted for by two major processes; the transport of solutes through the nephron epithelial tissue (passive or active transport mechanisms) and the uptake of solutes into the peritubular capillaries. Web17. jan 2024 · Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen and occurs mainly by active transport and passive diffusion. It is the tubular secretion of H+ and NH 4 + from the blood into the tubular fluid that helps to keep blood pH at its normal level—this is also a respiratory process. committing to your goals and dreams
