Abstract
Capillary rarefaction of the kidney is not only a result of CKD, but also a crucial link to promote the progression of CKD to renal interstitial fibrosis (RIF). Learning about the mechanism that may cause the renal capillary rarefaction is of great significance for improving vascular rarefaction and angiogenesis, as well as reducing the development of RIF. This review started with the renal cells around capillaries, such as endothelial cells, pericytes, and endothelial progenitor cells, then summarized their pathophysiological processes that may affect the normal vascular network structure of the kidney and their possible involvement in the repair mechanism of angiogenesis, so as to provide new treatment ideas for improving RIF and slowing down the CKD progression.
Key words:
Capillary rarefaction; Renal interstitial fibrosis; Endothelial cells; Pericytes; Endothelial progenitor cells
