Podocytes - the blood-filtering cells contribute to kidney function decline, say researchers. These cells are found to be the attractive targets for treatments against kidney failure.
Marcus Moeller, MD, Bart Smeets, PhD, Katja Berger (RWTH University of Aachen, in Germany), and their colleagues looked to see if they could coax podocytes to be generated from putative kidney progenitor cells- termed parietal cells- as a potential treatment strategy for kidney failure.
AdvertisementThrough experiments conducted in mice, the researchers found that podocytes cannot be renewed from parietal cells. In fact, after the loss of podocytes, parietal cells play a negative role by causing kidney scarring that contributes to progressive kidney function decline.
Moeller said this opens a very important new strategy to prevent loss of kidney function: by inhibiting the parietal cells from doing their destructive work.
The researchers did, however, detect an additional but limited reserve of podocytes that are present at birth and become mature and functional filter cells by adulthood.
The study will be published in Journal of the American Society of Nephrology.
