You're asking a lot from river there Dave... Perhaps this super-secret link to the answer will help: https://www.google.com/search?q=How often kidney cells recycle themselves
Thank you Dave & Randwolf for stimulation with Google. I found It was thought that kidney cells didn’t reproduce much once the organ was fully formed, but new research shows that the kidneys are regenerating and repairing themselves throughout life. https://med.stanford.edu/news/all-news/2014/06/adult-kidneys-constantly-grow.html JUN 192014 ontrary to long-held beliefs, a new study shows that kidneys have the capacity to regenerate themselves. Shutterstock Researchers at the Stanford Institute for Stem Cell Biology and Regenerative Medicine and theSackler School of Medicine in Israel have shown how the kidneys constantly grow and have surprising ability to regenerate themselves, overturning decades of accepted wisdom that such regeneration didn’t happen. It also opens a path toward new ways of repairing and even growing kidneys. “These are basic findings that have direct implications for kidney disease and kidney regeneration,” said Yuval Rinkevich, PhD, the lead author of the paper and a postdoctoral scholar at the institute. The findings were published online May 15 in Cell Reports. It has long been thought that kidney cells didn’t reproduce much once the organ was fully formed. The new research shows that the kidneys are regenerating and repairing themselves throughout life.
