Renal progenitor cells in the prevention and regression of age-related renal failure

Over 30% of older people suffer from chronic kidney disease. This may have to do with renal progenitor cells: with age, fewer may be produced or able to mature, leaving the kidney less able to repair itself. Dr. Anna Julie Peired’s research suggests that retinoic acid (RA), derived from vitamin A, counters these effects. If so, a vitamin A-rich diet or RA-based drugs could potentially delay or reverse age-related renal disease, reducing the need for costly therapies, like dialysis or kidney transplants.
