Researchers Unlock the Potential for Exploring Kidney Regeneration

ScienceDaily (Feb. 1, 2011) — Researchers  have identified a cell in zebrafish that can be transplanted from one fish to another to regenerate nephrons, providing the potential to improve kidney function.

It is estimated that up to 10 percent of the U.S. population may have some form of renal disease, with 450,000 patients with end stage renal disease (ESRD) requiring hemodialysis. Researchers at Brigham and Women's Hospital, Massachusetts General Hospital and the University of Pittsburgh have identified a cell in zebrafish that can be transplanted from one fish to another to regenerate nephrons, providing the potential to improve kidney function. These findings are published in the February 3 edition of Nature.

Currently, the five-year survival rate for patients on dialysis is 33 percent, worse than the survival rate for many forms of cancer. This epidemic of renal failure is projected to grow as obesity, poor nutrition and lack of exercise increase the incidence of diabetes and hypertension. There is also evidence that intra-uterine growth retardation and low birth weight/prematurity reduce the number of nephrons in each kidney thereby increasing the risk of  hypertension and renal failure when these premature infants become adults. The cost of treating end stage renal disease is currently 32 billion dollars annually and is likely to double in the next decade.
