title: The number of nephrons in the mammalian kidney: environmental influences play a determining role.
abstract: Several lines of evidence, mostly derived from animal studies, indicate that changes in the fetal environment may affect the renal development. Fetal growth retardation is associated with a nephron deficit in both humans and animals. Changes in the supply of vitamin A to the fetus may be responsible for the variations in the number of nephrons in the human kidney. In utero exposure to hyperglycemia or drugs may also cause a nephron deficit.
