Introduction: Review of microscopic studies on the fetal and neonatal kidney

Abstract

The developing mammalian kidney has been studied by light microscopic, electron microscopic, immunohistochemical, and autoradiographic techniques. The microscopic studies have been conducted on in vivo samples and in vitro samples. The cellular biology and molecular biology of the developmental steps have been clarified, but more investigations are needed. Information has also been collected concerning the influence of the environment on the microscopic development of the kidney.
