Key Points

The aim is to investigate how a low-protein diet during gestation affects the development of the fetal kidney.
Examined the effects of a gestational low-protein diet on fetal kidney development
Analyzed nephron progenitor cell commitment and branching morphogenesis
Identified key developmental mechanisms responsible for nephron deficit
Low-protein diet resulted in reduced nephron endowment
Impaired commitment of nephron progenitor cells was observed
Alterations in branching morphogenesis were noted, contributing to nephron deficits

Abstract

This study demonstrates that gestational low-protein diet reduces nephron endowment by impairing nephron progenitor cell commitment, with concurrent alterations in branching morphogenesis. These findings position disrupted progenitor commitment as a central developmental mechanism underlying nephron deficit in this model.
