Early B-cell factor 1 is an essential transcription factor for postnatal glomerular maturation.

ABSTRACT: The coordination of multiple cytokines and transcription factors with their downstream signaling pathways has been shown to be integral to nephron maturation. Here we present a completely novel role for the helix-loop-helix transcription factor Early B-cell factor 1 (Ebf1), originally identified for B-cell maturation, for the proper maturation of glomerular cells from mesenchymal progenitors. The expression of Ebf1 was both spatially and temporally regulated within the developing cortex and glomeruli. Using Ebf1-null mice, we then identified biochemical, metabolic, and histological abnormalities in renal development that arose in the absence of this transcription factor. In the Ebf1 knockout mice, the developed kidneys show thinned cortices and reduced glomerular maturation. The glomeruli
