Defining the dynamic chromatin landscape of mouse nephron progenitors.

ABSTRACT: Six2⁺ cap mesenchyme cells, also called nephron progenitor cells (NPC), are precursors of all epithelial cell types of the nephron, the filtering unit of the kidney. Current evidence indicates that perinatal 'old' NPC have a greater tendency to exit the progenitor niche and differentiate into nascent nephrons than their embryonic 'young' counterpart. Understanding the underpinnings of NPC development may offer insights to rejuvenate old NPC and expand the progenitor pool. Here, we compared the chromatin landscape of young and old NPC and found common features reflecting their shared lineage but also intrinsic differences in chromatin accessibility and enhancer landscape supporting the view that old NPC are epigenetically poised for differentiation.
