<i>In vitro</i> plasticity between ureteric epithelial and distal nephron identity and maturity is controlled by extracellular signals.

ABSTRACT: Several studies have described human pluripotent stem cell (hPSC)-derived ureteric epithelium, which in the embryo arises from the nephric duct and forms the collecting ducts of the kidney. However, hPSC-derived distal nephron epithelium can also adopt a ureteric phenotype, despite this not occurring during embryogenesis. In this study, RET^tdTomato and GATA3^mCherry reporter lines were used to further investigate this plasticity. Induction of anterior intermediate mesoderm resulted in the spontaneous formation of an epithelial plexus with a nephric duct-like identity. Subsequent addition of RSPO1 induced patterning of distalized nephrons, including distal convoluted tubule and thick ascending limb of loop of Henle but lacking proximal segments or glomeruli. This epithe
