Loss of Hnf1b in differentiated proximal tubule cells uncovers nephron segment plasticity
HNF1B is a transcription factor required for proximal tubule (PT) specification during kidney development, but whether it is also required to maintain PT identity after differentiation remains unknown. Using PT-specific genetic deletion in mice, we found that loss of Hnf1b in differentiated PT cells causes cyst formation and early postnatal lethality. PT-specific transcriptomic analysis revealed…
