Plasticity of Renin Cells in the Kidney Vasculature

During development, renin cells are precursors for arteriolar smooth muscle, mesangial cells, and interstitial pericytes. Those seemingly differentiated descendants retain the memory to re-express renin when there is a threat to homeostasis. Understanding how such molecular memory is constructed and regulated would be crucial to comprehend cell identity which is, in turn, intimately linked to homeostasis.
