Kidney podocytes cannot naturally reproduce, but new paper by the Shankland Lab shows they can be replaced from an unexpected source.

To overcome this we developed a new tool to simultaneously fate map two distinct cell types in the kidney, and genetically test whether cells of renin lineage (CoRL) can transdifferentiate to a podocyte fate.
