...the researchers were able to pinpoint a specific molecule responsible for renal cellular growth called the "WNT signal." Once activated in specific precursor cells in each kidney segment, the WNT signal results in robust renal cellular growth and generation of long branches of cells... We were amazed to find that renal growth does not depend on a single stem cell, but is rather compartmentalized," said Dr. Dekel. "Each part of the nephron is responsible for its own growth, each segment responsible for its own development..."

One way to upregulate WNT signalling is by supressing DKK1 with L-Throenate.

However care should be taken when upregulatig WNT due to cancer concerns:

"..."...while cancer biologist have mainly focused on the Wnt signaling pathway as the primary “early driver” of cancer. there is something else going on too.. Wnt drives β-catenin into the nucleus where it activates the transcription factor TCF to “turn on” the EMT. Watson believes an “even more important villain than Wnt signaling has been virtually staring us in the face for two decades”. That “villain” is interleukin 6 (IL-6). IL-6 is the master cytokine mediator of inflammation and immunity..."
