Davis Center for Regenerative Biology and Aging at the MDI Biological Laboratory in Bar Harbor, Maine, has identified the signaling mechanisms underlying the formation of podocytes, which are tiny, highly specialized cells in the glomerulus, the cluster of blood vessels in the kidney where waste is filtered. The discovery opens the door to the development of therapies to replace or regenerate these cells, which are vital to ridding the body of toxins.
