The podocyte has long been viewed as a fascinating cell. It was first appreciated for its exquisite anatomy with primary, secondary and tertiary foot processes enveloping the glomerular capillary loops in a complex meshwork. Karnovsky described the highly specialized cell junctions at the glomerular basement membrane, the slit diaphragm, further highlighting its complex and highly specialized anatomy [1]. The podocyte was recognized as a key element of the capillary wall barrier to maintain normal permeability, and podocyte abnormalities, i.e. foot process effacement, were recognized early on to be key corollaries of proteinuria. The next era of interest in the podocyte began with
