Podocytes have a unique 3D structure of major and interdigitating foot processes
which is the prerequisite for renal blood filtration. Loss of podocytes leads to
chronic kidney disease ending in end stage renal disease. Until now, the question
if podocytes can be replaced by immigration of cells along the glomerular
basement membrane (GBM) is under debate. We recently showed that in contrast to
former theories, podocytes are stationary in the zebrafish pronephros and neither
migrate nor change their branching pattern of major processes over 23?hours.
However, it was still unclear whether podocytes are able to migrate during acute
injury. To investigate this, we applied the nitroreductase/metronidazole
zebrafish model of podocyte injury to in vivo two-photon microscopy. The
application of metronidazole led to retractions of major processes associated
with a reduced expression of podocyte-specific proteins and a formation of
subpodocyte pseudocyst. Electron microscopy showed that broad areas of the
capillaries became denuded. By 4D in vivo observation of single podocytes, we
could show that the remaining podocytes did not walk along GBM during 24?h. This
in vivo study reveals that podocytes are very stationary cells making
regenerative processes by podocyte walking along the GBM very unlikely.
