Podocytes are critical in the maintenance of a healthy glomerular filter, however they have been difficult to study in the intact kidney due to technical limitations. Here we report the development of serial multiphoton microscopy (MPM) of the same glomeruli over several days to visualize the motility of podocytes and parietal epithelial cells (PEC) in vivo. In Podocin-GFP mice podocytes formed sporadic multi-cellular clusters after unilateral ureteral ligation (UUO) and migrated into the parietal Bowman’s capsule. The tracking of single cells in Podocin-confetti mice featuring cell-specific expression of CFP, GFP, YFP, or RFP revealed the simultaneous migration of multiple podocytes. In PEPCK-GFP mice serial MPM found PEC-to-podocyte migration and nanotubule connections. Our data support the highly dynamic rather than static nature of the glomerular environment and cellular composition. Future application of this new approach promises to advance our understanding of the mechanisms of glomerular injury and regeneration.
