any anomaly in the ability of podocyte foot processes (FPs) to retract or elongate and hence move quickly along the glomerular basement membrane (GBM); motility refers to the dynamic reorganization of the interdigitating FP structure in vivo , and to the cell migration of cultured podocytes in vitro that is seen as surrogate for the former; alterations in podocyte motility are considered to underlie foot process effacement, with changes in the leading edge of the cell and its interactions with the GBM; a rather stationary podocyte phenotype is believed to reflect a stable FP structure with intact slit diaphragms, whereas hypermotility is believed to promote the development of FP effacement and proteinuria
