In line with this observation, in human minimal change nephropathy biopsies from patients with a selective albuminuria, lymph vessel formation was not observed, whereas in unselective proteinuric glomerulopathies, such as IgA nephropathy and membranous glomerulopathy, interstitial lymph vessels were induced [21].We thus speculate that albumin-unrelated proteins induce VEGF-C in tubular cells. This evidence concerns the gene VEGFC and IgA glomerulonephritis.
