Figure 3

(a–h) TEM images of glomeruli. (Panels a and b) Arrows indicate substantial mesangial matrix accumulation in FvbROP Os/+ mice. (c and d). Arrows indicate glomerular podocyte foot processes, where podocyte foot process effacement was far greater in FvbROP Os/+ glomeruli. (e) Graph of the frequency of glomerular capillary involvement with podocyte foot process effacement in FvbROP +/+ and FvbROP Os/+ mice (n=3 mice for each group, n=6–8 glomerular capillaries counted/mouse). (f and g) Arrows indicate GBM in the affected mice. (h) Graph of GBM thickness (n=3 mice for each group, n=2–3 glomerular basement membrane loops measured per mouse). *P<0.001 vs control.
