Activation of mesangial cells, glomerular sclerosis, and infiltration of macrophages in rats of the Thy-1 GN (a, c, e) and Thy-1 GN/anti-VEGF (b, d, f) groups at week 6. Glomerular damage in rats of the Thy-1 GN group at week 6 showed complete recovery to the original structure with no αSMA+-activated mesangial cells, minimal type IV collagen+sclerotic lesions, and minimal ED1+macrophage infiltration. In contrast, rats of the Thy-1 GN/anti-VEGF group at week 6 showed persistent segmental mesangial hypercellularity in glomeruli with αSMA+-activated mesangial cells, IV collagen+sclerotic lesions, and infiltration of ED1+macrophages.
