Histopathological examination of renal tissues in DN group (A, B, C and D) and DN + MSC (E, F and G): (A) Thickening of glomerular capillary walls &early nodularity (arrow) (HE ×1000, (B) Fibrin in Bowman’s space (arrow) &green sclerosis of glomerular tuft (MT ×1000), (C) Atrophic changes in cortical tubules with dilatation of lumen & casts (MT ×400), (D) Cast in collectingtubule (arrow) (MT ×400), (E) Peritubularstem cell collections (HE ×1000), (F) Increased mesangial cells& no thickening of capillary wall (PAS ×1000), (G) Increased cellularity of glomerular tuft & absence of sclerosis (MT ×1000).
