Abstract
Background: Diabetic nephropathy (DN) is the most leading complication of renal disease. Mesenchymal stem cells (MSCs) therapy holds an excellent promise in the repair of injured tissues and organs. However, the precise effects of MSCs on renal cellular injury remain unclear. Objective: This work was designed to evaluate the possible reno-therapeutic role of MSCs in experimental streptozotocin (STZ)-induced DN in adult female albino rat model. Materials and Methods: Adult female albino rats were divided into three groups: Group I (control), Group II (diabetic group) and Group III (diabetic/MSCs treated group) where 1X10^6 iron oxide-labeled MSCs was infused once in rat tail vein. Blood glucose levels and biochemical parameters of the kidney function such as serum creatinine (Cr), blood urea nitrogen (BUN) and uric acid were estimated. After 8 weeks, kidney specimens were processed for light and electron microscopic studies. Morphometric measurements and statistical analyses were done. Results: STZ injection caused destructive glomerular, proximal (PCT) and distal (DCT) convoluted tubular changes within the renal tissue in the form of sloughed epithelium, vacuolated cytoplasm, pyknotic nuclei, congested blood vessels and mononuclear inflammatory cells infiltration that was supported by a significant increase in plasma concentrations of Cr, BUN and uric acid levels coupled to a significant elevation of Periodic-Acid-Schiff (PAS) reaction and increase in area percentage of collagen fibers. The ultrastructural assessment confirmed these distortions. In contrast, MSCs significantly corrected hyperglycemia and renal biochemical parameters with critical improvement in renal histopathological changes depicted previously. Conclusion: MSC-based therapies may play a substantial therapeutic role in DN.
