Background/Aims: Diabetic nephropathy is one of the main causes of end- stage renal disease. The present study investigated the effect of mononuclear cell (MC) therapy in rats subjected to diabetic nephropathy. Methods: Male Wistar rats were divided into control (CTRL), diabetic (DM), CTRL+MC and DM+MC groups. Diabetes was induced by a single injection of streptozotocin (45 mg/kg, i.p.) and, 4 weeks later, 2x10(7) MCs were injected via the jugular vein. Results: The rats in the DM and DM+MC groups showed increased glycemia, glomerular filtration rate and glomerular tuff area versus control groups. The glomerular filtration rate and glomerular tuff area were normalized in the DM+MC group. No alterations were observed in the fractional excretion of electrolytes and proteinuria between the DM and DM+MC groups. TGF-beta 1 protein levels in the DM group were significantly increased versus control animals and normalized in the DM+MC group. An increase in ED1+/arginase I(+)macrophages and IL-10 renal expression was observed in the DM+MC group versus DM group. Conclusions: Bone marrow- derived MC therapy was able to prevent glomerular alterations and TGF-beta 1 protein overexpression and modulated glomerular arginase I+ macrophage infiltration in rats subjected to early diabetic nephropathy.
