Abstract

Chronic kidney disease is a global health problem with increasing morbidity and mortality. Therefore, this study was planned to test the protective effect of hematopoietic-stem-cell mobilization by granulocyte colony-stimulating factor (G-CSF) on Adriamycin (ADR)-induced chronic renal disease in rats. Thirty albino rats were equally divided into three groups: control, ADR group [rats received a single intravenous injection of ADR (5 mg/kg)], and G-CSF group [rats received ADR by the same route and the same dose as the previous group, and then G-CSF (70 μg/kg/d) 2 hours after ADR injection then daily for five consecutive days]. At the time of sacrifice (after 6 weeks), blood samples were taken to estimate the blood urea nitrogen and serum creatinine. Kidney sections were stained with hematoxylin and eosin, toluidine blue, Masson's trichrome, periodic acid-Schiff stains, and immunohistochemical staining against CD34 and caspase-3. The G-CSF group exhibited protection against renal injury manifested by reducing blood urea nitrogen and serum-creatinine levels, improving histological architecture, and increasing the proliferative capacity of renal tubules.
