Vanadyl Sulfate Treatment Stimulates Proliferation and Regeneration of Beta Cells in Pancreatic Islets
Immunohistochemical staining of insulin in pancreatic Langerhans islet beta cells from nondiabetic rats. Note that insulin immunopositive cells are greater in (b) and more in (c). Control ND (a), ND treated with 5 mg/Kg of VOSO4 (b), and ND treated with 10 mg/Kg of VOSO4 (c). Six rats were used per group and 10 islets per rat were analyzed. Scale bar: 50 µm.
