Task: Question Generation
Input (English): Mesenchymal stem cells (MSCs) under favorable conditions secrete a spectrum of cytokines that promote the survival of surrounding cells via paracrine mechanisms. We explored the impact of rat pancreatic extract (RPE) on cytokine secretion by MSCs and examined the influence of administration of conditioned media of MSCs treated with RPE on blood glucose levels in diabetic rats.', 'Cytokine levels (IGF-1, VEGF, bFGF) in conditioned media of MSCs treated with RPE were measured using enzyme-linked immunosorbent assays. We estimated blood glucose levels of STZ-induced diabetic rats following intraperitoneal injection of conditioned media from RPE-treated MSCs. We analyzed histopathology of pancreatic islets by insulin immunostaining and apoptosis through a TUNEL assay.', 'Levels of IGF-1, VEGF, and bFGF were significantly increased in RPE-CM compared with control media. Administration of conditioned media of RPE-treated MSCs significantly lowered the blood glucose levels of diabetic rats. After RPE treatment the insulin-positive area was increased and apoptosis of pancreatic beta cells decreased.
Output (English): Do mesenchymal stem cells treated with rat pancreatic extract secrete cytokines that improve the glycometabolism of diabetic rats?
