Abstract (original English)

Diabetes mellitus (DM) is a chronic illness manifested by uncontrolled glycemic levels. The present investigation was designed to explore the role of Geltrex, integrated with inducing factors, in driving the differentiation of rat adipose tissue-extracted mesenchymal stem cells (ADSCs) into efficient insulin-producing cells (IPCs) and to appraise the curative effect of the generated IPCs against type I DM rat model elicited by intraperitoneal injection of streptozotocin. ADSCs were harvested, characterized, and stimulated to differentiate into IPCs using a Geltrex matrix supplemented by a mixture of growth factors and other differentiation-inducing factors. The identity of the resultant IPCs was affirmed by measuring the expression levels of IPC-related genes and an insulin secretion assay. Then, the therapeutic efficacy of the well-characterized IPCs was assessed via implantation in a diabetic rat model. The Geltrex-based differentiation protocol successfully generated functional IPCs displaying upregulated levels of pancreatic endocrine genes. Moreover, the PKH-26 staining monitored the engraftment of IPCs into the pancreas of the treated rats. Additionally, IPC transplantation in diabetic rats elicited a significant enhancement in metabolic indices and motivated a significant overexpression of the pancreatic-specific genes. The therapeutic impact of the inoculated IPCs was f
