Abstract

Insulin secretion entirely depends on Ca2+ influx and sequestration into endoplasmic reticulum (ER) of β-cells, performed by Sarco-ER Ca2+-ATPase 2b (SERCA2b). In diabetes, SERCA2b is decreased in the β-cells leading to impaired intracellular Ca2+ homeostasis and insulin secretion. Adipose mesenchymal stem cells (AMSCs) play a potential role in transplantation in animal models. The present study aimed at investigating and comparing the therapeutic effect of non-transfected AMSCs and SERCA2b gene transfected AMSCs on the pancreas of induced diabetes type 1 in rat. 58 adult male albino rats were divided into: Donor group: 22 rats, 2 for isolation, propagation and characterization of AMSCs and SERCA2b transfected AMSCs, in addition 20 for isolated islet calcium level assessment. Group І (Control Group): 6 rats, Group II (Diabetic Group): 10 rats, 50 mg streptozotocin (STZ) were injected intraperitoneal (IP), Group III (AMSCs Group): 10 rats, 1×106 AMSCs were injected intravenous and Group IV (SERCA2b transfected AMSCs Group): 10 rats, 1×106SERCA2b transfected AMSCs were injected as in group III. Groups I, II, III and IV were sacrified 3 weeks following confirmation of diabetes. Serological, histological, morphometric studies and q...Continue Reading
