Abstract (original English)

The present study is to clarify the effect of insulin-producing cells (IPCs) derived from adipose tissue mesenchymal stem cells (AT-MSCs) on diabetic-induced impairments as the abnormalities of testicular tissues, oxidative stress of testes, and defects of spermatogenesis. Diabetes was stimulated by streptozotocin (STZ) injection in male adult Sprague Dawley (SD) rats. Diabetes was confirmed by taking two highly consecutive fasting blood sugar readings; more than 300 mg/dl; within one week. Five million of IPCs derived from AT-MSCs; encased in TheraCyte capsule; were then directly transplanted (one implant for each rat) subcutaneously in diabetic rats. Implants were maintained for 3 months and the fasting blood sugar of the transplanted rats was observed every month. At the end of the experiment; serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were also estimated. The sperm parameters (count, motility, and abnormality) were recorded. In testicular tissue; GPX4, Bcl2, and Bax levels were evaluated, while oxidative stress and antioxidant enzymes activities were measured in the testes homogenate. Also, histopathological alterations were examined in the testes cross-section. In the results, it was found that IPCs treatment enhanced the serum testosterone, FSH, and LH levels. Diabetic-induced impairments in the sperm parameters were noticeably im
