Objectives: In this study, the effects of triiodothyronine (T3) on neurospheres isolated from SVZ of AD induced rats were examined. Methods: Eighteen male Wistar rats were classified into two groups: Sham (Sh) and STZ (Streptozotocin injected, 1.5 mg/kg in each lateral ventricle on days 1 and 3 after recovery). On day 21, the SVZ was extracted and neurospheres were cultured. T3 (50 nM) was added to the culture medium (STZ+T3 group) and then, the morphology and seladin-1 gene expression of neurospheres were evaluated. Results: The diameter and the number of neurospheres along with the gene expression of seladin-1 were significantly decreased in the STZ group compared to Sh group (P˂0.05) while the administration of T3 significantly (P˂0.05) increased all these parameters in the STZ group. Conclusion: STZ decreases the proliferation of stem cells extracted from SVZ and administration of T3 to the culture media improves the morphology and up-regulates the gene expression of seladin-1 of neurospheres.
