| Popis: | Objective To study the protective effects of hydroxysafflor yellow A (HSYA) against the oxidative damage caused by β-mercaptoethanol (BME) during neural differentiation of mesenchymal stem cells (MSCs) in vitro. Methods When the confluence reached 50%-60%, 4 th passage MSCs were divided into three groups to culture. G1: normal group which was cultured using basic medium (DMEM containing 10% FBS all the time); G2: unprotected group which was continuously cultured using basic medium for 24 h, and then cultured using pre-induction medium (DMEM containing 10% FBS and 1 mmol/L BME); G3: protected group which was firstly cultured using protective medium (DMEM containing 10% FBS and 160 mg/L HSYA) for 24 h, and then cultured using pre-induction medium for 24 h. After these treatments as above, cell viability, relative levels of SOD/GSH and apoptosis rate were respectively detected. The expression of Bcl and Bax was examined by Western blotting. After HSYA protection and BME pre-induction, neural induction was performed. The expression of NSE and MAP-2 was respectively analyzed on cellular and molecular levels. Results Compared with unprotected group, 160 mg/L HSYA could obviously improve cells viability, maintain high level of SOD and GSH in MSCs, reduce apoptosis rate and improve the ratio of Bcl/Bax. After protection with 160 mg/L HSYA, the survival time of neuron-like cells could be extended. Immunocytochemical staining showed that after 10 h of neural induction, the differentiated neuron-like cells in protected group were still in a good state, and the mRNA levels of NSE and MAP-2 were increased during the induction course checked. Conclusion HSYA could improve the resistance of cells to the oxidative damage caused by BME. |
