Abstract:
Our previous studies have found that stem cells conditioned medium (CM) facilitated functional recovery after stroke in non-diabetics. However, whether bone marrow stromal cells conditioned medium (BMSCs-CM) treatment after stroke in type 2 diabetic (T2DM) rats improve functional outcomes remains unclear. T2DM rats were induced and subjected to stroke then treated with or without BMSCs-CM. Functional outcomes and blood-brain barrier (BBB) leakage were performed, the expression of Angiopoietin (Ang) 1 and tyrosine kinase (Tie) 2 were also assessed. Our results showed that BMSCs-CM treatment significantly improved functional outcomes, decreased BBB leakage and the expression of Ang1 and Tie2 were also changed after BMSCs-CM treatment in type 2 diabetes after stroke. In conclusion, enhanced expression of Ang1 and Tie2 in ischemic brain after BMSCs-CM treatment of stroke may contribute to the improved functional recovery after stroke in type 2 diabetic rats.
