The Effect of Bone Marrow Mesenchymal Stem Cells (BMSCs) on Brain Injury Repair and Synapse Regeneration in Mice Under Different Conditions of Intrauterine Ischemia and Hypoxia Through Wnt Pathway

Abstract

Bone marrow mesenchymal stem cells (BMSCs) can be differentiated into a variety of cells and repair damaged cells. We explore whether BMSCs can repair brain damage and synapses regeneration in mice under intrauterine ischemia and hypoxia. Twenty-five pregnant mice were assigned into control group, 6% hypoxic injury group, 8% hypoxic injury group, 6% treatment group, 8% treatment group followed by analysis of the expression of MBP, MAG, CSPGs, IGF-1, NCAN, COLIV, SynD1G1, GFAP, GSK-3β, and β-actin by RT-PCR and Western blot. Our results showed that the expression of MBP, MAG, COL IV, SynD1G1, IGF-1 in the treatment group were significantly higher than those in hypoxic injury group with significant differences between the 8% treatment group and 6% treatment group (P < 0.05). In conclusion, BMSCs can repair brain damage and synapse regeneration in mice under different intrauterine ischemia and hypoxia conditions which might be through Wnt signaling pathway.
