Abstract

A stroke also called cerebrovascular accident (CVA) is the rapid loss of brain function due to disturbance in the blood supply to the brain It is one of the major lethal diseases in the modern era Mesenchymal stem cells (MSCs) are a heterogeneous population of cells that have fibroblast-like morphology form colonies in vitro and can differentiate into bone cartilage and fat cells In previous studies MSCs have been shown to activate endogenous restorative responses after brain injury possibly by the enhancement of angiogenesis neurogenesis and synaptogenesis Here a rat middle cerebral artery occlusion (MCAO) procedure was used to generate a stable ischemic-reperfusion model in the brain First we performed systemic pre-treatment with vascular endothelial growth factor (VEGF) to increase blood brain barrier (BBB) permeability which showed that more large particles were recruited at acute stage post-stroke Second we successfully increased the MSCs retention in the infarcted area by early VEGF pretreatment post-stroke Finally the therapeutic effect of MSCs could be facilitated and the infarct size post-stroke could be minimized These results suggest that enhancing the BBB permeability may promote cell therapy efficacy in cerebral infarction
