Research Abstract

The goal of this study is to achieve high-efficiency delivery of intravenously injected mesenchymal stem cells(MSCs) into the injured brain. We developed an in vitro culture system consisting of rat brain microvascular endothelial cells(BMECs) and bone marrow-derived MSCs. Live cell imaging using this system revealed that MSCs transmigrated across BMEC monolayers via a paracellular route. In addition, inhibition of MAP kinases affected transmigration of MSCs across BMEC monolayers.
