| Research Abstract |
To study transmigration of mesenchymal stem cells (MSCs) across the blood-brain barrier (BBB), we developed an in vitro BBB system consisting of rat brain microvascular endothelial cells (BMECs). Time-lapse imaging using this system revealed that MSCs transmigrated across the BMEC monolayer through transiently formed intercellular gaps between the BMECs. In addition, we developed an in vitro imaging system for simultaneous analysis in real time between claudin-5, a tight junction protein, and intracellular calcium dynamics in BMECs during MSC transmigration.
