In vitro blood-brain barrier reconstruction model (BBB Kit) and their application to the functional analysis

The blood-brain barrier (BBB), a member of the neurovascular unit (NVU), functions in communication between brain capillary endothelial cells and other neighboring cells such as astrocytes and pericytes. Many drugs that are currently under development are intended to act centrally, but they do not cross the BBB. Furthermore, the crosstalk between the BBB and related cells contributing to the NVU remains to be elucidated. Based on our breakthrough in using rat primary brain capillary endothelial cells, pericytes and astrocytes to create a triple co-culture BBB model (BBB Kit), an in vitro models for screening the BBB penetration of drug candidates and research on BBB pathophysiology, we succeeded in modeling the monkey BBB with primary monkey brain capillary endothelial cells, rat pericytes and rat astrocytes. In addition, we constructed a porcine BBB model consisting of porcine brain capillary endothelial cells, rat pericytes, and rat astrocytes
