Pericytes from Mesenchymal Stem Cells as a model for the blood-brain barrier.

ABSTRACT: Blood brain-barrier (BBB) in vitro models have been widely reported in studies of the BBB phenotype. However, established co-culture systems involve brain endothelial cells, astrocytes, neurons and pericytes, and therefore are often consuming and technically challenging. Here we use mesenchymal system cells (MSC) as a potential substitute for pericytes in a BBB model. Both MSC and pericyte markers in 2D culture environment were evaluated on different extracellular matrix compositions. Further experiments indicated that MSC contributed in a similar manner to pericytes in a co-cultured 3D model on increasing trans-endothelial electric resistance (TEER) and decreasing permeability against macromolecules.
