ABSTRACT
The blood-brain barrier (BBB) is a major hurdle for treatment of brain diseases. To overcome this, precise and reproducible BBB model is one of the key factors for successful evaluation of BBB-penetrating efficacy of developmental drugs. Thus, in vitro BBB model recapitulating the physiological structure of the BBB is a valuable tool for drug discovery and development for brain diseases. Here, we develop a simplified 3D co-culture-based BBB model using immortalized human brain endothelial cells and immortalized human astrocytes mixed with Matrigel allowing model preparation within 30 min. We directly compare our 3D BBB model to a 2D BBB model comprised solely of immortalized brain endothelial cells, to demonstrate that our 3D BBB model blocks penetration of Dextran molecules with various molecular weights, remain durable and impermeable even in a BBB-degrading condition, and rapidly form tight junctions while the 2D BBB model do not. In conclusion, this establishes our simplified 3D BBB model as a valuable tool for high throughput screening of drug candidates for brain diseases.
