Blood brain barrier (BBB) is strong barrier specific to the brain vasculatures. BBB protects the brain from xenobiotics, while make it difficult to predict toxicokinetics/toxicodynamics, pharmacokinetics/pharmacodynamics, and efficiencies of new drugs in drug development. In this review, we will explain the physiological significance of BBB, the reason why the humanized BBB Micro Physiological System (MPS) is necessary, and the background technologies of BBB MPS. Because BBB MPS is the fusion of the engineering element technologies and the biological element technologies, we will explain the element technologies in both fields, respectively. We will also introduce the recent trends of BBB MPS to improve the human predictability: the shear stress in microfluidic models and the cellular architecture reproduction by three dimensional culture.
