Microfluidic devices have become popular in many life science fields, including stem cell research. As a microfabrication scientist, I have been proposing new assay systems as microphysiological systems (MPS). The assay systems that mimic the functions of human biological organs can be constructed on a chip to measure physiological functions that are difficult to measure on a culture dish. We have employed two approaches to create the interface between organ cells and vascular networks in MPS: a two-dimensional method in which organ cells and vascular endothelial cells are co-cultured on the top and bottom surfaces of a porous membrane coated with an extracellular matrix, such as Transwell (2D-MPS), and a three-dimensional method in which the spontaneous patterning ability of vascular endothelial cells is utilized (3D-MPS). A 2D-MPS, renal proximal tubule model, evaluates albumin and glucose reabsorption and nephrotoxicity, while the glomerular filtration barrier model evaluates inulin and albumin filtration mechanisms. I will also present recent results on the development of a co-culture system of organoids and vascular network as a 3D-MPS. Kidney and brain organoids were cultured on a vascular network to demonstrate their maturation and vascularization. The on-chip vascular network is expected to expand from basic researches including vascular biology to evaluate the correlation between shear stress and vascular morphogenesis.
