Engineered tissues, in which digestion and/or metabolism play main role, require the high number density of cells (~10
7-10
8cells/mL) to perform its as high physiological functions as in vivo. A method of production and designing such an engineered tissue in vitro is a basic technology in the tissue engineering field. This study proposed universal method of high-density cell culture, including designing of scaffold shape and medium flow rate. That is, a plate type scaffold with microstructures was designed to allow 10
7-10
8cells/mL HepG2 cells adhering on the scaffold. Optimum flow rate of medium, which supplies enough nutrition (glucose) and oxygen to support this high cell density, and the microstructure were calculated by biotransport analysis accounting the detachment and starvation of cells.
