Abstract
The invention relates to new flow-through cell culturing devices that include plates arranged in parallel and spaced to control the flow patterns and velocity of liquid medium flowing between the plates. The devices can also include gas-permeable, liquid impermeable membranes arranged between the plates. The devices can be used to culture cells, such as hepatocytes, at high levels of mass transport of nutrients, oxygen, and waste products, yet low levels of shear stress for extended periods of time and with high levels of cell function, e.g., in organ assist systems. The invention also includes new culturing plates for use in the devices, and methods of manufacturing these plates.
