Abstract
A cell culture device is disclosed where cells are confined in a liquid medium within a cell culture space. The cell culture space is delimited by at least three selectively permeable walls. One wall is formed by a sheet of tubes and is permeable to fresh nutrient medium, the second wall is formed of a layer of capillaries and is permeable to gaseous fluids, and the third wall acts as a micron sieve that allows the passage of spent nutrient medium, but retains the cells within the cell culture space. The cell culture device makes it possible to produce culture products, continuously and in bulk over a long period of time.
