ABSTRACT:
A compartmentalized cell culture bag comprising a cell culture compartment defined by lower gas permeable film and an upper membrane selectively permeable to compounds of selected sizes. Culture medium resides between the upper membrane and the lower gas permeable film. A basal medium compartment is located above the upper membrane and allows basal medium to reside upon the upper membrane. Each compartment contains an access port. A gas film support below and in partial contact with the gas permeable film holds the gas permeable film in a substantially horizontal position so that suspension or adherent cells can distribute across the surface of the gas permeable film.
