ABSTRACT:
A cell culture apparatus includes a housing, a bag and an inflatable bladder. The bag is disposed in the housing and has an interior surface defining a chamber for culturing cells. The bladder is disposed in the housing, external to the bag, and is sufficiently inflatable and expandable to exert pressure on the bag when the chamber is substantially free of fluid. The bladder may be inflated and expanded to reduce movement of the bag within the housing. Alternatively, or in addition, the bladder may be inflated and expanded to apply a mechanical stress on cells cultured within the chamber of the bag.
