Methods and devices for cell or tissue culture are provided. One aspect provides a bioreactor having a gas permeable, closed-loop chamber for cell or tissue culture, and an oscillating means for moving the gas permeable, closed-loop chamber bidirectionally along an axis horizontal to an axis normal to the closed-loop chamber to force convection of cells and fluid in the gas permeable, closed-loop chamber. The bioreactor optionally includes a tissue engineering scaffold, an inlet means, an outlet means, and integrated sensors. Another aspect provides a bioreactor having a plurality of gas permeable, closed-loop chambers for cell or tissue culture. Methods of culturing cells and producing tissue constructs are also provided.
