23 Jul Bioreactor For three-dimensional tissue perfusion culture
Abstract
A bioreactor suitable for perfusion culture of three-dimensional tissues and cells which includes a reaction chamber, a reservoir and a peristaltic pump connected in turn via infusion tubes, wherein the reaction chamber comprises a cover body and a box body including side walls, a bottom wall, a cut-off device, an overflow plate, a screen frame, a static pressure tank, a drainage chute and a drainage trench. The cut-off device is a floodgate or a weir dam. An overflow port which cooperates with the drainage trench is provided, and the screen frame is fixed to two side walls of the box body. The invention can solve the problem of cell death easily caused by non-uniformity of the flow field and uneven transfer of nutrient in the existing perfusion culture, is suitable for three-dimensional culture of tissues and cells, and can improve quality of tissue engineering products.
