This airlift reactor design was recently scaled down to 300,000L and evaluated using computational fluid dynamic models for the optimization of reactor geometry and internals for animal cell growth.
WebBioreactors can be used to apply fluid flow in vitro to scaffolds to improve mass transport of media and apply mechanical forces to cells. In this study, we developed and tested an autoclavable, modular perfusion bioreactor suitable for large scaffolds. WebVarious perfusion bioreactor systems have been designed to improve cell culture with three-dimensional porous scaffolds, and there is some evidence that fluid force improves the osteogenic commitment of the progenitors. However, because of the unique design concept and operational configuration of each study, the experimental setups of perfusion …
