Methods, Devices, and Systems for Bone Tissue Engineering Using a Bioreactor
An anatomically-shaped, human bone graft may be cultivated ex vivo using a bioreactor capable of perfusing large complex porous scaffolds. Scaffolds derived from image -based modeling of a target are seeded with human mesenchymal stem cells and cultivated. A bioreactor configured to house complex three-dimensional scaffold geometries provides controlled flow for perfusion of the cells. Dense uniform cellular growth can be attained throughout the entire scaffold as a result of the medium perfusion. In an embodiment, the bioreactor has a mold into which perfusion medium is pumped under pressure and multiple ports through which the medium exits the mold.
