  • Patent number: 9226494
    Abstract: A modular bioreactor is provided that includes an upper biochamber; a lower biochamber; and an intermediate biochamber that is positioned between the upper biochamber and the lower biochamber. Each biochamber of the bioreactor is in fluid communication with each other biochamber of the bioreactor and includes an interior wall, which defines a centrally-disposed cavity for each biochamber, and an inflow port and an outflow port that are in fluid communication with each centrally disposed cavity. Systems and methods for vascularizing a tissue construct are also provided.
