Abstract: A method for promoting healing of tissue by delivering a bioreactor into a subject is provided. The bioreactor is an enclosed housing with paracrine factor producing cells enclosed within the housing. The housing is impermeable to the paracrine factor producing cells, impermeable to immunological cells outside of the housing, and permeable to paracrine factors produced by the paracrine factor producing cells. The paracrine factors produced by the paracrine factor producing cells are released out of the housing to promote healing of the tissue.

Abstract: The present invention provides an implantable bioreactor comprising cells enclosed within an enclosure, said cells being capable of producing paracrine factors, wherein the enclosure is collapsible or expandable or both or neither, wherein the enclosure is semipermeable such that it provides containment of the cells preventing the egress of the cells while further providing a barrier that shields the cells from immunological attack, and wherein the enclosure is permeable to the entire secretome of the cell including exosomes, nucleic acids and proteins. The implantable bioreactor can have various configurations and can house internally a cell culture matrix than can include hydrogels, microbeads, and nanofiber matrices along with other active agents.

Abstract: An implantable bioreactor containing a barrier which is designed to allow the release of cell-derived biomolecules, but restricts the entry of immunologic and other cells, or the egress of the cells contained within the bioreactor. Two broad classes of implantable bioreactors are envisioned, encompassing devices for both systemic delivery of the bio-products and local delivery at the target tissue. Bioreactors of both classes can be implanted via surgery, through percutaneous techniques, or other techniques which effect implantation.
