Abstract
Aspects of the disclosure relate methods and synthetic scaffolds for regenerating gastrointestinal tissue (e.g., esophageal tissue).
Claims26
A method, comprising the steps of:
- resecting a portion of a tubular organ in a subject, the resection step producing a resected organ portion, the resected organ portion remaining in the subject;
- implanting a synthetic scaffold at the site of resection, the synthetic scaffold including an outer polymeric surface and a cellularized sheath layer overlying at least a portion of the outer polymeric surface;
- maintaining the synthetic scaffold at the resection site for a period of time sufficient to achieve guided tissue growth along the synthetic scaffold, the guided tissue growth derived from and in contact with the tissue present in the resected organ portion remaining in the subject;
- and
- after achieving guided tissue growth, removing the synthetic scaffold from the implantation site, the removing step occurring in a manner such that the guided tissue growth remains in the contact with the resected portion of the tubular organ remaining in the subject.
2 more elements
A synthetic scaffold comprising:
- a body section, the body section having a first end and a second end opposed to the first end, the body section further having a least one portion configured as a tubular member, the body section comprising an outwardly oriented surface, the outwardly oriented surface having at least one region composed of spun polymeric fibers, the spun polymeric fibers having an average fiber diameter between 15 nm and 10 microns, at least a portion of the spun polymeric fibers interlinked to form pores having an average diameter less than 50 microns;
- and
- at least one sheath layer, the sheath layer composed of cellular material, the cellular material including at least one of mesenchymal cells, stem cells and pluripotent cells, the cellular material present in a defined layer the defined layer being between 1 and 100 cells thick.
