    摘要: An implant for repair of a tissue defect comprises a plurality of physiologically compatible load-bearing sutures for securing under tension tissue adjacent to the defect to be repaired, the sutures for supporting a tissue reparative cell mass in the defect and a tissue reparative cell mass supported thereby. The sutures have a central portion encapsulated in a cell containing matrix which is contracted under a tensile load by the cells thereof and formed into a mat sheet during the contraction. Spring metal wires hold the sutures in tension during the contraction. The matrix is a collagen gel or other material which the cells contract, the cells comprising human mesenchymal stem cells. The mat sheet is then rolled into a spiral roll with the sutures extending from opposite roll ends to form the desired implant. Different embodiments are disclosed.

    摘要: A structurally rigid biodegradable foam scaffold useful for cell transplantation is provided. The foam can be loaded with nutrients and/or drugs that elute from the foam during transplant to promote growth of the cells. The foam, which features a continuous network of pores, is fabricated using a novel method involving phase separation and consequent expansion upon sublimation of a liquid solvent, preferably naphthalene.
