摘要:
A biological material for the repair of connective tissue cells comprising: a) a cell preparation enriched in mesenchymal stem cells, b) three-dimensional extracellular matrix comprising a nyaluronic acid derivative. The use of said biological material, optionally combined with therapeutically acceptable excipients and/or diluents and optionally in association with therapeutically effective ingredients in the repair of connective tissue cells.
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:
Methods and apparatus for treating meniscal tissue damage are disclosed, including a biocompatible meniscal repair device comprising a stent. The tissue repair device is adapted to be placed in contact with a defect in the meniscus and can preferably provide a structure for supporting meniscal tissue and/or encouraging tissue growth through contact with vascularized portions of the meniscus or as a conduit for introduction of exogenous healing therapies.
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.
