COMPOSITION FOR REGENERATING GROWTH PLATE
The present invention provides a composition comprising fetal cartilage tissue-derived cells and a fetal cartilage tissue-derived extracellular matrix as active ingredients for regenerating a growth plate. The composition for regenerating a growth plate can inhibit bone bridge formation in a growth plate injury region without a scaffold and differentiate to a growth plate cartilage tissue to effectively fill and regenerate the injured region therewith, whereby the regenerated growth plate tissue can recover growth ability. In addition, the composition is compatible with and safe to biological tissues and is characterized by high reproducibility and homogeneity.
POLYOXAZOLINE MODIFICATIONS MITIGATE STRUCTURAL DEGENERATION OF BIOPROSTHETIC HEART VALVES
Compositions and methods for mitigating SVD mechanisms in BHV, including non-calcific SVD mechanisms, are provided.
Biological valve for venous insufficiency
A bioprosthetic valve for repairing a deep venous insufficiency in a subject includes a single leaflet from a xenogeneic heart valve attached at natural margins of attachment to a patch of valve wall tissue. The patch may extend axially above and below the leaflet and circumferentially on either side of the leaflet to provide a region for attaching the patch to a fenestration in a host vein. A bioprosthetic valve may be manufactured by excising a portion of a xenogeneic heart valve including a single leaflet and contiguous wall tissue, and may further comprise shaving off excess leaflet tissue from adjacent leaflets. A method of replacing a malfunctioning venous valve in a subject includes providing a bioprosthetic valve as described above and inserting it to the host vein.
In vitro method for creating a viable connective tissue and/or osseous tissue
The present invention relates to an in vitro method for creating a viable connective tissue and/or osseous tissue obtained by tribological solicitations of a biological culture. It further relates to a viable connective tissue and/or osseous tissue susceptible to be obtained by said method as well as to the use of said method or viable connective tissue and/or osseous tissue to prepare a biological implant.
Systems and methods for in-situ, bottom-up tissue generation
Embodiments of the present disclosure encompass systems and methods for in-situ/in vivo, bottom-up tissue generation for wound repair, repair of tissue defects, and the like. Embodiments of the systems of the present disclosure include modular scaffolds seeded with cells (modular tissue forming units (MTFUs)) for packing a tissue defect, such that these MTFUs are able to fill the wound bed with cells of one or more needed tissue types supported by the modular scaffolding particles.
Amnion tissue grafts and methods of preparing and using same
The invention provides method for preparing amnion tissue grafts, as well as the grafts themselves. In specific embodiments, the tissue graft comprises a single layer of dried amnion from an umbilical cord.
Compressed bone composition and methods of use thereof
The present disclosure relates to compressed bone compositions, bone implants, and variants thereof. The present disclosure also relates to methods of preparing compressed bone compositions, bone implants, and variants thereof. The present disclosure also relates to methods of using the bone compositions, bone implants and variants thereof.
Decellularized Nerve Graft and Method of Manufacturing the Same
The present invention relates to a decellularized nerve graft using allogeneic and heterologous nervous tissues and a method of manufacturing the same.
In the present invention, by using a low-concentration basic solution and a surfactant as a decellularization solution, cell and tissue toxicity caused by a solvent or surfactant remaining in the tissue may be minimized by minimizing the use of a basic solution and an anionic surfactant in the entire manufacturing process. In addition, a peristaltic pump may be used to maintain the tissue structure and effectively remove lipid and cells.
TISSUE FOR USE AS ALLOGENEIC OR XENOGENEIC TRANSPLANT AND METHOD FOR ITS PRODUCTION
Tissue for use as a transplant, which tissue is allogeneic or xenogeneic and respectively the tissue may express an MHC I molecule that is immunologically incompatible to the transplant recipient and/or may express an MHC II molecule immunologically incompatible to the transplant recipient. The tissue suitable for use as a transplant and the method for its production include a genetic alteration of the tissue that provides for immunologic compatibility of the tissue with a transplant recipient. In the tissue for use as a transplant, which tissue expresses allogeneic or xenogeneic MHC I and/or allogeneic or xenogeneic MHC II molecules, the expression of the allogeneic or xenogeneic MHC I is downregulated by at least 50% to up to 90%, preferably the expression of the allogeneic or xenogeneic MHC I is downregulated by at least 60%.
