The present invention relates to a fibrocartilage preparation method and fibrocartilage prepared by the method.

A fetal-origin decellularized nucleus pulposus (NP) allogenic material to regenerate a host's Intervertebral Disc (IVD). The decellularized NP material, obtained from a vertebrate fetus and characterized by comprising high levels of collagen 12 and 14, is used in a pharmacological composition for the treatment of IVD degeneration. The advance is based on the increased ability of the fetal decellularized NP material to stimulate the host constituent cell's to increase the expression of collagen 2 and aggrecan, promoting intrinsic IVD regeneration. A related method includes preparing the pharmaceutical compositions of fetal decellularized material in the form of fragments/microparticles and hydrogel for an injectable mode of administration. The involved material, pharmaceutical compositions and methods may be advantageously used for the prevention and treatment of IVD degeneration and back pain in human and veterinary settings.

An intervertebral fusion device includes a structural ceramic body. The structural ceramic body has a bottom surface, a top surface, a peripheral surface connected between the bottom surface and the top surface, and at least one pore channel penetrating the bottom surface and the top surface. The inner surface of the pore channel is either a convex curved surface or a funnel-shaped surface. For the pore channel having the convex curved surface, the pore diameter of the pore channel gradually expands from the center of the pore channel to the top surface and the bottom surface. The pore diameter can also gradually expand from the bottom surface to the top surface. The peripheral surface of the structural ceramic body is wavy or zigzag.

This invention relates to a method for generating, repairing and/or maintaining connective tissue in a subject. In one embodiment, the invention relates to a method for generating, repairing and/or maintaining cartilage tissue in a subject. The present invention also relates to a method of treating and/or preventing a disease in a subject arising from degradation and inflammation of connective tissue.

This invention relates to a method for repair and reconstitution of invertebral discs in a subject which involves administration of STRO-1′ multipotent cells. The method of the invention is useful in the treatment of spinal conditions characterized by degeneration of the invertebral disc.

A method of treating soft tissue conditions. A harvesting device is provided. The harvesting device is operably connected to a tissue processing device using tubing. An aperture is formed in a bone. The bone has an interior. The harvesting device is inserted through the aperture in the bone and into the interior of the bone. The harvesting device is manipulated to dissociate connective tissue progenitor cells in the interior of the bone. Tissue is aspirated from the interior of the bone. The connective tissue progenitor cells are separated from the aspirated tissue. The separated connective tissue progenitor cells are injected in a region of a body that is experiencing a soft tissue condition to treat the soft tissue condition.

The present invention relates to a tissue-engineered intervertebral disc (IVD) comprising a nucleus pulposus structure comprising a first population of living cells and an annulus fibrosis structure surrounding and in contact with the nucleus pulposus structure, the annulus fibrosis structure comprising a second population of living cells and collagen.

The present invention relates to a method of providing a graft scaffold for cartilage repair, particularly in a human patient. The method of the invention comprising the steps of providing particles and/or fibres; providing an aqueous solution of a gelling polysaccharide; providing mammalian cells; mixing said particles and/or fibres, said aqueous solution of a gelling polysaccharide and said mammalian cells to obtain a printing mix; and depositing said printing mix in a three-dimensional form. The invention further relates to graft scaffolds and grafts obtained by the method of the invention.

A method for damaged viable disc regeneration has the steps of identifying the damaged viable disc and inserting a cannula via Kambin's Triangle to an edge of an outer annulus of the disc; introducing a trocar into the cannula and penetrating the trocar into a central region of nucleus pulposus; removing a tissue biopsy sample from the nucleus pulposus for pathology and removing additional degenerative tissue from the central region to create a void or space; withdrawing the trocar from the cannula and inserting a needle into the cannula to the void or space; and injecting a regenerative disc material through the needle into the void or space to repair the damaged disc.
