Cartilage-derived implants and methods of making and using same
Cartilage fibers and implants made therefrom are disclosed, with and without cartilage particles. Methods for making the cartilage fibers and the implants containing them are also disclosed. The implants may be pre-shaped, may be reshapable and, when implanted in a cartilage defect, the implants have good shape retention, little swelling, completely fill the cartilage defect and resist migration from the defect upon irrigation.
METHODS OF FORMING BONE INTERFACE SCAFFOLDS
Methods of forming a connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds (grafts) may be formed from in such a way as to provide both a mineralized and demineralized layer in which the entire graft is flexible, compressible and compliant.
Composition for cartilage regeneration and preparing thereof
The present invention provides a cartilage regenerating composition including a fetal cartilage tissue-derived cell and an extracellular matrix derived from a fetal cartilage tissue, and a preparing method thereof. According to the present invention, the cartilage-regenerating composition may produce a three-dimensional tissue of a size suitable for use as a cartilage without a scaffold, may be easily transplantable regardless of the size and shape of the cartilage defect at the site of administration since it can be administered in the form of a gel, but has high application and adhesion, may exhibit a high binding ability to the host tissue, and may have a phenotype of mature cartilage tissue, thereby exhibiting an excellent cartilage regeneration effect.
DIALDEHYDE STARCH CROSSLINKED SCAFFOLD COMPOSITIONS AND METHODS
Provided herein are compositions comprising collagen, dialdehyde starch, and at least one population of cells. Also, provided herein are methods of bioprinting and methods of producing cell-laden, three-dimensional scaffolds, comprising the compositions described herein.
DISRUPTED CARTILAGE PRODUCTS
A cryopreserved cartilage product is disclosed. The cryopreserved cartilage product can include a partially digested cryopreserved natural cartilage collagen matrix isolated from a subject. The collagen matrix can include viable cells embedded within the collagen matrix that are native to the collagen matrix and that were embedded in the collagen matrix when the collagen matrix was isolated from the subject, at least 70% of the embedded cells native to the collagen matrix can be viable in the cryopreserved cartilage product, and the partially digested collagen matrix can retain interaction between the collagen matrix and the native cells.
Disrupted cartilage products
This invention provides disrupted cartilage products, methods of manufacturing disrupted cartilage products, and methods of treating a subject comprising administering a cartilage product. The cartilage products are manufactured by a method comprising disrupting a collagen matrix, e.g. to produce a flexible cartilage product. Optionally, the cartilage products comprise viable chondrocytes, bioactive factors such as chondrogenic factors, and a collagen type II matrix. Optionally, the cartilage products are non-immunogenic.
Methods of manufacturing cartilage products
This invention provides porated cartilage products and methods of producing porated cartilage products. Optionally, the cartilage products are sized, porated, and digested to provide a flexible cartilage product. Optionally, the cartilage products comprise viable chondrocytes, bioactive factors such as chondrogenic factors, and a collagen type II matrix. Optionally, the cartilage products are non-immunogenic.
Osteochondral scaffold
There is described a multiphasic osteochondral scaffold for osteochondral defect repair, the scaffold comprising a bone phase and a cartilage phase, wherein the bone phase comprises a support matrix and the cartilage phase comprises a polymeric matrix, and the scaffold comprises a non-porous layer between the bone phase and the cartilage phase. Also described is a multiphasic osteochondral scaffold for osteochondral defect repair, the scaffold comprising a bone phase and a cartilage phase, wherein the bone phase comprises a support matrix and the cartilage phase comprises a polymeric matrix, and wherein the support matrix is tapered so that the dimensions of the support matrix are less at the lower end of the support matrix than at the upper end of the support matrix.
METHOD FOR CULTIVATION OF CARTILAGE AND SPHEROIDS THEREOF
The present invention relates to a method for propagating or enriching cartilage cells and providing spheroids thereof, wherein the spheroids are useful for an autologous chondrocyte implantation (ACI) product. Hence, the invention in particular relates to the production of spheroids from articular cartilage and use thereof.
MENISCUS TEAR REPAIR SLING DEVICE
A meniscus tear repair sling device has a collagen membrane having a first end portion and a second end portion. The first end portion is configured to pass under a tear in a meniscus and wrap over and above the tear and extend past the meniscus and overlay the second end portion thereby enveloping a portion of the meniscus with a tear and forming the sling device. The first end portion and the second end portion form exposed overlying tails extending external of a knee joint. The tails are configured to be affixed to a portion of a tibia. The tails when tensioned close the tear by providing a lateral strain on the torn meniscus when the tails are affixed to a tibia adjacent the knee joint.
