The present application is directed to a method of treating osteoarthritis, which includes obtaining a member of a transforming growth factor superfamily of proteins; obtaining a population of cultured mammalian cells that may contain vector encoding a gene, or a population of cultured connective tissue cells that do not contain any vector encoding a gene; and then transferring the protein and the connective tissue cells into an arthritic joint space of a mammalian host, such that the activity of the combination within the joint space results in regenerating connective tissue.

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.

A system for the therapeutic treatment of joints comprising a composite material comprising a biodegradable polymer matrix and a plurality of piezoelectric particles adapted to generate local electric charges in response to an external stimulation made by means of ultrasound, said plurality of piezoelectric particles being dispersed in the matrix. The composite material also comprises a plurality of stamina cells dispersed in the biodegradable polymer matrix and a plurality of carbon-based particles. The system also comprises a releasing device, arranged to deposit the composite material in a joint cavity at predetermined areas of the cartilage, and a stimulator device arranged to emit ultrasound at a predetermined frequency, a predetermined intensity and for a predetermined time of application, in such a way that, when the device is located near a joint wherein the composite material has been deposited, said ultrasound stimulate the plurality of piezoelectric particles.

The present application relates to a method of inducing differentiation of stem cells into chondrocytes using an oligopeptide, and a pharmaceutical composition for treating cartilage injury disease containing differentiated chondrocytes obtained by the method.

A method of making infused non-demineralized cartilage particles employs the following steps: cutting or shaving cartilage tissue into cartilage particles, washing the particles, and infusing the particles with a supernatant of biologic material or a polyampholyte cryoprotectant or a combination of both to create infused particles.

Methods and compositions for the biological repair of cartilage using a hybrid construct combining both an inert structure and living core are described. The inert structure is intended to act not only as a delivery system to feed and grow a living core component, but also as an inducer of cell differentiation. The inert structure comprises concentric internal and external and inflatable/expandable balloon-like bio-polymers. The living core comprises the cell-matrix construct comprised of HDFs, for example, seeded in a scaffold. The method comprises surgically removing a damaged cartilage from a patient and inserting the hybrid construct into the cavity generated after the foregoing surgical intervention. The balloons of the inert structure are successively inflated within the target area, such as a joint, for example. Also disclosed herein are methods for growing and differentiating human fibroblasts into chondrocyte-like cells via mechanical strain.

Described herein are biomaterials, systems, and methods for guiding regeneration of an epiphyseal growth plate or similar interfacial tissue structures. In one aspect, the disclosed technology can include a biologic material that can comprise one or more of a hydrogel carrier for growth factors and MSCs, chondrogenic and immunomodulatory cytokines, microparticles for prolonged and spatially controlled growth factor delivery; and/or porous scaffold providing mechanical support. The implanted material can be applied via various different modalities depending on the nature of the physeal injury. One modality is an injectable hydrogel and another modality is an implantable hydrogel infused scaffold.

A tissue or organ replacement includes a tissue-engineered construct that includes one or more bio ink compositions and a biocompatible support structure. The support structure includes one or more external supports, one or more internal supports, or combinations thereof of a biocompatible material. The composition has a three-dimensional (3D) shape, and the biocompatible material is present in an amount of about 1% to about 100% by weight of the biocompatible support structure.
