In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, embodiments of the present disclosure, in one aspect, relate to TMJ implantation materials and implants (e.g., temporomandibular joint (TMJ) disc), methods of making TMJ implantation materials and implants, methods of forming a TMJ implantation material or an implant, and the like.

The disclosure relates to a chondrogenic cell sheet comprising at least two layers of confluent chondrogenically differentiated cells, wherein the cell sheet is prepared from mesenchymal stem cells (MSCs), and wherein the chondrogenically differentiated cells on the basal side of the cell sheet express adhesion molecules. The disclosure also relates to a method of preparing a chondrogenic cell sheet comprising: a) culturing MSCs on temperature responsive cultureware until confluent to form a cell sheet; b) detaching the cell sheet by temperature reduction and allowing the cell sheet to contract, forming a contracted cell sheet; c) contacting the contracted cell sheet with a culture surface; and d) treating the contracted cell sheet on the culture surface with chondrogenic medium and culturing to form a chondrogenic cell sheet. Methods of using the chondrogenic cell sheets to repair cartilage tissue or treat joint disease are also disclosed.

Apparatus and method for constructing a cartilage structure preferably has a first plate, and a blade mounted over the first plate. The blade preferably has (i) a predetermined shape, and (ii) a cutting edge protruding from the first plate and configured to cut a cartilage into the predetermined shape. A second plate preferably has a guide imprint adjacent a surface thereof, the guide imprint having a shape complimentary to the predetermined shape of the blade. A press preferably has (i) a first surface configured to mount the first plate, and (ii) a second surface configured to mount the second plate. Actuation structure is preferably configured to press together the press first and second surfaces to thereby cause the blade to cut the cartilage in the predetermined shape. The method utilizes similar structure to prepare at least two cartilages, which are joined together to form a three-dimensional cartilage structure.

A processing arrangement for tissue material removed from a patient and to be applied after processing, such as in particular an autologous cartilage or bone tissue, includes a collection container which has a collection receptacle for receiving the tissue material removed from a tissue removal device, a processing container which has a mixing receptacle for receiving the tissue material and a liquid to pasty medium, and a processing device for mixing of the tissue material and the medium. A connection device is provided, on which a first fastener for attaching the collection container and second fastener for attaching the processing container and one passage opening, which can be positioned between the collection receptacle and the mixing receptacle, are provided.

A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.

Disclosed herein is a composition comprising stimulated biological material derived from an interface compartment, wherein the composition is capable of augmenting the generation or healing of a native tissue when administered to a subject in need thereof.

A new preparation for regenerating tissues or healing wounds, which can be administered to a patient, which comprises serum and globin being insoluble at physiological pH, said preparation being obtained by adding said serum to said globin being insoluble at physiological pH.

The invention provides a method of making a biological disc graft. In one embodiment, the biological disc graft is useful for treating back or neck pain. In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.

A composition for the treatment of wounds includes demineralized bone fibers (DBF) derived from allogeneic or xenogenic cortical bone and/or polymeric fibers made from resorbable and/or non-resorbable polymer, and the composition may also include an oxygen-generating material and/or an oxygen carrier.

Methods of bioprinting a bio-ink construct on an internal tissue defect or a chondral defect during a minimally invasive surgery on an individual in need thereof are provided, comprising: visualizing the defect; positioning a bioprinter comprising a printhead within proximity of or in contact with the defect; and ejecting a bio-ink from the printhead onto the defect to form a bio-ink layer, thereby generating a bio-ink construct. Further provided are systems for bioprinting a bio-ink construct on an internal tissue defect during a minimally invasive surgery on an individual in need thereof, comprising a control system, an endoscope, and a bioprinter comprising a printhead.
