Abstract: Material processing apparatus, systems, methods, and products are described. An example of a material processing apparatus includes a holding member, a base, a tensioning member, an actuator, and a first inner member. The holding member defines a holding member passageway. The base is attached to the holding member. The tensioning member is partially disposed within the holding member passageway. The tensioning member defines a tensioning member passageway. The tensioning member is moveable relative to the holding member between a first position and a second position. The actuator is attached to the tensioning member and is moveable in a first direction and a second direction. Movement of the actuator results in movement of the tensioning member between its first position and second position. The first inner member is adapted to be disposed within the tensioning member passageway.

Abstract: Differential pressure material processing systems, apparatus, methods, and products are described. An example embodiment of a differential pressure material processing system includes a tank, a holding member, and a sheet of tissue disposed within the holding member. The holding member defines a first holding member chamber and a second holding member chamber. The first holding member chamber has a first pressure when a fluid is disposed within the first holding member chamber. The second holding member chamber has a second pressure when a fluid is disposed within the second holding member chamber. The second pressure is different than the first pressure.

Abstract: The present invention is related to compositions comprising decellularized cartilage tissue powder in the forms of paste, putty, hydrogel, and scaffolds, methods of making compositions, and methods of using these compositions for treating osteochondral defects and full- or partial-thickness cartilage defects.

Abstract: The present invention provides for a bioreactor system (3, 4) that is suited for one time use. The bioreactor system (3, 4) comprises a first bioreactor vessel (1), a second bioreactor vessel (20), a tissue retainer (35), and a cap (40). Advantageously, the bioreactor system (3, 4) of the present invention provides a sterile environment that is maintained over the course of cell seeding applications.
