The present disclosure provides tissue supports and methods for preparing a cartilage composition for repairing cartilage defects, which is prepared by expanding and integrating small cartilage tissue pieces derived from donor or engineered tissue. The methods and supports described herein promote cell migration and integration of neighboring tissue pieces in culture to form the cartilage composition. Methods of cartilage repair using the cartilage composition are also described.
1. A method of making a cartilage tissue construct, the method comprising: placing a first surface of a first cartilage tissue piece and a first surface of a second cartilage tissue piece adjacent to an exposed surface of a solid or semi-solid support, wherein at least one of the first cartilage tis
1. A method of making a cartilage tissue construct, the method comprising: placing a first surface of a first cartilage tissue piece and a first surface of a second cartilage tissue piece adjacent to an exposed surface of a solid or semi-solid support, wherein at least one of the first cartilage tissue piece and the second cartilage tissue piece comprises a cartilage explant;culturing, in vitro, the first cartilage tissue piece and the second cartilage tissue piece on the exposed surface of the support, including reorienting at least one of the first cartilage tissue piece and the second cartilage tissue piece, relative to the support, to direct the expansion or shape of the reoriented cartilage tissue piece. 2. The method of claim 1, wherein reorienting includes placing a second surface of the reoriented cartilage tissue piece adjacent to the exposed surface of the support. 3. The method of claim 1, wherein opposing surfaces of the reoriented cartilage tissue piece are directed to expand such that the reoriented cartilage tissue piece is substantially symmetrical on the opposing surfaces. 4. The method of claim 1, wherein the first cartilage tissue piece is spaced 1 mm or less from the second cartilage tissue piece, and wherein culturing is under conditions and for a period of time such that the first cartilage tissue piece and the second cartilage tissue piece expand and integrate to form a larger cartilage tissue piece. 5. The method of claim 4, wherein the first cartilage tissue piece and the second cartilage tissue piece become integrated in about 42 days or less.
