    Abstract: Preserved tissue samples contain endogenous viable cells and retain or promote biological activity after being stored at temperatures above freezing for extended periods of time (e.g., from 14 days to 3 years). The preserved tissue samples are implanted in or on a subject and, after rehydration, they retain beneficial biological activity, promote beneficial biological activity, or both. The beneficial biological activity comprises promoting one or more of tissue healing, tissue growth, and tissue generation. Methods for preparing the preserved tissue samples include contacting a recovered tissue sample with one or more protectants, followed by lyopreservation. Suitable protectants include sugars, polyphenols, carotenoids, and combinations thereof. Preferred protectants include glucose, fructose, sucrose, trehalose, dextran, EGCG, and combinations thereof.
