Abstract: A method of forming an immunocompatible scaffold for a recipient. A decellularized tissue matrix is contacted in vitro with eukaryotic cells immunocompatible to the recipient to cover an exterior surface of the decellularized tissue matrix to form the immunocompatible scaffold. The decellularized tissue is formed from tissue xenogenic to the recipient. The decellularized tissue matrix may be contacted with alpha-galactosidase prior to recellularizing the decellularized tissue matrix. This process may be completed in a manner of days, rather than weeks. The immunocompatible scaffold may be fixed with a fixing agent such as glutaraldehyde, forming a shelf stable product.
