Abstract
A method and composition for enhancing the development of metanephric tissue upon transplantation into an allogenic or xenogenic host are disclosed. Metanephric tissue is removed from an embryonic donor and is contacted with a composition comprising one or more growth factors for metanephric development. The composition can be administered to the metanephric tissue in vitro prior to implantation of the donor tissue in the transplant recipient, or can be administered in vivo either during or subsequent to the transplantation procedure.
