A polypeptide growth factor is associated with a substrate to promote population of the substrate with endothelial cells. In a preferred approach, the growth factor is associated with the substrate by crosslinking under suitably mild conditions such that the growth factor is active following the crosslinking process. Thus, a prosthesis is formed with growth factor crosslinked to the substrate.

Medical devices with associated growth factors

Crosslinked tissue is contacted with one or more toxicity reducing solutions to remove cytotoxicity associated with the crosslinking process. In particular, crosslinked tissue can be contacted with an inorganic sulfur-oxygen group to form chemical adducts of aldehydes and the inorganic sulfur-oxygen group. Preferably, the cytotoxicity reduced crosslinked tissue has no residual cytotoxicity. In preferred embodiments, a plurality of toxicity reducing agents are used to detoxify the tissue. Preferred toxicity reducing agents include, for example, inorganic sulfur-oxygen ions, such as bisulfate and thiosulfate, organic sulfates, amines, ammonia/ammonium, and surfactants.
