Abstract

Many experiments about endothelial cell seeding on artificial vessels were studied and conducted For this one or a combination of the extramatrix was used for the underlying matrix. But we used the whole ECM(extracellular matrix) that made excreated from flbroblasl. In thls study, we obtained human adult omental microvascular endothelium by collagenase digestion and used polyurthane sheets in order to make a new artificial vessel material. We cultured fibroblast on the polyurethane and gelatin - coated polyurethane. After confluent ingrowth we treated the polyure thane with triton in order to destroy the cytoskeleton and nucleus. We observed the preformed extra cellular matrix on the ployurethane and cultured the isolated microvascular endothelium. We also ok served the growth of microvascular endothelium on the polyurethane and gelatin. We conclude that the use of the whole ECM is promising fair as a new underying substrate for endothelial cell seeding on artificial vessels.
