In Vivo Behavior of Decellularized Vein Allograft1,2

After 8 weeks of arterial flow, decellularized vein allograft exhibits satisfactory strength, reduced antigenicity compared to fresh allograft, and supports cellular repopulation. These characteristics make it satisfactory for further tissue engineering; combined with luminal vascular cell seeding, it may prove useful as a small-diameter arterial bypass graft.
