Abstract: The present invention provides constructs including a tubular biodegradable polyglycolic acid scaffold, wherein the scaffold may be coated with extracellular matrix proteins and substantially acellular. The constructs can be utilized as an arteriovenous graft, a coronary graft, a peripheral artery bypass conduit, or a urinary conduit. The present invention also provides methods of producing such constructs.

Abstract: Adipose tissue has proven to serve as an abundant, accessible, and rich source of endothelial or vascular endothelial cells suitable for tissue engineering. We describe a detailed method for the isolation and purification of endothelial cells using purified enzymes and antibody-based selection. The cells can be obtained from liposuction procedures and used in vascular grafts.
