(February 3, 2015) By
combining micro-imprinting and electro-spinning techniques, researchers at
Shanghai University’s Rapid Manufacturing Engineering Center have developed a
vascular graft composed of three layers for the first time. This tri-layered
composite has allowed researchers to utilize separate materials that
respectively possess mechanical strength and promote new cell growth - a
significant problem for existing vascular grafts that have only consisted of a
single or double layer.
