, PVA based implants with promising properties of in situ endothelialization, showed a very good patency rate in rats (75% at one month, 1% ratio, p.50
, at 2 and 3 months) and biomechanical properties, close to those of human arterial blood vessels
, Gelatin is a major factor to initiate cell adhesion, through luminal microstructure (micropores), cell contact and migration. Aging of PVA has to be taken account in future works, as well as the conditions of measure of the elastic modulus
