Abstract

La présente invention concerne un procédé de formation d'une structure cardiovasculaire en culture. Ledit procédé comprend l'application d'une force mécanique à une population cellulaire en culture de manière à former une structure cardiovasculaire. Dans certains modes de réalisation, la force mécanique est produite dans un milieu de culture par un flux de liquide pulsatile avec un composant rétrograde. La population cellulaire peut comprendre des cellules souches ou des cellules différenciées, ou des combinaisons des deux. Dans certains modes de réalisation, une valvule cardiovasculaire est formée. L'invention porte en outre sur des échafaudages pour le support et la croissance de la population cellulaire, et sur des bioréacteurs comprenant lesdits échafaudages.
