Abstract
L'invention concerne une nouvelle structure d'emballage de cryoconservation efficace de tissus mammaliens récoltés et d'équivalents de tissus de culture obtenus par la technique in vitro. Le procédé selon l'invention consiste à immerger un tissu mammalien ou un équivalent de tissu de culture dans une solution cryoprotectrice, à agiter la solution cryoprotectrice et le tissu immergé de sorte que la solution cryoprotectrice pénètre efficacement dans le tissu, et à congeler le tissu à une vitesse de congélation très faible. Dans la phase de congélation, la formation de glace extracellulaire est induite par ensemencement. Le tissu cryoconservé peut être stocké pendant des périodes indéfinies avant d'être utilisé. L'équivalent de tissu de culture est un modèle in vitro du tissu humain équivalent tel que la peau ou la cornée, qui, une fois retiré du stockage peut être utilisé pour une transplantation ou un implant in vivo ou pour le titrage de composés in vitro.
