A method for isolation of human corneal endothelial cells by non-enzymatic harvesting and culturing of endothelial cells in vitro from critical density in a system consisting of extracellular matrix protein coated plastic dishes and growth factor enriched culture medium are used to generate expanded sub- populations of endothelial cells for cell replacement procedures or transplantation in denuded donor corneas. Special procedures are included in the process for the removal of the native corneal endothelium from the donor corneas and the seeding of the culture corneal endothelial cells onto the denuded corneas for transplantation purposes.

L'invention porte sur un procédé d'isolation des cellules endothéliales cornéennes humaines par récolte et culture non enzymatiques des cellules endothéliales in vitro à partir d'une densité critique dans un système comprenant des récipients en plastique recouverts de protéines matricielles extracellulaires et un milieu de culture enrichi du facteur de croissance et qui sont utilisés pour générer des sous-populations étendues de cellules endothéliales en vue de remplacer ou de transplanter de cellules dans des cornées dénudées de donneurs. L'invention porte également sur des procédures spécifiques incluses dans le processus de retrait de l'endothélium cornéen natif des cornées des donneurs et dans l'ensemencement des cellules endothéliales cornéennes de culture sur les cornées dénudées à des fins de for transplantation.
