Constructing an in vitro cornea from cultures of the three specific corneal cell types

In Vitro Cell Dev Biol Anim. 1999 Oct;35(9):515-26. doi: 10.1007/s11626-999-0062-0.


This paper presents a reliable method for establishing pure cultures of the three types of corneal cells. This is believed to be the first time, corneal cells have been cultured from fetal pig corneas. Cell growth studies were performed in different media. Subcultures of the three corneal cell types were passaged until the 30th generation without their showing signs of senescence. For engineering an in vitro cornea, corneal epithelial cells were cultured over corneal stromal cells in an artificial biomatrix of collagen with an underlying layer of corneal endothelial cells. The morphology, histology, and differentiation of the in vitro cornea were investigated to determine the degree of comparability to the cornea in vivo. The in vitro construct displayed signs of transition to an organotypic phenotype of which the most prominent was the formation of two basement membranes.
