  • Human conjunctival epithelial cell lines with an extended life span
    Patent number: 6030789
    Abstract: The present invention provides two human conjunctival epithelial cell lines with an extended life span, designated HC0597 and HC0708, and methods for producing such cell lines. These conjunctival cell lines can be cultured as stratified 3-dimensional (3-D) cultures. In turn, the 3-D cultures can be used as tissue- and species-specific cellular models of the human conjunctival ocular surface. These human conjunctival cultures are particularly useful, for example, in product safety evaluations to test products for their eye irritation potential.
