Corneal epithelial cell and conjunctival epithelial cell

Corneal and conjunctival epithelial cells are specialized stratified squamous epithelial cells that form the outermost layer of the cornea and conjunctiva, respectively. The corneal epithelium is nonkeratinized and provides a smooth, transparent surface crucial for light transmission and the maintenance of optical quality. It acts as a barrier to pathogens and mechanical injury, participating in wound healing through rapid cell division and migration[1][2][3]. Conjunctival epithelial cells line the inner eyelid and the white of the eye; they include goblet cells that secrete mucin, contributing to tear film stability. While sharing some molecular markers, corneal and conjunctival epithelia are governed by distinct stem cell populations and display divergent gene expression profiles—notably in keratin expression—reflecting their specialized functions in ocular surface health and disease[2][3][4]. Note: This entry represents cell populations and does not correspond to a canonical molecular drug target (such as a receptor, enzyme, or channel). For structured data purposes in a pharmacological context, this entry would be flagged as “incorrect” for molecular targeting, and more specific molecular or protein targets expressed by these cell types should be identified (e.g., individual keratin genes, integrins, or stem cell markers)[2][3][4][6].
