Isolation and Characterization of Human Goblet Cells in Vitro: Regulation of Proliferation and Activation of Mitogen-Activated Protein Kinase by EGF and Carbachol
The epithelium of the conjunctiva is a non-keratinizing stratified squamous epithelium1 Goblet cells, highly specialized epithelial cells, are located in the apical surface of the conjunctiva between the layers of stratified epithelium.2 These cells are primarily responsible for the secretion of the inner mucous layer of the tear film, thereby providing a physical and chemical barrier that hydrates the conjunctiva and protects it from exposure to other injurious agents. Abnormal mucin secretion (either overproduction or underproduction) by goblet cells can eventually lead to deterioration of the ocular surface.
