Abstract:This is the first description of cultured RCEC grown on permeable support. Many of its properties mimic those described in the intact corneal epithelium. Even though its electrical tightness is less than that of the intact cornea, the transcellular permeability to lipophilic beta-antagonists is comparable to the isolated preparation. Therefore, this model will facilitate characterization of ocular permeation mechanisms of hydrophobic drugs whose route of permeation is transcellular.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
