<unk> s, also known as corneal epithelial stem<unk> s, are stem<unk> s located in the basal epithelial layer of the corneal limbus. They form the border between the cornea and the sclera. Characteristics of<unk> s include a slow turnover rate, high proliferative potential, clonogenicity, expression of stem<unk>  markers, as well as the ability to regenerate the entire corneal epithelium.<unk>  proliferation has the role of maintaining the cornea; for example, by replacing<unk> s that are lost via tears. Additionally, these<unk> s also prevent the conjunctival epithelial<unk> s from migrating onto the surface of the cornea.
