The corneal epithelium is constantly exposed to external factors such as light, dust, and microorganisms, and the cells in this layer can become damaged over time. LSCs help to replenish these cells, keeping the cornea clear and functional.<\/p>\n<h3 data-start=\"829\" data-end=\"862\"><span class=\"ez-toc-section\" id=\"Function_of_Limbus_Stem_Cells\"><\/span>Function of Limbus Stem Cells<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p data-start=\"864\" data-end=\"1203\">Limbus stem cells serve as the &#8220;repair&#8221; system for the cornea. When corneal cells become damaged or aged, the LSCs divide and generate new epithelial cells to replace them. These new cells then migrate toward the center of the cornea, promoting healing and preventing the cornea from becoming opaque, which could lead to vision impairment.<\/p>\n<p data-start=\"1205\" data-end=\"1469\">In addition to their regenerative properties, limbus stem cells also help in maintaining the overall structural integrity of the corneal tissue. Without healthy LSCs, the cornea would lose its ability to repair itself, leading to various eye conditions, including:<\/p>\n<ul data-start=\"1471\" data-end=\"1726\">\n<li data-start=\"1471\" data-end=\"1726\">\n<p data-start=\"1473\" data-end=\"1726\"><strong data-start=\"1473\" data-end=\"1511\">Limbal stem cell deficiency (LSCD)<\/strong>: This is a condition where there is insufficient stem cell function in the limbus, resulting in corneal scarring, opacity, and potential vision loss.
