This product is a specialized culture medium with clearly defined components and targeted high efficiency, designed to induce human pluripotent stem cells or limbal stem cells to differentiate into functionally mature corneal epithelial cells. It effectively mimics the in vivo microenvironment for corneal epithelial development and maintenance, thereby strongly activating the expression program of corneal epithelial-specific genes (such as KRT3 and KRT12). This successfully guides cells to acquire the typical morphology of corneal epithelial cells while significantly enhancing their barrier function and marker expression levels.
