HCE-T Cells

The HCE-T cell line is derived from human corneal epithelial cells and has been immortalized by transfection with the plasmid RSV-T (pRSV-T). This plasmid carries an SV40 origin of replication (SV40 ori) and includes the SV40 early region genes along with the Rous sarcoma virus long terminal repeat (RSV-LTR). This genetic modification enables the HCE-T cells to bypass normal senescence, allowing for indefinite proliferation. Despite their immortalization, these cells retain many of the functional and phenotypic characteristics of primary corneal epithelial cells, including typical epithelial morphology, the ability to form adherent monolayers, and the expression of cytokeratins and other essential epithelial markers. As a result, HCE-T cells are an invaluable resource for in vitro ocular research. HCE-T cells are widely utilized to investigate various aspects of corneal epithelial biology, such as cell adhesion, migration, differentiation, and response to external stimuli, including therapeutic agents and environmental stressors. Their ability to mimic in vivo corneal conditions makes them highly relevant for studying corneal diseases like dry eye syndrome, keratitis, and corneal ulcers. These cells serve as an important model to explore disease mechanisms and test potential treatments. Additionally, HCE-T cells play a crucial role in drug development and testing for ophthalmic applications, offering a reliable platform to evaluate the safety and efficacy of new drugs and drug delivery systems. Their capacity for long-term culture allows for sustained research efforts, advancing the development of new therapies aimed at improving ocular health.
