Reconstruction of conjunctival epithelium-like tissue using a temperature-responsive culture dish.


ABSTRACT: To study the feasibility of engineering conjunctival epithelial cell sheets on a temperature-responsive culture dish for ocular surface reconstruction.Rabbit conjunctival epithelial cells (rCjECs) were cultured in DMEM/F-12 (1:1) medium. The morphology and phenotype of the rCjECs were confirmed with phalloidin staining, periodic acid-Schiff (PAS) staining, and immunocytochemistry. The rCjECs cultured on a temperature-responsive culture dish for 10 days produced confluent conjunctival epithelial cell sheets. Then, the phenotype, structure, and function of the conjunctival epithelial cell sheets were examined.The conjunctival epithelial cells were compact, uniform, and cobblestone shape. All cultured conjunctival epithelial cells were harvested as intact cell sheets by reducing the culture temperature to 20 °C. Conjunctival epithelial cells were stratified in four to five cell layers similar to the conjunctival epithelium. CCK-8 analysis, 5-bromo-2'-deoxyuridine (BrdU) staining, and the live and dead viability assay confirmed that viable proliferation cells were retained in the cell sheets. Immunohistochemistry for CK4, CK19, and MUC5AC showed the cell sheets still maintained characteristics of the conjunctival epithelium.A temperature-responsive culture dish enables fabrication of viable conjunctival epithelial cell sheets with goblet cells and proliferative cells. Conjunctival epithelial cell sheets will be promising for reconstruction of the conjunctival epithelium.
