Abstract: A composition for ex vivo culture of corneal endothelial cell and a method for used the composition are disclosed. The composition or the method is applied to ex vitro culture of the corneal endothelial cell to maintain the corneal endothelial cell in a hexagonal phenotype, and to prevent the corneal endothelial cell from endothelial-mesenchymal transformation (EnMT). Therefore, the corneal endothelial cell can maintain normal phenotype and function and can be used in the further application. The composition at least comprises an effective concentrated matrix metalloproteinase inhibitor (MMPI).

Abstract: The disclosure relates to a platform of using zebrafish in screening candidates for treating and/or preventing myopia and keratoconus disease. The disclosure is mainly based on that Lumican, one of several SLRPs, plays an important role in the regulation of fibrillogenesis or the genes affecting the size of eyeballs in zebrafish, in addition to playing an important role in clinical myopia. Therefore, the disclosure uses the established zebrafish model to further identify the drugs affecting the expression of lumican and collagen fibrillogenesis, and/or the regulation of eyeball size. These drugs are potential candidates for treating myopia and/or keratoconus disease.
