title: [Research progress of corneal epithelial basal cells and basement membrane].
abstract: The cylinder cells at the bottom of corneal epithelial cells are basal cells. Their cytoplasm contains keratin intermediate filament which is important in secretion of basement membrane. Corneal epithelial dysfunction due to diabetes or ocular surgery is intimately related with basal cell abnormality. Corneal epithelial basement membrane is a highly specific extracellular matrix which is made up of lamina lucida and lamina densa. It plays an extremely important role in renewal and restoration. Many ocular abnormalities and diseases have been described to relate to the corneal epithelial basement membrane, such as traumatic recurrent corneal erosion, corneal dystrophy and keratoconus.
