Background The corneal epithelium converges at the peripheral zone (limbus) with the
conjunctival epithelium, forming a continuous sheet with phenotypically distinct regions--
central, limbal, and conjunctival. The epithelial basement membrane (EBM) is important for
corneal functions and cell adhesion, but its regional composition is poorly understood.

Background
The corneal epithelium converges at the peripheral zone (limbus) with the conjunctival epithelium, forming a continuous sheet with phenotypically distinct regions--central, limbal, and conjunctival. The epithelial basement membrane (EBM) is important for corneal functions and cell adhesion, but its regional composition is poorly understood. Current literature is controversial as to the occurrence of type IV collagen in the cornea. The aim of this study was to investigate in detail corneal basement membrane (BM) composition and correlate it with the differentiation state of contributing cells.
