Differential expression of integrin β1, integrin α-6, and Notch-1 in the human limbo-corneal epithelium. Immunofluorescent staining of integrin β1, integrin α-6, and Notch-1 on frozen sections of human cornea (left panels) and limbus (right panels). The arrow points to the positively labeled basal cells at the limbus (green fluorescence indicated FITC conjugated anti mouse/rat IgG and blue fluorescence demonstrates nuclear counterstain with DAPI).
