β1-integrin null lenses retain the lens capsule A, B) Immunofluorescent staining of collagen IV (red) in the wildtype (A) and β1-integrin null (B) 16.5 dpc lens capsule C, D) Immunofluorescent staining of laminin (red) in the wildtype (C) and β1-integrin null (D) 16.5 dpc lens capsule. E, F) Periodic acid-Schiff staining (pink) of the newborn lens capsule (arrows) from wildtype (E) and β1-integrin null (F)mouse lenses showing that the lens capsule is retained even in areas denuded of lens epithelial cells (*). Abbreviations; e-lens epithelium; f- lens fiber cells. Panels A-D: scale bar= 77 μm. Panels E, F: scale bar =20 μm.
