Fig. 4.
Non-radioactive in situ hybridization of cryosections from adult mouse eye. (A) Lens and attached lens epithelium hybridized to a Cx23 anti-sense probe of complete Cx23 cDNA. Strong staining can be seen in the nuclei of lens fiber and lens epithelial cells that start to be integrated as lens fibers (LF), whereas the lens epithelium (LE) shows less staining. (B) Lens and lens epithelium hybridized to sense control probe for comparison. Bars: 100 μm.
