Actively cycling cells are present in the central and germinative zones of the mouse lens epithelium. (A) Paraffin section of the eye of an adult mouse that had received a single intraperitoneal injection of BrdU followed 24 hours later by an injection of 3H-TdR. BrdU-labeled or 3H-TdR-labeled nuclei were detected in the central (c) and germinative (g) zones of the lens epithelium. (B) A portion of the central (c) zone within the solid rectangle is shown at higher magnification; note the lens epithelial cells with BrdU-labeled (red nuclei) and 3H-TdR-labeled nuclei (arrowhead). (C) A portion of the germinative (g) zone within the dashed rectangle is shown at higher magnification. Cells with BrdU-labeled and 3H-TdR-labeled nuclei (arrowheads) are more prevalent in this region.
