Fig. 8. The syncytial region expands during postnatal development. Fluorescence within living lenses from one-day-old (A), one-month-old (B) and six-month-old (C) hemizygous TgN(GFPU)5Nagy mice was imaged in the equatorial plane by confocal microscopy. Although the uniformly labeled lens core expands with age, the thickness of the variegated layer at the periphery (arrows) thins slightly over this period. The fluorescence in the center of the oldest lenses appears to be diminished with respect to the cortical cells. Bar, 250 µm.
