Figure 5. Fiber organization in 8-week-old lenses. A: Wild-type (WT) lenses retain well-organized, radially stacked rows of fiber cells in 8-week-old lenses. B: Disordered fiber cell regions are no longer commonly observed in connexin 50 (Cx50) knockout (KO) lenses at 8 weeks. C: Eight-week-old knock-in (Ki) lenses showed typical organization of overlaid fibers. Scale bar: 10 μm.
