Fig. 3. Quantitative assessment of axonal regeneration. (A-D) Photomicrographs of FluoroGold-labeled RGCs in whole-mount retinas from injured and uninjured wt and Bcl-2tg mice on day 11 after optic nerve crush. Bar, 50 µm. (E) Number of retrogradely labeled RGCs in the retinal whole-mounts of wt and Bcl-2tg mice that underwent optic nerve crush (injured) or a sham procedure. (F) Distance of axonal regeneration on days 1-4. Values are mean±s.e.m.
