Figure 1 CS expression in the Xenopus embryonic optic pathway. Confocal micrographs of
transverse sections of stage 37/38 embryos immunostained for endogenous CSs. (A) CS immunostaining,
as visualized by the CS-56 antibody, is localized in the basal lamina surrounding the
diencephalon and to a lesser extent in the neuropil (Np) and the neuroepithelium (Ne). There is also
abundant CS expression in the mesenchyme outside the nervous system. Arrowheads represent the
area enlarged in panel E. (B–D) Specific expression of the CS subtypes. (B) Chondroitin is
expressed at higher levels in the neuropil than in the neuroepithelium. (C) Chondroitin-4-sulfate is
expressed in both the neuropil and neuroepithelium. (D) Chondroitin-6-sulfate is expressed primarily
in the neuroepithelium and at a lower degree in the neuropil. (E) A double-labeled section
showing HRP-filled RGC axons (red) growing in the CS-rich region (green) of the diencephalic
neuropil. Dorsal is up. Scale bar is 50 m in (A)–(D) and 25 m in (E). Image published in: Walz A et al. (2002) Copyright © 2002. Image reproduced with permission of the Publisher. Larger Image Printer Friendly View |
