Fig. 1. During the formation of the tail, N-CAM is expressed solely on neural tissues in Xenopus embryos. A shows a
phase-contrast image of a longitudinal cross section of a stage-22 embryo. B is the corresponding immunofluorescence
image obtained with rabbit N-CAM antibodies and goat anti-rabbit Ig antibodies linked to FITC. The cell membranes
of the neural tube are labelled, whereas the mononucleated muscle cells arranged in somites are not. C shows an
N-CAM immunofluorescence staining of a stage-25 embryo. The level of background fluorescence is high in B and C
due to the autofluorescence of yolk. D shows N-CAM immunofluorescence staining of a whole-mount strip of a stage-42
tadpole tail. The pigmented cells of the neuroepithelium do not stain, nor do the myotomal muscles separating each set
of axons. N, row of nuclei. Bar, 120^m in A-C and 100Um in D. Image published in: Kay BK et al. (1988) Copyright © 1988. Image reproduced with permission of the publisher and the copyright holder.
