Fig. 1. Expression of Fyn in developing embryos, as revealed by whole-mount in situ hybridization. (A–C) Lateral view of the embryos
at stages 20, 26 and 32, respectively, with the anterior to the left. Note in (A) that strong Fyn signals (arrowheads) are detectable in
the brain region of neural tube and that medium to weak signals (arrows) are detectable in all the length of remaining neural tube.
(D,E) Cross-sections of the stained embryo at the levels of (D) hindbrain and (E) spinal cord. (F) A section through the spinal cord
showing location of Rohon–Beard neurons (arrows) that are labeled using a contactin antisense probe. fb, forebrain; hb, hindbrain;
mb, mid-brain; n, notochord; sp., spinal cord. Bars, 100 μm. |
