Figure Caption

Fig. 4 48 hpf embryos injected with anti-sense Col15a1 morpholinos (B) are almost similar to the embryos injected with Col15a1-Ms (A) except they are slightly shorter. Histological analysis of collagen XV morphants. Transversal sections of wild-type (C), Col15a1-Ms (D) and Col15a1-MO injected embryos at 48hpf. In Col15a1-MO, the peri-notochordal sheath is thinner compared to wild-type and control embryos. In 48 hpf collagen XV morphants, the muscular tissue is disorganized and horizontal myosepta are no visible. Neural tube and vessels are normal. (F, G) Lateral views of wild-type embryos (F) and Col15a1-MO embryos (G) at 48 hpf stained with antibodies to dystrophin to reveal the shape of myotomes. Contrary to wild type embryos (F), morphants (G) exhibit a U-shape of the myotomes. Magnification: A: x 200; B: x 200; C–E: x 400; F, G: x 300.
