Fig. 6 Induction of ptc1, myoD and nk2.2 expression by shh in the brain and early somitogenesis stage embryos. (A,C) Lateral views of ptc1 expression in the brain of 27-hour-old embryos. (A) Uninjected control embryo. (C) shh-injected embryo. (B,D) Lateral views of nk2.2 expression in the brain of 27-hour-old embryos. (B) Uninjected control embryo. (D) shh-injected embryo. Arrowheads in C, D show the telencephalon which is devoid of ectopic ptc1 and nk2.2 expression. (E,G) Dorsal views of ptc1 expression in flat preparations of embryos at early somitogenesis. (E) Uninjected embryo. (G) shh-injected embryos. No ectopic ptc1 expression was detected in the ectoderm. (F,H) Dorsal views of myoD expression in flat preparations of embryos at early somitogenesis. (F) Uninjected embryo. (H) shh-injected embryo.
