Fig. 7. Expression patterns of Shh, Gli1, Ptch and Six1. (A-F)
Expressions of Shh (A,B), Gli1 (C,D) and Ptch (E,F)
in wild-type (A,C,E) and Six1/ (B,D,F)
embryos at E10.5. (G,H) Expression of Six1 in wild-type (G) and
Shh/ (H) otic vesicles at E10.5. Three pairs
of wild-type and Six1/ embryos and three
pairs of wild-type and Shh/ embryos were
analyzed and virtually the same results obtained. d, dorsal; la, lateral. fp,
floor plate; nc, notochord. Scale bars: 100 µm.
