Fig. 9. Expression of Mab21l1 in Sey/Sey mutant embryos. In situ hybridization of wild-type (A,C,E) and Sey/Sey (B,D,F) frozen sections at 22-somite (A,B) and 35-somite stages (C-F). Mab21l1 expression is almost totally abolished at the 22-somite stage (B), and greatly reduced at the 35-somite stage in the Sey/Sey mutant embryos (D). However, the Mab21l2 expression level is basically identical between wild-type and Sey/Sey mutant embryos (E,F). Scale bars: 100 µm.
