Figure 3. BMP5 expression in a stage 15 T. scripta embryo.
BMP5 expression is associated with the developing vertebrae in the cervical region and the newly formed somites in the tailbud. In addition, BMP5 is expressed in the anterior and posterior margins of the autopod, and in the apical ectodermal ridge of the developing limb buds (A and B antisense, C sense).
