B. lanceolatum Hox gene expression patterns. Expression profile of anterior (Hox1 and Hox3), central (Hox4 and Hox7), and posterior (Hox10) genes of the B. lanceolatum Hox cluster are shown in lateral views of amphioxus embryos from the gastrula stage (left-most panel) to the larval stage (48 h post fertilization, right panels). Whereas Hox1 was expressed in scattered cells in the epidermis (arrows in the Hox1 panels of the late neurula and pre-mouth larval stage), this was not clear for Hox3 and was definitely absent for Hox4. Blue arrows indicate the anterior limit of expression in the CNS. In all panels, dorsal is on the top and anterior is to the left. ND, non-detected signal. Scale bars = 100 μm.
