Single ISH of pitx2a at 48 hpf. a Wild-type control embryo showing expression of pitx2a in the developing brain and 5th branchial arch where pharyngeal tooth development occurs. b dax1 MO2-injected embryo showing unchanged expression of pitx2a. dax1 MO3-injected embryos showed a similar unchanged pitx2a expression pattern.

ISH of DAX1 on human dental tissue specimens. a Normal dental epithelium with the developing enamel organ. Arrows indicate ameloblasts. b Benign ameloblastoma tumor. Arrows indicate purple-stained ameloblasts expressing DAX1. c Malignant ameloblastoma tumor with numerous clusters of purple-stained ameloblasts infiltrating normal dental tissue.
