Hmx1 transcription in e10.5 day embryos. Whole mount RNA in situ hybridization (at 10.5× magnification) of an Hmx1 antisense riboprobe (see Methods) to a heterozygous (WT) embryo and dmbo/dmbo embryo is shown. E = eye; t = trigeminal ganglion; op = otic placode; a2 = second branchial arch; dr = dorsal root ganglion. The arrowhead indicates mesenchymal expression in the proximal region of 1st branchial arch caudal margin.
