HoxB9 = Xlhbox6; posterior spinal chord

HoxB9 (=Xlhbox6), nucleic acid.

Cloned by Colin Sharpe et al. Expressed in the posterior spinal chord. Note, only neural specific at tailbud stages. At least at early and midneurula, there is a significant amount of expression in the dorsal mesoderm (more than HoxD1). These images are from Francesca Mariani and Richard Harland.
