More than patterning--Hox genes and the control of posterior axial elongation.
Hox genes are well known for their evolutionarily conserved role in patterning the body axis. Now, Young et al. in this issue of Developmental Cell present evidence that at least in mouse embryos Hox genes do more, namely controlling the process of axis formation itself.
