Fig. 2. The pattern of XIF3 expression in the later embryo. (A) In the late tailbud (stage 28) expression in the Vllth cranial nerve is now apparent and within the anterior neural tube expression of XIF3 resolves into patches of high and low expression along the A-P axis. (B) Lateral view showing expression in the Vth and (arrowed) Vllth cranial ganglia and in the eye. (C) By stage 36/37 expression in the caudal primary neurons has almost completely disappeared, though staining in the cranial ganglia remains strong. Within the CNS, XIF3 is now clearly expressed in distinct domains. There is a domain in the forebrain that lies beneath the nasal pits (arrowhead) and another at the midbrain-hindbrain boundary (arrow). Within the hindbrain expression is mainly confined to rhombomeres 2,4 and 6. (D) A transverse section through a stage 36/37 embryo shows that XIF3 expression within the even rhombomeres is confined to a ventro-Iateral domain.
