Fig. 2. Expression of XHox11 and XHox11L2 during embryogenesis, assayed by whole-mount in situ hybridization. A, B, C, F, G: Photographed at 325. D,E: Photographed at 380. A: Stage 25 embryo showing XHox11 expression in the visceral arches, cranial nerves, hindbrain, and spinal cord. B: Stage 24 embryo stained for XHox11L2. Notice expression in the trigeminal ganglia and spinal cord. C: Dorsal view of a stage 24 embryo assayed for XHox11L2 expression. D: XHox11 expression in the branchial arches, V, VII/VIII, IX, and X cranial ganglia, and the hindbrain of a stage 30 embryo. E: A stage 30 embryo showing XHox11L2 expression in the V, VII/VIII, IX, and X cranial ganglia, as well as in the spinal cord. F: XHox11 expression at stage 37 is restricted to the branchial arches, hindbrain, and cranial nerves VIII and X. G: A stage 37 embryo showing expression of XHox11L2 in the hindbrain, spinal cord, and cranial nerves V, IX, and X. hb, hindbrain; sc, spinal cord; va, visceral arches; V, trigeminal ganglia; VII, facial ganglia; VIII, acoustic ganglia; IX, glossopharyngeal ganglia; X, vagus ganglia. |
