Fig. 4. Comparison of the expression patterns of XHEN1, XLMO-3, XNGNR- 1 and N-tubulin. (A-J) Stage 14, 25 and 35 Xenopus embryos were hybridized with probes for XLMO-3, XHEN1, X-NGNR-1 and N-tubulin. Embryos are shown in a dorsal (stage 14), dorsal-lateral (stage 25) or lateral (stage 35) view, with anterior to the left. At stage 14, XLMO-3 and XHEN1 are expressed only in two domains which will become interneurons (I) and motoneurons (M) of spinal cord, while X-NGNR-1 and N-tubulin are expressed also in the domains which will form sensory neurons (S) besides of these two medial domains. At stage 25, the expression patterns for all four probes are very similar. At stage 35, XHEN1 is only expressed in the brain region. (K,L) Transverse sections of Xenopus embryos hybridized with probes for XHEN1 and XLMO-3 at stage 20. In the neural tube, both of XHEN1 and XLMO-3 are located in the ventral part of spinal cord which is formed by interneurons and motoneurons. Image published in: Bao J et al. (2000) Copyright © 2000.
