We have compared the expression of the murine genes En-1,En-2, and in-1 during development by in situ hybridization. Expression of all three genes was first detected at 8.0 days in overlapping bands of the anterior neural folds. By 12.0 days the expression patterns diverged. En-1 and En-2 were expressed in a similar ring of cells in the central nervous(More)
We have raised an antiserum, designated alpha Enhb-1, to a portion of the mouse En-2 protein containing the homeodomain. The antiserum detects both the En-1 and En-2 proteins in mouse, chick and Xenopus embryos by Western blot analysis. Using whole-mount immunohistochemistry, combined in some cases with scanning electron microscopy, we have examined the(More)
The two mouse genes, En-1 and En-2, that are homologs of the Drosophila segmentation gene engrailed, show overlapping spatially restricted patterns of expression in the neural tube during embryogenesis, suggestive of a role in regional specification. Mice homozygous for a targeted mutation that deletes the homeobox were viable and showed no obvious defects(More)
We have examined the pattern of expression of the homeo box-containing gene En-2 during mouse embryogenesis using in situ hybridization. Transcripts were first detected in the neural folds of 8.0-day, 5-somite embryos, and expression continued throughout development into adulthood. Hybridization occurred only in the central nervous system (CNS) and was(More)
