The ventral nerve cord of arthropods is characterised by the organisation of major axon tracts in a ladder-like pattern. The individual neuromeres are connected by longitudinal connectives whereas the contra-lateral connections are brought ...

We have used two complementary cell labeling techniques to investigate dorsal mesoderm formation in Xenopus laevis and Hymenochirus boettgeri. Epithelial grafts from fluorescently labeled donors into unlabeled hosts demonstrate that in Xeno...
Developmental expression of Ultraspiracle proteins in the epidermis of the tobacco hornworm, Manduca sexta, during larval life and the onset of metamorphosis [0.03%]

During the final two larval instars, a changing pattern of three Ultraspiracle (Usp) proteins (50.5, 52.5, and 57 kDa) was detected in immunoblots of the dorsal abdominal epidermis of the tobacco hornworm, Manduca sexta, by a monoclonal ant...
Notch homologue from Halocynthia roretzi is preferentially expressed in the central nervous system during ascidian embryogenesis [0.03%]

We describe here the primary structure of HrNotch, an ascidian homologue of the Drosophila neurogenic gene Notch. HrNotch transcripts encode a protein of 2352 amino acids and share the principal features of the Notch gene family: extracellu...

In order to facilitate in situ detection of biomolecules in large sample series the processing of whole-mount specimens has been automated. A freely programmable liquid handling system is described by which embryos or similar biological mat...
Segment-specific expression of the gap junction gene connexin31 during hindbrain development [0.03%]

During segmentation of the mouse hindbrain (d8.0-8.5 pc), expression of the gap junction gene connexin31 (cx31) is precisely restricted to rhombomeres (r) 3 and 5. Shortly afterwards, during the turning process, cx31 expression in rhombomer...
A rat homeobox gene, rNKx-2.5, is a homologue of the tinman gene in Drosophila and is mainly expressed during heart development [0.03%]

We report the cloning of a rat homeobox-containing gene, rNkx-2.5, and investigation of its expression in adult tissues and during embryonic development. The rNkx-2.5 gene is a homologue of the tinman gene in Drosophila. Both genes share an...

Using a homology-based cDNA cloning strategy we have identified a member of the fibulin family in the zebrafish Danio rerio. The deduced sequence of this protein is highly homologous to mammalian fibulins. Two variants of this protein have ...

During vertebrate embryonic development, pairs of metameric units, the somites, bud off at the cranial end of the paraxial mesoderm. The somites soon obtain cranio-caudal and dorso-ventral polarity. Establishment of dorso-ventral and medio-...
