Compartment-dependent activities of Wnt3a/β-catenin signaling during vertebrate axial extension

Extension of the vertebrate body results from the concerted activity of many signals in the posterior embryonic end. Among them, Wnt3a has been shown to play relevant roles in the regulation of axial progenitor activity, mesoderm formation and somitogenesis. However, its impact on axial growth remains to be fully understood. Using a transgenic approach in the mouse, we found that the effect of Wnt3a signaling varies depending on the target tissue. High levels of Wnt3a in the epiblast prevented formation of neural tissues, but did not impair axial progenitors from producing different mesodermal lineages. These mesodermal tissues maintained a remarkable degree of organization, even within a severely malformed embryo. However, from the cells that failed to take a neural fate, only those that left the epithelial layer of the epiblast activated a mesodermal program. The remaining tissue accumulated as a folded epithelium that kept some epiblast-like characteristics. Together with previously published observations, our results suggest a dose-dependent role for Wnt3a in regulating the balance between renewal and selection of differentiation fates of axial progenitors in the epiblast. In the paraxial mesoderm, appropriate regulation of Wnt/β-catenin signaling was required not only for somitogenesis, but also for providing proper anterior-posterior polarity to the somites. Both processes seem to rely on mechanisms with different requirements for feedback modulation of Wnt/β-catenin signaling, once segmentation occurred in the presence of high levels of Wnt3a in the presomitic mesoderm, but not after permanent expression of a constitutively active form of β-catenin. Together, our findings suggest that Wnt3a/β-catenin signaling plays sequential roles during posterior extension, which are strongly dependent on the target tissue. This provides an additional example of how much the functional output of signaling systems depends on the competence of the responding cells.

Chemical composition and K-Ar age of rocks from the northern Sea of Japan

The Middle Paleozoic complex consists of terrigenous and volcanogenic materials metamorphized in greenschist facies. Clastic rocks have arkosic composition and are formed by alteration of basalts and metamorphic rocks. Metaeffusives were formed from basaltoid products of oceanic tholeiite magma indicating that underwater rise structures of the northern Sea of Japan were emplaced on the oceanic crust.

Monumens de l'histoire de France, en estampes et dessins ...

The present 30 volumes seem to have remained with the Dukes of Leuchtenberg, until the ducal library was acquired for sale in 1935 by the dealers Ulrich Hoepli (Milan) and Braus-Riggenbach (Basel). The volumes are not complete, as leaves have been wholly or partly removed throughout; this is particularly evident in preliminary volumes 2 and 10 and volume 75. Prints and the relatively small number of drawings are mostly French, with some German, Dutch and English, and are mostly of the 17th or 18th centuries. They are mounted generally on rectos of leaves, often with hand-written captions. Large prints are occasionally bound in directly; these are often folded. The engraved general title page (bearing the date 1788) appears at the beginning of each volume; below the printed title a hand-written volume number and brief title describing the volume's contents usually appear. In many volumes the title leaf is followed by a hand-written contents leaf listing the section titles, which are also written individually throughout the volume on leaves with etched decorative frames. Sections are numbered continuously throughout the work as a whole. Numbering of the leaves, when present, appears in black ink within each volume at top center recto. Printmakers include B. & J. Audran, Francesco Bartolozzi, Abraham Bosse, Stefano della Bella, Jacques Callot, François Chéreau, Wenceslaus Hollar, Romeyn de Hooghe, Raymond La Fage, Sébastien Le Clerc, Pierre Lepautre, Claude Mellan, Bernard Picart, and Simon Thomassin. There are also early color prints by Gautier-Dagoty and Jean-Baptiste Morret.
