On periodicity and directionality of somitogenesis.
Aulehla A, Pourquié O. Aulehla A, et al. Anat Embryol (Berl). 2006 Dec;211 Suppl 1:3-8. doi: 10.1007/s00429-006-0124-y. Epub 2006 Sep 21. Anat Embryol (Berl). 2006. PMID: 17024300 Review.
It is currently thought that the mechanism underlying somitogenesis is linked to a molecular oscillator, the segmentation clock, and to gradients of signaling molecules within the paraxial mesoderm. ...

Oscillating signaling pathways during embryonic development.
Aulehla A, Pourquié O. Aulehla A, et al. Curr Opin Cell Biol. 2008 Dec;20(6):632-7. doi: 10.1016/j.ceb.2008.09.002. Epub 2008 Oct 23. Curr Opin Cell Biol. 2008. PMID: 18845254 Review.
In mouse, this process is thought to be largely controlled by a cyclic signaling network involving the Notch, FGF, and Wnt pathways. ...These discoveries indicate that oscillatory signaling activities during embryonic development might serve a more general function …

Wnt3a plays a major role in the segmentation clock controlling somitogenesis.
Aulehla A, Wehrle C, Brand-Saberi B, Kemler R, Gossler A, Kanzler B, Herrmann BG. Aulehla A, et al. Dev Cell. 2003 Mar;4(3):395-406. doi: 10.1016/s1534-5807(03)00055-8. Dev Cell. 2003. PMID: 12636920
Somitogenesis involves a molecular oscillator, the segmentation clock, controlling periodic Notch signaling in the PSM. Here, we establish a novel link between Wnt/beta-catenin signaling and the segmentation clock. ...We propose that the segmentation clock is establ …

Segmentation in vertebrates: clock and gradient finally joined.
Aulehla A, Herrmann BG. Aulehla A, et al. Genes Dev. 2004 Sep 1;18(17):2060-7. doi: 10.1101/gad.1217404. Genes Dev. 2004. PMID: 15342488 Review.
The vertebral column is derived from somites formed by segmentation of presomitic mesoderm, a fundamental process of vertebrate embryogenesis. ...The Notch signaling pathway is linked to the oscillator and plays a decisive role in inter- and intrasomitic boundary fo …

Signaling gradients during paraxial mesoderm development.
Aulehla A, Pourquié O. Aulehla A, et al. Cold Spring Harb Perspect Biol. 2010 Feb;2(2):a000869. doi: 10.1101/cshperspect.a000869. Cold Spring Harb Perspect Biol. 2010. PMID: 20182616 Free PMC article. Review.
A beta-catenin gradient links the clock and wavefront systems in mouse embryo segmentation.
Aulehla A, Wiegraebe W, Baubet V, Wahl MB, Deng C, Taketo M, Lewandoski M, Pourquié O. Aulehla A, et al. Nat Cell Biol. 2008 Feb;10(2):186-93. doi: 10.1038/ncb1679. Epub 2007 Dec 23. Nat Cell Biol. 2008. PMID: 18157121 Free PMC article.
This process involves a molecular oscillator--the segmentation clock--whose signal is translated into a spatial, periodic pattern by a complex signalling gradient system within the presomitic mesoderm (PSM). ...In contrast, we show that the Wnt-signalling gra …

Dynamic signal encoding--from cells to organisms.
Sonnen KF, Aulehla A. Sonnen KF, et al. Among authors: aulehla a. Semin Cell Dev Biol. 2014 Oct;34:91-8. doi: 10.1016/j.semcdb.2014.06.019. Epub 2014 Jul 5. Semin Cell Dev Biol. 2014. PMID: 25008461 Free article. Review.
Dynamic expression of lunatic fringe suggests a link between notch signaling and an autonomous cellular oscillator driving somite segmentation.
Aulehla A, Johnson RL. Aulehla A, et al. Dev Biol. 1999 Mar 1;207(1):49-61. doi: 10.1006/dbio.1998.9164. Dev Biol. 1999. PMID: 10049564
In addition, we show that lunatic fringe is expressed in a highly dynamic manner in the chick segmental plate prior to somite formation and that lunatic fringe expression cycles autonomously with a periodicity of somite formation. ...The demonstration of a dy …
