How are cells instructed to form somite boundaries by the zebrafish segmentation clock?

Olivier François Venzin

In vertebrate embryos, the elongating body axis is patterned via the sequential and rhyth-mic production of segments from a posterior unsegmented tissue called the presomitic mesoderm (PSM). This process is controlled by a population of cellular oscillator ...

Reaction wavefront theory of notochord segment patterning

Andrew Charles Oates

The vertebrate axis is segmented into repetitive structures, the vertebrae. In fish, these segmented structures are thought to form from the paraxial mesoderm and the adjacent notochord. Recent work revealed an autonomous patterning mechanism in the zebraf ...

ProNodal acts via FGFR3 to govern duration of Shh expression in the prechordal mesoderm

Daniel Constam

The secreted glycoprotein sonic hedgehog (Shh) is expressed in the prechordal mesoderm, where it plays a crucial role in induction and patterning of the ventral forebrain. Currently little is known about how Shh is regulated in prechordal tissue. Here we s ...

Polarity establishment, asymmetric division and segregation of fate determinants in early C. elegans embryos

Pierre Gönczy

Polarity establishment, asymmetric division, and acquisition of cell fates are critical steps during earlydevelopment. In this review, we discuss processes that set up the embryonic axes, with an emphasis onpolarity establishment and asymmetric division. W ...

Locomotion through Reconfiguration based on Motor Primitives for Roombots Self-Reconfigurable Modular Robots

Auke Ijspeert, Alexander Spröwitz, Massimo Vespignani, Rico Möckel, Stéphane Bonardi

We present the hardware and reconfiguration experiments for an autonomous self-reconfigurable modular robot called Roombots (RB). RB were designed to form the basis for self-reconfigurable furniture. Each RB module contains three degrees of freedom that ha ...

Biocomposite Hydrogels with Carboxymethylated, Nanofibrillated Cellulose Powder for Replacement of the Nucleus Pulposus

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban, Ana Borges de Couraça, Fabien Duc

Biocomposite hydrogels with carboxymethylated, nanofibrillated cellulose (c-NFC) powder were prepared by UV polymerization of N-vinyl-2-pyrrolidone with Tween 20 trimethacrylate as a cross-linking agent for replacement of the native, human nucleus pulposus ...

Role of Bicaudal-C in Left-Right Axis Formation and Kidney Morphogenesis

The KH domain RNA binding protein Bicaudal-C is known to play a role in anterior-posterior (AP) patterning in Drosophila by acting on oskar mRNA. In mammals, its expression is induced at late gastrulation in the mesodermal layer of the ventral node. Renal ...
