Analysis of a double mutant in the Hippo pathway transcription factors Yap1 and Wwtr1 reveals novel roles for these factors in posterior body formation and epidermal morphogenesis in the vertebrate embryo.

Pair-rule genes in the wasp Nasonia function as in Drosophila in patterning anterior segments, and similar to ancestral insects in patterning posterior segments, illustrating a mixed-mode transition state between short and long germ embryogenesis.

During vertebrate axial extension, the tail bud originates from the activation of a developmental module in a subset of axial progenitors, concurrent but different to gastrulation.

Very local molecular patterns impart precise changes in the local mechanics of individual cell-cell junctions.

The collinear activation of a subset of posterior Hox genes is responsible for establishing a Wnt/T activity gradient that is required to generate the complete body axis, and hence the full set of segments within a vertebrate embryo.

Analysing Myosin II unipolar planar polarisation with high spatial and temporal resolution during Drosophila axis extension reveals how tissue boundaries drive polarized cell intercalation while limiting cell mixing.

Cells know when to contribute to the maturing embryonic body axis by adjusting an internal timer to the conditions around them.

Inverse gradients of cell ingression and division in the epiblast allow the bipotent progenitors in the anterior streak to become the main progenitors for posterior axis formation from the tail bud.

Computational and theoretical biomechanical analysis reveals how actomyosin filaments and axial muscles conjugate their activity to realize a fourfold elongation during C. elegans embryogenesis, 4 hr just before hatching.

During intestinal development, apical PAR complex proteins keep apical domains and junctions continuous between cells as they divide and elongate, and ultimately build a continuous functional tube.
