Role of the zebrafish trilobite locus in gastrulation movements of convergence and extension.

Abstract excerpt

Convergence and extension are gastrulation movements that participate in the establishment of the vertebrate body plan. Using new methods for quantifying convergence and extension movements of cell groups, we demonstrate that in wild-type embryos, dorsal convergence of lateral cells is initially slow, but speeds up between the end of the gastrula period and early segmentation. Convergence and extension movements...
