title: Convergent extension: the molecular control of polarized cell movement during embryonic development.
abstract: During development, vertebrate embryos undergo dramatic changes in shape. The lengthening and narrowing of a field of cells, termed convergent extension, contributes to a variety of morphogenetic processes. Focusing on frogs and fish, we review the different cellular mechanisms and the well-conserved signaling pathways that underlie this process.
