Abstract
The cell behaviors associated with gastrulation in sea urchins have been well described. More recently, considerable progress has been made in elucidating gene regulatory networks (GRNs) that underlie the specification of early embryonic territories in this experimental model. This review integrates information from these two avenues of work. I discuss the principal cell movements that take place during sea urchin gastrulation, with an emphasis on molecular effectors of the movements, and summarize our current understanding of the gene regulatory circuitry upstream of those effectors. A case is made that GRN biology can provide a causal explanation of gastrulation, although additional analysis is needed at several levels of biological organization in order to provide a deeper understanding of this complex morphogenetic process.
期刊介绍：
Mechanisms of Development is an international journal covering the areas of cell biology and developmental biology. In addition to publishing work at the interphase of these two disciplines, we also publish work that is purely cell biology as well as classical developmental biology.
Mechanisms of Development will consider papers in any area of cell biology or developmental biology, in any model system like animals and plants, using a variety of approaches, such as cellular, biomechanical, molecular, quantitative, computational and theoretical biology.
Areas of particular interest include:
Cell and tissue morphogenesis
Cell adhesion and migration
Cell shape and polarity
Biomechanics
Theoretical modelling of cell and developmental biology
Quantitative biology
Stem cell biology
Cell differentiation
Cell proliferation and cell death
Evo-Devo
Membrane traffic
Metabolic regulation
Organ and organoid development
Regeneration
Mechanisms of Development does not publish descriptive studies of gene expression patterns and molecular screens; for submission of such studies see Gene Expression Patterns.
