The process of gastrulation is a pivotal step in the formation of the vertebrate body plan. The
primary function of gastrulation is the correct placement of precursor tissues for subsequent …

Vertebrate embryogenesis entails an exquisitely coordinated combination of cell
proliferation, fate specification and movement. After induction of the germ layers, the blastula …

We report the isolation of mouse cerberus-like (cer-l), a gene encoding a novel secreted
protein that is specifically expressed in the anterior visceral endoderm during early …

One of the major challenges of developmental biology is understanding the inductive and
morphogenetic processes that shape the vertebrate embryo. In a large-scale genetic screen …

Knowledge of the development and evolution of the neural crest sheds light on many of the
oldest unanswered questions in developmental biology. What is the role of germ layers in …

Technical advances are radically altering our concepts of normal prenatal craniofacial
development. These include concepts of germ layer formation, the establishment of the …

The evolutionary advent of uterine support of embryonic growth in mammals is relatively
recent. Nonetheless, striking differences in the earliest steps of embryogenesis make it …

We cannot catechise our stony ichthyolites, as did the necromantic lady of the Arabian
Nights did the coloured fishes of the lake which had once been a city, when she touched …

Cnidarians are fascinating creatures at the base of metazoan evolution possessing an
almost unlimited regeneration capacity that has attracted the interest of researchers, from …

Vertebrate segmentation has been proposed as an evolutionary inheritance either from
some metameric protostome or from a more closely related deuterostome. To address this …
