A striking property of vertebrate embryos is the emergence of a conserved body plan across
a wide range of organisms through the process of gastrulation. As the body plan unfolds, …

Development encompasses processes that occur at multiple length scales, including gene-regulatory
interactions, cell movements and reorganization, cell signalling and growth. It is …

During embryonic development, the timing of events at the cellular level must be coordinated
across multiple length scales to ensure the formation of a well-proportioned body plan. This …

Experimental Embryology is often referred to as a classical approach of developmental
biology that has been to some extent replaced by the introduction of molecular biology and …

During embryonic development, the timing of events at the cellular level must be coordinated
across multiple length scales to ensure the formation of a well-proportioned body plan. This …

Classical tissue recombination experiments performed in the chick embryo provide evidence
that signals operating during early limb development specify the position and identity of …

In situ hybridization (ISH) methods remain the most popular approach for profiling the
expression of a gene at high spatial resolution and have been broadly used to address many …

Timing is a fundamental feature of embryogenesis: the embryos of a given species develop
with reproducible timing and a precise ordering of events. The underlying mechanisms that …

Flight is a triumph of evolution that enabled the radiation and success of birds. A crucial step
was the development of forelimb flight feathers that may have evolved for courtship or …

In vertebrate embryos, a process called somitogenesis lays the foundations of the adult
spine. This process involves elongation and segmentation of the paraxial mesoderm to form …
