Mesoderm arises at gastrulation and contributes to both the mouse embryo proper and its
extra‐embryonic membranes. Two‐photon live imaging of embryos bearing a keratin reporter …

… (E) The method for measuring the area of the neural crest domain. The neural crest area on
… First, we checked the distributions of E and N cadherins, and that of laminin, a component of …

Mitosis is a key process in development and remains critical to ensure homeostasis in adult
tissues. Besides its primary role in generating two new cells, cell division involves deep …

At gastrulation, a subpopulation of epiblast cells constitutes a transient posteriorly located
structure called the primitive streak, where cells that undergo epithelial–mesenchymal …

Pseudostratified epithelia (PSE) are a common type of columnar epithelia found in a wealth
of embryonic and adult tissues such as ectodermal placodes, the trachea, the ureter, the gut …

The mechanical properties of the different germ layers of the early mammalian embryo are
likely to be critical for morphogenesis. Cytoskeleton components (actin and myosin, …

During the epithelial-mesenchymal transition driving mouse embryo gastrulation, cells at
the primitive streak divide more frequently that in the rest of the epiblast, and half of those …

The epiblast, a pseudostratified epithelium, is the precursor for the three main germ layers
required for body shape and organogenesis: ectoderm, mesoderm, and endoderm. At …

During early mouse embryogenesis, the first lineage separation events also give rise to the
first epithelial barriers (Thowfeequ et al., 2022). At the eight-cell stage (embryonic day (E) 2), …

… to explain complex cell behaviours such as motility (see the contributions by Infante and
Etienne-Manneville; Kim et al., in this research topic issue) cell polarisation (ibid Despin-Guitard …
