The development of the cortex is an elaborate process that integrates a plethora of finely
tuned molecular processes ranging from carefully regulated gradients of transcription …

The epiblast is a single cell-layered epithelium which generates through gastrulation all
tissues in an amniote embryo proper. Specification of the epiblast as a cell lineage in early …

The first lineage choice in mammalian embryogenesis is that between the trophectoderm,
which gives rise to the trophoblast of the placenta, and the inner cell mass, from which is …

Duplex-comb (D) is one of three major loci affecting comb morphology in the domestic
chicken. Here we show that the two Duplex-comb alleles, V-shaped (D* V) and Buttercup …

Male germ cell differentiation is a subtle and complex regulatory process. Currently, its
regulatory mechanism is still not fully understood. In our experiment, we performed the first …

Early cell lineage specification in eutherian mammals results in the formation of a pluripotent
inner cell mass (ICM) and trophoblast. By contrast, marsupials have no ICM. Here, we …

The first day of chick development takes place inside the mother hen (in utero), during which
the embryo progresses from fertilization to late blastula/early gastrula formation. The salient …

The platypus (Ornithorhynchus anatinus) is an egg-laying monotreme mammal whose
ancestors diverged∼ 166 million years ago from the evolutionary pathway that eventually …

During vertebrate development, progenitor cells give rise to tissues and organs through a
complex choreography that commences at gastrulation. A hallmark event of gastrulation is …

T-Box transcription factors are expressed throughout the gestational period and coordinate a
variety of embryonic events that enable proper development, from the first differentiation of …
