Pitx2c orchestrates embryonic axis extension via mesendodermal cell migration

open access: yeseLife, 2018
Pitx2c, a homeodomain transcription factor, is classically known for its left-right patterning role. However, an early wave of pitx2 expression occurs at the onset of gastrulation in several species, indicating a possible earlier role that remains ...

The Physical Basis of Coordinated Tissue Spreading in Zebrafish Gastrulation

open access: yesDevelopmental Cell, 2017
Summary Embryo morphogenesis relies on highly coordinated movements of different tissues. However, remarkably little is known about how tissues coordinate their movements to shape the embryo. In zebrafish embryogenesis, coordinated tissue movements first

The transcription factor Pitx2 positions the embryonic axis and regulates twinning

open access: yeseLife, 2014
Embryonic polarity of invertebrates, amphibians and fish is specified largely by maternal determinants, which fixes cell fates early in development. In contrast, amniote embryos remain plastic and can form multiple individuals until gastrulation.

Gastrulation dynamics: cells move into focus. [PDF]

open access: yes, 2004
During vertebrate gastrulation, a relatively limited number of blastodermal cells undergoes a stereotypical set of cellular movements that leads to formation of the three germ layers: ectoderm, mesoderm and endoderm.

Optogenetic Control of Nodal Signaling Reveals a Temporal Pattern of Nodal Signaling Regulating Cell Fate Specification during Gastrulation.

open access: yesCell Reports, 2016
During metazoan development, the temporal pattern of morphogen signaling is critical for organizing cell fates in space and time. Yet, tools for temporally controlling morphogen signaling within the embryo are still scarce.

Distinct mesoderm migration phenotypes in extra-embryonic and embryonic regions of the early mouse embryo

open access: yeseLife, 2019
In mouse embryo gastrulation, epiblast cells delaminate at the primitive streak to form mesoderm and definitive endoderm, through an epithelial-mesenchymal transition.

Gastrulation in Birds.

open access: yesJournal of Cell Science, 1912
ABSTRACT In the twentieth volume of the’Journal of Morphology ‘a paper by Mr. J. T. Patterson appeared during the year 1909 under the title, “Gastrulation in the Pigeon’s Egg: A Morphological and Experimental Study,” a preliminary notice of which was published in 1907 in the ‘Biological Bulletin,’vol. xiii.

Ins and outs of Spiralian gastrulation

open access: yesThe International Journal of Developmental Biology, 2014
Gastrulation is a critical stage of metazoan development during which endodermal and mesodermal tissues are internalized, and morphogenesis transforms the early embryo into each animal's unique body-plan. While gastrulation has been studied extensively in classic model systems such as flies, worms, and vertebrates, less is known about gastrulation at a

A system to enrich for primitive streak-derivatives, definitive endoderm and mesoderm, from pluripotent cells in culture [PDF]

open access: yes, 2012
Two lineages of endoderm develop during mammalian embryogenesis, the primitive endoderm in the pre-implantation blastocyst and the definitive endoderm at gastrulation.
