Virtual cells in a virtual microenvironment recapitulate early development-like patterns in human pluripotent stem cell colonies

open access: yesStem Cell Reports, 2023
Summary: The mechanism by which morphogenetic signals engage the regulatory networks responsible for early embryonic tissue patterning is incompletely understood.

A hypomorphic mutation in Pold1 disrupts the coordination of embryo size expansion and morphogenesis during gastrulation

open access: yesBiology Open, 2022
Formation of a properly sized and patterned embryo during gastrulation requires a well-coordinated interplay between cell proliferation, lineage specification and tissue morphogenesis.

Rho1 activation recapitulates early gastrulation events in the ventral, but not dorsal, epithelium of Drosophila embryos

open access: yeseLife, 2020
Ventral furrow formation, the first step in Drosophila gastrulation, is a well-studied example of tissue morphogenesis. Rho1 is highly active in a subset of ventral cells and is required for this morphogenetic event.

Stat3/Cdc25a-dependent cell proliferation promotes embryonic axis extension during zebrafish gastrulation [PDF]

open access: yes, 2017
Cell proliferation has generally been considered dispensable for anteroposterior extension of embryonic axis during vertebrate gastrulation. Signal transducer and activator of transcription 3 (Stat3), a conserved controller of cell proliferation ...

Notch-dependent and -independent transcription are modulated by tissue movements at gastrulation

open access: yeseLife, 2022
Cells sense and integrate external information from diverse sources that include mechanical cues. Shaping of tissues during development may thus require coordination between mechanical forces from morphogenesis and cell-cell signalling to confer ...

Random migration of induced pluripotent stem cell-derived human gastrulation-stage mesendoderm. [PDF]

open access: yesPLoS ONE, 2018
Gastrulation is the initial systematic deformation of the embryo to form germ layers, which is characterized by the placement of appropriate cells in their destined locations.

The Adaptor Protein Lurap1 Is Required for Cell Cohesion during Epiboly Movement in Zebrafish

open access: yesBiology, 2021
Cell adhesion and polarized cellular behaviors play critical roles in a wide variety of morphogenetic events. In the zebrafish embryo, epiboly represents an important process of epithelial morphogenesis that involves differential cell adhesion and ...

A zebrafish embryo screen utilizing gastrulation identifies the HTR2C inhibitor pizotifen as a suppressor of EMT-mediated metastasis

open access: yeseLife, 2021
Metastasis is responsible for approximately 90% of cancer-associated mortality but few models exist that allow for rapid and effective screening of anti-metastasis drugs.

Regional requirements for Dishevelled signaling during Xenopus gastrulation: separable effects on blastopore closure, mesendoderm internalization and archenteron formation [PDF]

open access: yes, 2004
During amphibian gastrulation, the embryo is transformed by the combined actions of several different tissues. Paradoxically, many of these morphogenetic processes can occur autonomously in tissue explants, yet the tissues in intact embryos must interact

Ptenb mediates gastrulation cell movements via Cdc42/AKT1 in zebrafish.

open access: yesPLoS ONE, 2011
Phosphatidylinositol 3-kinase (PI3 kinase) mediates gastrulation cell migration in zebrafish via its regulation of PIP(2)/PIP(3) balance. Although PI3 kinase counter enzyme PTEN has also been reported to be essential for gastrulation, its role in ...
