Molecular anatomy of the pre-primitive-streak chick embryo [PDF]

open access: yesOpen Biology, 2020
The early stages of development of the chick embryo, leading to primitive streak formation (the start of gastrulation), have received renewed attention recently, especially for studies of the mechanisms of large-scale cell movements and those that ...

Cell Polarity and Morphogenesis: Functions and Mechanisms of Cell Divisions in Vertebrate Gastrulation [PDF]

open access: yes, 2004
Gastrulation shapes a vertebrate embryo from an egg-shaped aggregate of cells. In many vertebrates, massive cell divisions occur during gastrulation. In this thesis, I investigate the pattern, function, and regulation of mitotic divisions in zebrafish ...

Characterization of convergent thickening, a major convergence force producing morphogenic movement in amphibians

open access: yeseLife, 2022
The morphogenic process of convergent thickening (CT) was originally described as the mediolateral convergence and radial thickening of the explanted ventral involuting marginal zone (IMZ) of Xenopus gastrulae (Keller and Danilchik, 1988).

Rab7 is required for mesoderm patterning and gastrulation in Xenopus

open access: yesBiology Open, 2021
Early embryogenesis requires tightly controlled temporal and spatial coordination of cellular behavior and signaling. Modulations are achieved at multiple levels, from cellular transcription to tissue-scale behavior.

Quo vadis PGRMC? Grand-Scale Biology in Human Health and Disease

open access: yesFrontiers in Bioscience-Landmark, 2022
The title usage of Latin Quo vadis ‘where are you going’ extends the question Unde venisti from where ‘did you come?’ posed in the accompanying paper and extends consideration of how ancient eukaryotic and eumetazoan functions of progesterone receptor ...

Imaging in Spinal DysraphismA Pictoral Assay [PDF]

open access: yesInternational Journal of Anatomy Radiology and Surgery, 2021
Spinal dysraphism includes the congenital malformations of the spine and spinal cord. Spinal cord development takes place through successive stages of gastrulation, primary neurulation, and secondary neurulation. Defect in any of these three phases can

The cessation of gastrulation [PDF]

open access: yesCell Adhesion & Migration, 2010
An integral component of gastrulation in all organisms is epithelial to mesenchymal transition (EMT), a fundamental morphogenetic event through which epithelial cells transform into mesenchymal cells. The mesenchymal cells that arise from epithelial cells during gastrulation contribute to various tissue rudiments during subsequent development ...

Live imaging of whole mouse embryos during gastrulation : migration analyses of epiblast and mesodermal cells [PDF]

open access: yes, 2013
During gastrulation in the mouse embryo, dynamic cell movements including epiblast invagination and mesodermal layer expansion lead to the establishment of the three-layered body plan.

The major β-catenin/E-cadherin junctional binding site is a primary molecular mechano-transductor of differentiation in vivo

open access: yeseLife, 2018
In vivo, the primary molecular mechanotransductive events mechanically initiating cell differentiation remain unknown. Here we find the molecular stretching of the highly conserved Y654-β-catenin-D665-E-cadherin binding site as mechanically induced by ...

Some Questions and Answers About the Role of Hox Temporal Collinearity in Vertebrate Axial Patterning

open access: yesFrontiers in Cell and Developmental Biology, 2019
The vertebrate anterior-posterior (A-P = craniocaudal) axis is evidently made by a timing mechanism. Evidence has accumulated that tentatively identifies the A-P timer as being or involving Hox temporal collinearity (TC). Here, I focus on the two current
