Differential impact of TGF beta/SMAD signaling activity elicited by Activin A and Nodal on endoderm differentiation of epiblast stem cells

Allocation of cells to an endodermal fate in the gastrulating embryo is driven by Nodal signaling and consequent activation of TGF beta pathway. In vitro methodologies striving to recapitulate the process of endoderm differentiation, however, use TGF beta ...

Anatomically and functionally distinct thalamocortical inputs to primary and secondary mouse whisker somatosensory cortices

Carl Petersen, Georgios Foustoukos, Sami El-Boustani, Berat Semihcan Sermet

Subdivisions of mouse whisker somatosensory thalamus project to cortex in a region-specific and layer-specific manner. However, a clear anatomical dissection of these pathways and their functional properties during whisker sensation is lacking. Here, we us ...

What are you synching about? Emerging complexity of Notch signaling in the segmentation clock

Andrew Charles Oates, Olivier François Venzin

The Segmentation clock is a population of cellular genetic oscillators, located in the posterior of the elongating vertebrate embryo, that governs the rhythmic and sequential segmentation of the body axis into somites. Somites are blocks of cells that give ...

Cardiovascular morphometry with high-resolution 3D magnetic resonance: First application to left ventricle diastolic dysfunction

Nikolaos Stergiopoulos, Orestis Vardoulis, Davide Piccini

In this study, an image-based morphometry toolset quantifying geometric descriptors of the left ventricle, aorta and their coupling is applied to investigate whether morphological information can differentiate between subjects affected by diastolic dysfunc ...

From the early steps of whisker formation to its evolutionary disappearance: the (curious) case of Prdm1 and its regulation

Pierluigi Giuseppe Manti

Whiskers (also known as vibrissae) are sensory organs that are thought to have first appeared in Therapsida, a group of synapsids that includes mammals and evolutionary ancestors like the Thrinaxodon(1). They are highly conserved among mammals to the notab ...

3D Assessment of Mandibular Growth Based on Image Registration: A Feasibility Study in a Rabbit Model

Background. Our knowledge of mandibular growth mostly derives from cephalometric radiography, which has inherent limitations due to the two-dimensional (2D) nature of measurement. Objective. To assess 3D morphological changes occurring during growth in a r ...

Zebrafish hmx1 promotes retinogenesis

Ocular development is controlled by a complex network of transcription factors, cell cycle regulators, and diffusible signaling molecules. Together, these molecules regulate cell proliferation, apoptosis and specify retinal fate. In the zebrafish (Danio re ...

Microenvironmental reprogramming of thymic epithelial cells to skin multipotent stem cells

Yann Barrandon, Stéphanie Claudinot, Alessandro Wataru Amici, Paola Bonfanti

The thymus develops from the third pharyngeal pouch of the anterior gut and provides the necessary environment for thymopoiesis (the process by which thymocytes differentiate into mature T lymphocytes) and the establishment and maintenance of self-toleranc ...

Rostral and caudal pharyngeal arches share a common neural crest ground pattern

Denis Duboule

In vertebrates, face and throat structures, such as jaw, hyoid and thyroid cartilages develop from a rostrocaudal metameric series of pharyngeal arches, colonized by cranial neural crest cells (NCCs). Colinear Hox gene expression patterns underlie arch spe ...

Retinoic acid signaling organizes endodermal organ specification along the entire antero-posterior axis

Anne Grapin-Botton

BACKGROUND: Endoderm organ primordia become specified between gastrulation and gut tube folding in Amniotes. Although the requirement for RA signaling for the development of a few individual endoderm organs has been established a systematic assessment of i ...
