Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Conserved Patterns of Cell Movements during Vertebrate Gastrulation [PDF]
, 2005 Vertebrate embryogenesis entails an exquisitely coordinated combination of cell proliferation, fate specification and movement. After induction of the germ layers, the blastula is transformed by gastrulation movements into a multilayered embryo with head,

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

, 2019 A Xenopus (frog) blastula (pre-gastrulation embryo) will undergo predictable movements in gastrulation to form it\u27s three tissue layers, the ectoderm, mesoderm, and endoderm.

Gastrulation: Wnts Signal Constriction [PDF]
, 2006 Recent work shows that Wnt signaling directly regulates the apical constriction that drives gastrulation movements in Caenorhabditis elegans, and also promotes invagination in sea urchins, providing a novel and possibly conserved mode of developmental ...

Secretopathies emerge as a new class of neurocristopathies
Developmental Dynamics, EarlyView.Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

Epigenomic analysis of gastrulation identifies a unique chromatin state for primed pluripotency
Nature Genetics, 2019 Around implantation, the epiblast (Epi) transits from naïve to primed pluripotency, before giving rise to the three germ layers. How chromatin is reconfigured during this developmental window remains poorly understood.

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain
Developmental Dynamics, EarlyView.Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Spinal dysraphism illustrated; Embroyology revisited
Indian Journal of Radiology and Imaging, 2017 Spinal cord development occurs through three consecutive periods of gastrulation, primary nerulation and secondary neurulation. Aberration in these stages causes abnormalities of the spine and spinal cord, collectively referred as spinal dysraphism. They
