Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

Developmental Dynamics, EarlyView.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Spdeadringer, a sea urchin embryo gene required separately in skeletogenic and oral ectoderm gene regulatory networks

, 2003
The Spdeadringer (Spdri) gene encodes an ARID-class transcription factor not previously known in sea urchin embryos. We show that Spdri is a key player in two separate developmental gene regulatory networks (GRNs). Spdri is expressed in a biphasic manner,

Multiple signaling events specify ectoderm and pattern the oral-aboral axis in the sea urchin embryo

, 1997
In the sea urchin embryo, the animal-vegetal axis is established during oogenesis and the oral-aboral axis is specified sometime after fertilization. The mechanisms by which either of these axes are specified and patterned during embryogenesis are poorly

The role of Rho GTPases in facial morphogenesis

Developmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Loss of Twist1 leads to disruption of ciliary length, endocytic vesicle dynamics, and cell–cell junctions during neural tube formation

Developmental Dynamics, EarlyView.
Abstract Background Endocytosis constitutes a fundamental cellular process governing development through coordinated regulation of plasma membrane remodeling and ciliogenesis, processes essential for cell shape changes and tissue development. Although Twist1 null embryos display complete cranial neural tube (NT) closure defects and conditional knockout

The E3 Ubiquitin Ligase GREUL1 Anteriorizes Ectoderm during Xenopus Development

, 2002
We have identified a family of RING finger proteins that are orthologous to Drosophila Goliath (G1, Gol). One of the members, GREUL1 (Goliath Related E3 Ubiquitin Ligase 1), can convert Xenopus ectoderm into XAG-1- and Otx2-expressing cells in the ...

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.

Data on microRNAs and microRNA-targeted mRNAs in Xenopus ectoderm

Data in Brief, 2016
Small RNAs from early neural (i.e., Noggin-expressing, or NOG) and epidermal (expressing a constitutively active BMP4 receptor, CABR) ectoderm in Xenopus laevis were sequenced to identify microRNAs (miRs) expressed in each tissue.

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 ...
