Distinct regulatory mechanisms act to establish and maintain Pax3 expression in the developing neural tube. [PDF]

open access: yesPLoS Genetics, 2013
Pattern formation in developing tissues is driven by the interaction of extrinsic signals with intrinsic transcriptional networks that together establish spatially and temporally restricted profiles of gene expression. How this process is orchestrated at

Diversity in the Development of the Neuromuscular System of Nemertean Larvae (Nemertea, Spiralia)

open access: yesFrontiers in Ecology and Evolution, 2021
In studies on the development of nervous systems and musculature, fluorescent labeling of neuroactive substances and filamentous actin (f-actin) of muscle cells and the subsequent analysis with confocal laser scanning microscopy (CLSM), has led to a ...

Conserved developmental processes and the formation of evolutionary novelties: examples from butterfly wings

open access: yes, 2008
The origin and diversification of evolutionary novelties - lineage-specific traits of new adaptive value - is one of the key issues in evolutionary developmental biology. However, comparative analysis of the genetic and developmental bases of such traits

Embryonic and foetal expression patterns of the ciliopathy gene CEP164.

open access: yesPLoS ONE, 2020
Nephronophthisis-related ciliopathies (NPHP-RC) are a group of inherited genetic disorders that share a defect in the formation, maintenance or functioning of the primary cilium complex, causing progressive cystic kidney disease and other clinical ...

Physiological inputs regulate species-specific anatomy during embryogenesis and regeneration

open access: yesCommunicative & Integrative Biology, 2016
A key problem in evolutionary developmental biology is identifying the sources of instructive information that determine species-specific anatomical pattern.

Cell polarity, cell adhesion, and spermatogenesis: role of cytoskeletons [version 1; referees: 2 approved]

open access: yesF1000Research, 2017
In the rat testis, studies have shown that cell polarity, in particular spermatid polarity, to support spermatogenesis is conferred by the coordinated efforts of the Par-, Crumbs-, and Scribble-based polarity complexes in the seminiferous epithelium ...

Axis Specification in Zebrafish Is Robust to Cell Mixing and Reveals a Regulation of Pattern Formation by Morphogenesis

open access: yesCurrent Biology, 2020
Summary A fundamental question in developmental biology is how the early embryo establishes the spatial coordinate system that is later important for the organization of the embryonic body plan.

Mad is required for wingless signaling in wing development and segment patterning in Drosophila.

open access: yesPLoS ONE, 2009
A key question in developmental biology is how growth factor signals are integrated to generate pattern. In this study we investigated the integration of the Drosophila BMP and Wingless/GSK3 signaling pathways via phosphorylations of the transcription ...

Molecular bioelectricity in developmental biology: New tools and recent discoveries [PDF]

open access: yesBioEssays, 2012
AbstractSignificant progress in the molecular investigation of endogenous bioelectric signals during pattern formation in growing tissues has been enabled by recently developed techniques. Ion flows and voltage gradients produced by ion channels and pumps are key regulators of cell proliferation, migration, and differentiation.

Chick fetal organ spheroids as a model to study development and disease

open access: yesBMC Molecular and Cell Biology, 2021
Background Organ culture models have been used over the past few decades to study development and disease. The in vitro three-dimensional (3D) culture system of organoids is well known, however, these 3D systems are both costly and difficult to culture ...
