The embryo-sac of Euphorbia heterophylla L.- a reinvestigation

open access: yes, 1942
A reinvestigation of the embryo-sac of Euphorbia heterophylla shows that the development is not of the Adoxa- type as reported by Sanchez (1938) but of the Normal- type. The megaspore-mother cell gives rise to a tetrad of megaspores of which the chalazal

Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Role of SoxE transcription factors in development and disease

open access: yesDevelopmental 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.

Embryonic development of the Mediterranean starfish Hacelia attenuata

open access: yesDevelopmental 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 ...

Secretopathies emerge as a new class of neurocristopathies

open access: yesDevelopmental 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.

MIT/TFE family transcription factors, Mitf and Tfec, redundantly promote pigment cell differentiation and retinal epithelium pigmentation in teleosts

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...
