The Development of Transplanted Fragments of Fundulus Gastrulae [PDF]

Proceedings of the National Academy of Sciences, 1953
It was reported by Lutherl some time ago that for the egg of Salmo both embryonic and extra-em'ryonic sectors of the blastoderm accomplished considerable differentiation after transplantation at early gastrula stages to the yolk-sac epithelium of older trout fry.

Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries

Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.
ABSTRACT Nearly 200 years ago, scientists began examining reproductive cells in calcareous sponges (Calcarea, Porifera). Since then, 238 studies have been published, encompassing descriptions of gametes and embryos (including ultrastructural studies), life history, asexual reproduction, regeneration, and molecular aspects of development.

BMP and retinoic acid regulate anterior–posterior patterning of the non-axial mesoderm across the dorsal–ventral axis

Nature Communications, 2016
It is unclear how the dorsal-ventral (DV) and anterior-posterior (AP) axes established in the gastrula affect tissues. Here, the authors show that in zebrafish kidney development, with regard to non-axial mesoderm, the classic DV axis corresponds to the ...

Early and Larval Development of the Marine Species Grey Triggerfish (Balistes capriscus, Gmelin, 1789) and the Use of Different Organisms as First Food Sources

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The aim of this study was to provide an initial description of the embryology and larval development of Balistes capriscus species obtained from natural spawning in captivity. The study also aimed to assess the stocking density and the impact of offering four types of live food as the initial feed during the larviculture phase. Observations of

Isolation of nanobodies against Xenopus embryonic antigens using immune and non-immune phage display libraries.

PLoS ONE, 2019
The use of Xenopus laevis as a model for vertebrate developmental biology is limited by a lack of antibodies specific for embryonic antigens. This study evaluated the use of immune and non-immune phage display libraries for the isolation of single domain

Regulation of Amphibian Gastrulae with Added Ectoderm1 [PDF]

Journal of Experimental Biology, 1938
ABSTRACT If a young Urodele gastrula is cut or constricted into two along the frontal plane, so that the dorsal and ventral halves are separated, the dorsal part contains the whole organization centre but an abnormally small amount of presumptive ectoderm; nevertheless, as Spemann (1903) and Ruud & Spemann (1922) showed, it regulates

Zebrafish Embryos to Profile Nano(bio)materials: A Modular Platform for Developmental Toxicity, Neurotoxicity, and Inflammation‐Regeneration Assays

Current Protocols, Volume 6, Issue 6, June 2026.
Abstract Zebrafish embryos provide a rapid, low‐cost in vivo platform to profile the developmental, neurotoxic, and immunomodulatory effects of engineered nano(bio)materials within a single vertebrate system. This article presents a modular workflow that integrates standardized fish embryo acute toxicity (FET) testing, chemically assisted ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.
