Specification of germ layer identity in the chick gastrula [PDF]

BMC Developmental Biology, 2007
Abstract Background Chick definitive endoderm is an important source of signals that pattern the early embryo forming a central structure around which the body plan is constructed. Although the origin of definitive endoderm has been mapped in the chick, arising principally from rostral streak at elongating streak stages,

Understanding gene regulation during the development of the sea cucumber Apostichopus japonicus using comparative transcriptomics

Frontiers in Marine Science, 2023
Embryonic development, especially metamorphosis and settlement, has a major impact on the life history of marine invertebrates. Apostichopus japonicus is an economically important species of sea cucumber. In this study, we performed RNA sequencing on six

Preliminary study: the effect of cryopreservation on the gastrula-staged embryo of African catfish (Clarias gariepinus) [PDF]

, 2020
This study was aimed to observe the effect of cryopreservation on gastrula-staged embryo of African catfish. The gastrula-staged embryos were treated 5% (v/v) solutions concentration of dimethyl sulfoxide, propylene glycol, honey, and combined ...

Pre-gastrula expression of zebrafish extraembryonic genes [PDF]

BMC Developmental Biology, 2010
Abstract Background Many species form extraembryonic tissues during embryogenesis, such as the placenta of humans and other viviparous mammals. Extraembryonic tissues have various roles in protecting, nourishing and patterning embryos.

Calcium signaling in tunicate development

Frontiers in Ecology and Evolution
A comparative overview is provided of Ca2+ signaling and its potential mechanistic roles during development in tunicates. As background, the review presents an introduction to tunicate taxonomy, and then a general overview of Ca2+ signaling and methods ...

Nervous System Development and Neuropeptides Characterization in Embryo and Larva: Insights from a Non-Chordate Deuterostome, the Sea Cucumber Apostichopus japonicus

Biology, 2022
Here, we described the complex nervous system at five early developmental stages (blastula, gastrula, auricularia, doliolaria and pentactula) of a holothurian species with highly economic value, Apostichopus japonicus.

HES and Mox genes are expressed during early mesoderm formation in a mollusk with putative ancestral features

Scientific Reports, 2021
The mesoderm is considered the youngest of the three germ layers. Although its morphogenesis has been studied in some metazoans, the molecular components underlying this process remain obscure for numerous phyla including the highly diverse Mollusca ...

Towards gene banking amphibian maternal germ lines: short-term incubation, cryoprotectant tolerance and cryopreservation of embryonic cells of the frog, Limnodynastes peronii.

PLoS ONE, 2013
Gene banking is arguably the best method available to prevent the loss of genetic diversity caused by declines in wild populations, when the causes of decline cannot be halted or reversed.
