RNA interference is ineffective as a routine method for gene silencing in chick embryos as monitored by fgf8 silencing. [PDF]

, 2013
The in vivo accessibility of the chick embryo makes it a favoured model system for experimental developmental biology. Although the range of available techniques now extends to miss-expression of genes through in ovo electroporation, it remains difficult

Direct and Latent Effects of Pathogen Exposure Across Native and Invasive Amphibian Life Stages

Frontiers in Veterinary Science, 2021
Emerging infectious diseases are one of the multiple factors contributing to the current “biodiversity crisis”. As part of the worldwide biodiversity crisis, amphibian populations are declining globally.

Disruption of embryonic blood-CSF barrier in chick embryos reveals the actual importance of this barrier to control E-CSF composition and homeostasis in early brain development [PDF]

, 2013
In vertebrates, early brain development takes place at the expanded anterior end of the neural tube. After closure of the anterior neuropore, the brain wall forms a physiologically sealed cavity that encloses embryonic cerebrospinal fluid (E-CSF), a ...

Fluorescence In Situ Hybridization on Early Porcine Embryos [PDF]

, 2010
Insight into the normal and abnormal function of an interphase nucleus can be revealed by using fluorescence in situ hybridization (FISH) to determine chromosome copy number and/or the nuclear position of loci or chromosome territories.

Karyotype characterization, constitutive heterochromatin and nucleolus organizer regions of Paranaita opima (Coleoptera, Chrysomelidae, Alticinae)

Genetics and Molecular Biology, 2006
Species of the subtribe Oedionychina not only have a highly uniform diploid number of 2n = 22 (20+X+y) but have the karyotypic peculiarity of possessing extremely large sex chromosomes.

Equilibrium vitrification of mouse embryos at various developmental stages using low concentrations of cryoprotectants

The Journal of Reproduction and Development, 2021
We previously developed a new vitrification method (equilibrium vitrification) by which two-cell mouse embryos can be vitrified in liquid nitrogen in a highly dehydrated/concentrated state using low concentrations of cryoprotectants. In the present study,

A novel isolator-based system promotes viability of human embryos during laboratory processing [PDF]

, 2012
In vitro fertilisation (IVF) and related technologies are arguably the most challenging of all cell culture applications. The starting material is a single cell from which one aims to produce an embryo capable of establishing a pregnancy eventually ...
