GM Embryos 'Essential', Says Report
It is "essential" that the genetic modification of human embryos is allowed, according to a global group of scientists, ethicists and policy experts. A Hinxton Group report says editing the genetic co...
Beyond Genes: Are Centrioles Carriers Of Biological Information?
Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad r...

Pharyngeal pouch (embryology)
In the embryonic development of vertebrates, pharyngeal pouches form on the endodermal side between the pharyngeal arches. The pharyngeal grooves (or clefts) form the lateral ectodermal surface of the...

Optic cup (embryology)
During embryonic development of the eye, the outer wall of the bulb of the optic vesicles becomes thickened and invaginated, and the bulb is thus converted into a cup, the optic cup (or ophthalmic cup...

Embryotroph is the embryonic nourishment in placental mammals. In order to explain in more depth what an embryotroph actually is, other words such as syncytiotrophoblast and uterine milk must be menti...
Blastocyst
The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM) which subsequently forms the embryo. The outer layer of the blastocyst consists of cells...
