Sentences with phrase «vertebrate embryos»

LMU researchers have shown that patterns of activity of certain genes in vertebrate embryos correlate with differences in the length of the neck region.

Bone morphogenetic protein 2 signaling negatively modulates lymphatic development in vertebrate embryos

An elaborately orchestrated genetic program transforms generic neural cells in vertebrate embryos into motor neurons that control specific muscular movements.

Fitch and co-authors Richard Wrangham of Harvard University and Adam Wilkins of Humboldt University in Berlin, who proposed their theory in July in Genetics, point out that these traits are controlled by so - called neural crest cells, which in vertebrate embryos form a neural tube along the spine.

Generations of biology students have been convinced — in part because of drawings done 123 years ago by the German biologist Ernst Haeckel — that vertebrate embryos of different animals pass through an identical stage of development.

The wandering cells are neural crest cells, which appear early in development in vertebrate embryos.

13 In vertebrate embryos, neural crest cells (NCCs) form along the dorsal side, or crest, of the neural tube (the proto - central nervous system).

Human embryos — all vertebrate embryos — have pharyngeal arches.

The result was the discovery of three new mammalian genes - known as sonic, Indian, and desert hedgehog - and the realization that the proteins they coded accounted for a significant proportion of all developmental interactions known to occur in the vertebrate embryo.

Not exact matches

In the treated chick embryos, the palate looked more like it does in other vertebrates: flat and seemingly reconnected to the jaw bones.

Finding fossilized eggs containing 3 - D embryos opens a new window into pterosaur development, says coauthor Alexander Kellner, a vertebrate paleontologist at Museu Nacional / Universidade Federal do Rio de Janeiro.

Zebrafish have emerged as an important vertebrate model for cardiovascular research for a number of reasons, including the ability to regenerate its heart if damaged, and because the transparency of the embryos allows easy observation of internal processes like blood vessel development.

A new study reveals that this process may have evolved long ago, as it shows that embryos from an ancient spider develop just like those of vertebrate animals.

The work is the first to show how manta ray embryos get oxygen, says John Musick, a vertebrate ecologist at the Virginia Institute of Marine Science in Gloucester Point.

Schoppmeier and his colleagues are now trying to determine whether Notch and related genes turn on and off in the same fashion in early spider embryos as they do in vertebrates.

But Bronner and her team noticed that while mature lamprey have gut neurons like other vertebrates, lamprey embryos lack these vagal cells.

The zebrafish is a good choice because of its similarity to humans as a vertebrate, its transparency as an embryo, and the powerful genetic tools available in this model organism.

The reasons for its appeal are many, but none rival the fact that the crystal - clear zebrafish embryo offers a view of burgeoning life that no other vertebrate model can.

Visceral left - right asymmetry occurs in all vertebrates, but the inversion of embryo turning (inv) mouse, which resulted following a random transgene insertion, is the only model in which these asymmetries are consistently reversed.
