Organism in its earliest stages of development

Usage examples of embryo.

When Agassiz came into the laboratory, I was extracting and preserving the embryos, being interested in embryology.

Even though the embryos from which these cells are derived are developed outside the womb and routinely discarded, antiabortion activists adamantly oppose using them for research no matter how many people stand to benefit.

The embryos were arranged by species: Stegosaurus, Apatosaurus, Hadrosaurus, Tyrannosaurus.

I send you this copy, the first that I have sent to Ayrshire, except some few of the stanzas, which I wrote off in embryo for Gavin Hamilton, under the express provision and request that you will only read it to a few of us, and do not on any account give, or permit to be taken, any copy of the ballad.

But for GalacTech, it meant that human bioengineering experiments could at last be carried out without involving a lot of flaky foster-mothers to carry the implanted embryos.

It turns out that the embryo is endowed with other bipotential structures besides the primordial gonad.

What the black stripes on acetate had delineated with clinical detachment, the photographs in the book revealed with horrifying detail: limbless embryos, Cyclopean fetuses, hydrocephalic stillborn children.

All four embryos were in the so-called blastocyst stage, in which the future child consists of a small cellular cluster at one end of a hollow ball of cells that will eventually form the fetal part of the placenta.

The cloned stem cells in therapeutic cloning are harvested from the blastocyst stage well before any embryo forms.

Save for a few Xican coelenterates that had been stranded on the beach by high tide, the sands were as unblemished as the mind of an embryo, washed pure by an unpolluted sea.

Waalenberg embryos in turn is referenced to stem cell lines that are then tracked to Crocuta crocuta.

In a future chapter I shall attempt to show that the adult differs from its embryo, owing to variations supervening at a not early age, and being inherited at a corresponding age.

If the survivor was a male or a woman too old or otherwise unable to carry a child safely, an embryo could be brought to term in an ectogenetic chamber.

Even so, if Risa waited to make a decision, an emergency might require the use of the cryonic chamber now holding that embryo, and if no ectogenetic chamber was available for it then, the matter would be settled by disposing of the potential child.

Almost every biology book for the past century has included pictures of vertebrate embryos made by German biologist and enthusiastic eugenicist Ernst Haeckel, purportedly demonstrating the amazing similarity of fish, chickens, and humans in the womb.
