Embryo in sentence

86 examples of Embryo in a sentence

Common convention is to transfer the embryo three days after fertilization, when the embryo has eight cells, or on day five, when the embryo is called a blastocyst, and has hundreds of cells.
Should an embryo cell become a blood cell?
The decision between orange and black happens early on in the womb, so that orange-and-black patchy pattern, it's an exact readout of what happened when that cat was just a tiny little kitten embryo inside her mom's womb.
Audience: I was told that many of the brain cells we have as adults are actually in the human embryo, and that the brain cells last 80 years or so.
Its half-shelled body illustrates an important point about the modern turtle: it actually has two shells that develop totally separately while the turtle is still an embryo.
But there are more important things that are already occurring: embryo screening.
You take a six to eight cell embryo, you tease out one of the cells, you run a genetic test on that cell, and depending on the results of that test you either implant that embryo or you discard it.
Today, we know human embryos have tails that dissolve as the embryo develops.
If they were, why would an embryo implant in a toxic swill?
Because with estrus, the final signaling to get the lining of the uterus ready actually comes from the embryo.
So over the millennia that we have evolved, it's been a little bit like an arms race in the uterus, the lining getting thicker and thicker and thicker, and the embryo getting more invasive until we reach this détente with the lining of the uterus that we have.
The plot revolved around an astronaut that came back to earth with alien embryo's inside of him.
Don't worry; I'm not just stumbling over details or being exaggeratedly bitter, as there are several more reasons to state why "Embryo" is a huge failure.
The only two major changes in almost twenty years were the addition of ridges on their heads in "Aliens" and the eggs being able to squirm in "Alien Ressurrection" Every other Aliens has the time between Alien embryo going in and chestburster coming out to be a day or so.
But on December 18, 2014, the ECJ reversed its 2011 ruling, determining that an unfertilized human ovum stimulated by parthenogenesis “does not constitute a human embryo, if it does not in itself have the inherent capacity of developing into a human being.”
There are also pending patent applications for a novel form of genetic manipulation – CRISPR/Cas9-mediated gene editing – which a team of Chinese researchers has already attempted to use to edit the genome of a human embryo.
Notably, under the ECJ’s “inherent capacity” definition, the embryos used in that experiment would not constitute a human embryo, and thus would not be excluded from patentability.
Baroness Mary Warnock, the moral philosopher who chaired the British government committee responsible for the 1984 “Warnock Report,” which established the framework for her country’s pioneering legislation on in vitro fertilization and embryo research, disagrees.
Instead, one could perform pre-implantation genetic diagnosis to identify a normal embryo (the parents’ eggs and sperm would produce both affected and unaffected embryos), and then implant it in the uterus.
Britain’s Dangerous Lapse in Medical EthicsLONDON – On July 17, the United Kingdom’s influential Nuffield Council on Bioethics implicitly endorsed “heritable genome editing,” declaring the practice of altering the DNA of a human embryo “morally permissible” under certain circumstances.
Hwang and his colleagues claimed to have replaced the nucleus of an unfertilized human egg with the nucleus of an ordinary cell taken from another person, developing stem-cell lines from the resulting embryo that matched the DNA of the person who supplied the ordinary cell.
If it is the uniqueness of human embryos that makes it wrong to destroy them, then there is no compelling reason not to take one cell from an embryo and destroy the remainder of it to obtain stem cells, for the embryo’s “unique genetic potential” would be preserved.
If the test is positive, the pregnancy can be terminated, or, in the case of pre-implantation diagnosis, the embryo will be discarded.
When we have a choice between lives with such different prospects – and can make the choice before the embryo or fetus has any awareness at all – shouldn’t we be able to choose the child with the better prospects?
Perhaps inevitably, our access to human eggs and embryos now enables us to extend prenatal genetic diagnosis to the pre-implantation embryo.
Because the diagnosis is made prior to placement of the embryo in the woman's uterus, the exclusion of specific abnormalities is possible without terminating an established, ongoing pregnancy.
In this case, an embryo is being selected not only to avoid congenital disease and thus directly benefit the resulting child, but also to produce a child whose very existence could provide a cure for an older sibling, and with virtually no risk to the donor child.
The extension of prenatal diagnosis to an embryo in a laboratory dish will, in turn, reduce the incidence of certain types of genetically transmitted diseases.
A stem cell can come from an embryo, fetus or adult.
Such evidence fuels the moral debates about embryo research.
