cloned embryos created.

unused embryos created during in vitro fertilization, but that process destroys the blastocyst.)
The respondents were also divided on
whether embryos created for IVF should be made available for use in research if they are unwanted by their parents.
Although he never banned this research outright, President Bush limited federal funding for research to the embryonic stem cell lines that existed before August 2001, thus drawing a line at destroying human
embryos created after that date.

early embryos created by somatic - cell nuclear transfer and implanted into various ewes by Roslin researchers, only one, Dolly, survived, suggesting that the technique currently has a high rate of embryonic and fetal loss.
In answer to the question of whether
hybrid embryos created by CNR might be likely to develop if placed into a woman, the Royal Society notes that it is impossible to answer this question without carrying out an illegal experiment, but that experience to date with other inter-specific hybrid embryos suggests that development beyond the very earliest stages of gestation would be unlikely.
This legislation requires that spouses or common - law partners provide joint consent to use or donate in
vitro embryos created for their reproductive use, and also allows one spouse or partner to unilaterally withdraw his or her previously given consent, in writing, prior to the embryos being used, thawed or designated for a specific purpose.
Today, doctors working with
embryos created through in vitro fertilization can extract a few cells for genetic testing in a process called preimplantation genetic diagnosis, or PGD.
Currently, gamete donors sign a form giving the IVF patient legal authority to determine the use of
embryos created with their gametes after infertility treatment has been completed.
Stem cell researchers call them «a major step in the right direction,» although some were disappointed that NIH didn't open the door to the use
of embryos created for research purposes — including through somatic cell nuclear transfer (cloning) and parthenogenesis (from an unfertilized egg).
The Swiss government has agreed that
embryos created via in vitro fertilisation (IVF) can, under strict conditions, be screened for...
It would allow funding on lines
using embryos created for in vitro fertilization and slated for disposal.
Proponents of ESC research counter that most of the new cell lines could be derived from donated, unused
human embryos created by couples seeking fertility treatment, and that more than a third of zygotes fail to implant after conception, so those would be lost by chance anyway.
Research on a new «gene editing» technology known as CRISPR — which theoretically allows any cell or organism to have its genome altered — is advancing exponentially, with early research ongoing on human
embryos created for that purpose.
After months of discussion, the group drafted a call to ban all human cloning and to limit ESCR to the use of the «excess»
embryos created in the process of in vitro fertilization (IVF).
After a successful IVF procedure in 2007 brought us our daughter in 2008, we tried again so that we could fulfill our commitment to give
every embryo we created a chance at life.
This is an arrangement that involves the transfer of
an embryo created through in vitro fertilization using an egg from a donor or an intended mother and sperm from an intended father or a sperm donor.
We then transfer
an embryo created by each partner to the gestational carrier.
Embryos created through somatic cell nuclear transfer, which uses skin cells taken from the sick child, could also be used to test therapies.
The embryo created by the research - through which human DNA is injected into a hollowed - out animal egg - is 99.9 percent human and 0.1 percent animal.
This bill (S. 1602) outlaws the implantation of human
embryos created by nuclear transfer technology, not the technology itself.
The problem, Yang says as she leaps to the front of the conference room, is that removing the DNA - containing nuclei from pig ova isn't always complete; occasionally some of an ovum's own PERV - infested genes remain behind, so
the embryo created from it also has PERVs, genetic analyses showed.
There should be a complete ban on the implantation of a human
embryo created by the application of cloning technology into a womb, or any treatment of such a human embryo intended to result in its development into a viable infant.
(
An embryo created this way will not develop into a fetus.)
The study analysed fertility outcomes such as number of eggs retrieved, number fertilised, number of
embryos created, implantation rate and live birth rate, which was the main outcome measure in the study.

embryos created for in vitro fertilization.
