However, heritable genome editing of either embryos or gametes poses risks that remain difficult to evaluate. (ethicalresearch.net)

a) Note, again, the reference to only sexual human reproduction - "the moment of conception" - i.e., fertilization. (lifeissues.net)
Thus, while Ramsey agreed that there is a human being present immediately at fertilization, he did not agree that it was also a human embryo or a human person - the classic "pre-embryo" argument. (lifeissues.net)
Whether the new organism is produced by fertilization or by cloning, each new human organism is a distinct entity. (actionlife.org)

Ramsey's statement could thus not apply to the issue of human cloning to begin with. (lifeissues.net)
b) But there is a more fundamental reason why Ramsey's statement might not apply to the issue of human cloning. (lifeissues.net)
But it is perhaps not auspicious to quote him for purposes of the scientific debates on human cloning, because Ramsey agreed with and supported the scientific myth of the "pre-embryo" 47 made famous by Jesuit Richard McCormick and frog embryologist Clifford Grobstein. (lifeissues.net)
Perhaps Ramsey would give other extraordinarily powerful arguments as to why human cloning is unethical, but he obviously would not be able to base it on his unscientific "pre-embryo" position. (lifeissues.net)
a) It would seem that Saunders uses the "potential" argument here quite appropriately, but it is critical that the term be understood properly in order to deflect any misunderstandings or misinterpretations - especially if the term were to be used in any U.

If the term "potential" were to be incorporated into a U. N. treaty on human cloning, it would be necessary to clarify its use as referring to an already existing human being/person. (lifeissues.net)
Again, Saunders is referring to SCNT as "THE" cloning procedure, when there are many other ways to clone a human being as well, and he is scientifically mis-defining the product of SCNT (i.e., the cloned human embryo). (lifeissues.net)

The use of gene-editing technologies in the early stage embryo allows modifications which can be passed on to future generations. (royalsociety.org.nz)

Many politicians, religious leaders, and bioethicists believe that any destruction of the pre-implanted embryo or fertilized egg is akin to murder. (jcpa.org)

This could lead to non-GE treatments that reduce embryo loss in pregnancy and improve fertility. (oxplore.org)

While being caught off guard at the revelation of the gene-edited twins, the medical research community seemed to only condemn the prematurity in the creation of these "designer" babies due to the uncertainty of their safety. (ethicalresearch.net)
One of the main arguments against designer babies is that it could lead to the creation of a society with a narrow definition of what is considered "ideal" or "normal. (vumc.org)
Finally, many argue that designer babies go against the fundamental principles of human dignity and autonomy. (vumc.org)
This disadvantage of genetically engineered babies may be the most significant. (vumc.org)

The subsequent official statement does not address the ethics of human germline editing at all, but only provides suggestions to a "translational pathway to germline editing" in the future. (ethicalresearch.net)
Basic and preclinical research is rapidly advancing the science of somatic and germline genome editing. (ethicalresearch.net)

New gene-editing technologies are enabling a broad range of applications from basic biological research to biotechnology and medicine (see FIG. 2). (royalsociety.org.nz)

and to study allergenic milk protein production in cow embryos cultured in the laboratory (New Zealand). (royalsociety.org.nz)
The embryo is then allowed to mature in the laboratory for a few days before being transferred to a surrogate mum. (geminigenetics.com)

Being important models for the research of embryo development, they have other advantages such as high tolerance to different types of surgical intervention and external breeding. (rwdstco.com)

There are also concerns that the practice could lead to a loss of diversity in the human population, as certain traits may become more prevalent due to selective breeding. (vumc.org)

Every gene in the human body is encoded as deoxyribonucleic acid ("DNA"), and Myriad Genetics confronted the issue of whether a naturally occurring segment of DNA was eligible for patent. (nyu.edu)

Early chimera research was difficult and inexact. (the-scientist.com)

Mouse embryo assay to evaluate polydimethylsiloxane embryo-toxicity. (nc3rs.org.uk)

human beings have developed innovative technologies to treat and cure disease, to enhance human living conditions, and to protect or improve the environment. (jcpa.org)

In 15 years of research I have not been able to get a significant grasp on what genetically engineering humans, fish, soy, corn, milk and other products could mean for humankind. (real-agenda.com)

The text below refers to "Petitioners" (Conestoga) and "Respondents" (the Obama Administration in the form of Secretary of Health and Human Services Kathleen Sebelius and others). (lozierinstitute.org)
The individual can then decide for himself whether or not to take part in this form of screening, and it is still early enough in life to benefit sufficiently. (nature.com)

The human embryo did not begin until after 14-days, thus the above quote from Saunders would not apply. (lifeissues.net)

Considered contrary to the moral law, since (it is in) opposition to the dignity both of human procreation and of the conjugal union. (wikiquote.org)

When they were no longer needed for that purpose, they were donated for research with the informed consent of the donor. (orthodoxwiki.org)
