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. N. treaty on human cloning. (lifeissues.net)
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)

Since embryonic stem cells have the ability to form virtually any cell type in the body, those taken from a cloned embryo could potentially be used to treat many diseases. (nih.gov)
The early mammalian embryo consists of the extra-embryonic cell layers-the trophoblast and a body of cells called the inner cell mass (ICM), which eventually become the embryo proper. (thefutureofthings.com)
The fusion ultimately gives rise to a microscopic embryo, from which embryonic stem cells can theoretically be derived. (the-scientist.com)
In the best case, an early embryo consisting of a few cells may form, but these are not capable of giving rise to human life, nor hESCs for therapeutic purposes. (the-scientist.com)

Before leaving office, President Clinton sought to get around the existing law without actually changing it, by funding research on embryonic stem cells so long as the actual embryo destruction was paid for with private dollars. (eppc.org)
The predominant bioethical concern arising from this technology is that the blastocyt-stage embryo must be destroyed in the process of isolating and separating the embryonic stem cells from the inner mass region of the pre-embryo. (jcpa.org)
The destruction of the pre-embryo has been the critical issue in the U.S. behind imposing limits on federal government-sponsored research in embryonic stem cells. (jcpa.org)

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)
The human embryo did not begin until after 14-days, thus the above quote from Saunders would not apply. (lifeissues.net)
6. " ... any living human embryo has the inherent 'potential' to develop into a healthy baby . (lifeissues.net)
Originally the relevant philosophical term was "potency" (or inherent power or capacity conveyed by a specific nature) was used to apply to an already existing substance - such as a new living human embryo. (lifeissues.net)
In that sense, the human embryo would not be even a human being yet, much less a human person. (lifeissues.net)
Thus if by "potential" one means "potency" - i.e., that the early human embryo already exists with a human nature that is already there, and has its own inherent power or capacity (provided by that human nature) to simply grow bigger and bigger through all the usual developmental stages through birth, then such a statement stands as accurate - both scientifically and philosophically. (lifeissues.net)
That is, it would be acknowledging that the human embryo and the human " baby " are the same human being and human person throughout all of his/her development. (lifeissues.net)
On the other hand, if by "potential" one means that the human embryo is not a human being or human person yet , but might be later once it has been born (i.e., a "baby"), then that statement is both scientifically and philosophically incorrect. (lifeissues.net)

So it is unlikely that the cells would be viable. (wikiquote.org)
Let's say that one in a thousand cells were nevertheless viable, practical issues come into play. (wikiquote.org)

The key is that the DNA, the genetic material in those embryonic stem cells, comes from the patient, whose immune system won't reject the stem cells. (sentientdevelopments.com)

Stem cells are not specialized and the process of their specialization is called differentiation. (benthamscience.com)
The term stem cell can be defined by two very important qualities: the cell has the ability to self-renew and, in a more general sense, the cell has not completed differentiation into its final state. (thefutureofthings.com)
The pheromone signalling pathway of baker's yeast belongs to a class of MAPK (mitogen-activated protein kinase) signalling pathways, which in eukaryotes commonly play a key role in the transmission and translation of extracellular stimuli into intracellular responses such as cell differentiation, proliferation or stress responses.
