(hinxtongroup.org)
To refer to an already existing human embryo, who science has documented for over a hundred years is a new already living human being, as "a child to be" or "future child" is ridiculous on its face, and oddly reminiscent of the draconian government public policies of recent major bioethics British eugenicist and Oxford don R. M. Hare (mentor of Peter Singer). (lifeissues.net)
Believing that early human embryos -- indeed even human newborns and young children -- are just "possible people", Hare's edict for sound public policy would be one that "produces that set of people, of all possible sets of people, which will have in sum the best life, i.e., the best possible set of future possible people.

Somatic-cell nuclear transfer, the technique by which Dolly was created, was first used 40 years ago in research with tadpoles and frogs. (who.int)
The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)
True cloning performed by nuclear transfer from an adult and differentiated somatic cell to a previously enucleated egg (somatic cell nuclear transfer, SCNT), gives rise to a new cell, the nuclovulo (nucleus+ovum), distinct from the zygote because the sperm is not involved in its creation, while both can develop as embryos and give rise to offspring. (sibi.org)
Prior to SCNT, the somatic cell (differentiated) must be reprogramed to a similar state of a pluripotent embryonic cell (undifferentiated) before the nucleus is extracted and transferred. (sibi.org)
In the case of Hua Hua and Zhong Zhong, researchers used modern technology developed only in the last couple of years to enhance the technique used to clone Dolly, which is called somatic cell transfer, or SCNT. (cmaaa.co.za)

However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
In therapeutic cloning on the other hand, genetic material from a body cell is inserted into an egg cell, replacing the nucleus. (boloji.com)

Mammalian genomes are much more complex than yeast genomes, and complete chromosomal rearrangements in mammals have remained unsuccessful," said lead author Li Wei, a researcher with the Institute of Zoology at the Chinese Academy of Sciences in Beijing, for the state-owned Science and Technology Daily . (zmescience.com)
I believe that the reprogramming errors are not the only cause of these low rates of cloning: the mammalian SCNT fails with a very high frequency mainly due to the damage that the technique itself inflicts in the egg and the somatic nucleus, and the very few successful cases occur only when the damage is not significant.

Although this was the ISSCR's first attempt to put that position to the public , it had already made that recommendation to the research community two years previously. (frogheart.ca)

Ecosystem research is important in the work of EMBL scientist Katja Ovchinnikova, who is applying her skills in computer science to study the health of coral reefs. (issuu.com)

If "possible people" like "embryos" means that they can be mutilated and destroyed in destructive experimental research for "the greater good of society", then what's wrong with using adult "possible people" for such purposes too? (lifeissues.net)

Due to the observed ability to conserve genes across generations, the team is confident that their approach could help researchers study how genetics influence conditions like infertility or cancers, and how they could be treated. (zmescience.com)
In many crops, genome engineering techniques have enabled researchers and breeders to take advantage of a vast knowledge base of plant physiology, pathology, and genetics. (frontiersin.org)

Great levels of success and potential have been realized from research using adult stem cells. (wikipedia.org)
