Does human cloning produce an embryo? In February 1997, Dr. Ian Wilmut and his team surprised the scientific world by demonstrating that the nucleus of an adult sheep's body cell could be used to produce a developing embryo that would grow into another genetically identical sheep. There was no doubt that this process ("somatic cell nuclear transfer") produces an embryo of the species in question. As Dr. Wilmut stated in his groundbreaking article: “Most of the reconstructed embryos were cultured in ligated sheep oviducts… Most of the embryos that developed into morula or blastocyst after 6 days of culture were transferred to the recipients and allowed to develop to term,” etc. [THE. Wilmut et al., “Viable offspring derived from fetal and adult mammalian cells,” 385 Nature 810-813 (27 February 1997)] Now that the discussion has turned to humans, political spokespeople from the biotechnology and pharmaceutical industries have decided to engage in a curious evasion of the fact that somatic cell nuclear transfer using a human nucleus would produce a human embryo. There appear to be two reasons for this: a. some spokespersons argue – contrary to scientific evidence, the findings of the NIH Human Embryo Research Panel, and current federal embryo research law – that no human embryo should be called an “embryo” for the first two weeks of existence.1b. Since cloned embryos are considered useful research material for destructive experiments, current restrictions on embryo research etc. must be evaded by denying that an embryo produced by cloning deserves the name. Hence euphemisms and misleading or imprecise terms ("totipotent cell", "clump of embryonic cells", "unfertilized oocyte", etc.) entered the political discussion. They are used to hide the fact that researchers want to be able to use cloning to produce and destroy human embryos. Biotechnology groups say they oppose the cloning of "human beings" or "people," but reserve the right to conduct cloning experiments on human embryos and fetuses, as long as none are allowed to survive to be born alive. through political evasions by examining professional literature - including the writings of those who advocate cloning embryos for research purposes: "One potential use of this technique would be to take cells - skin cells, for example - from a human patient who had a genetic disease... You take them and bring them back to the beginning of their life by nuclear transfer into an egg to produce a new embryo.
