(15) Artificial parthenogenesis
(Technique C) and the creation of iPS cells (Technique D) are too new to have generated much debate, but assumedly would be less controversial because they avoid destroying an embryo that might develop into a human being.
Previous papers have reported that artificial parthenogenesis
in sea stars can be induced--for example, by treatment with thymol or methylxanthine (Obata and Nemoto, 1984; Washitani-Nemoto et al., 1994).
In addition, Pauly's account of Loeb's invention of artificial parthenogenesis
is particularly interesting as a counterpart to the historical accounts of the controversy over recombinant DNA in the 1970s.
