The question asked whether a parthenote, which only contained pluripotent and not totipotent cells and was therefore incapable of developing into a human being, was included in the term "human embryo" under Article 6(2)(c) of the Directive.
Taken together our results imply that the frozen storage of PZM3 is feasible and of practical value for culturing parthenote and cloned porcine embryos.
A parthenote is an egg that begins dividing as though it were fertilized even though fertilization has not occurred.
Parthenogenesis (Technique C) would be viewed as an affront to human dignity because: (1) of the need to procure oocytes from a healthy female (generally for a price); (2) of the belief that the whole process is "inhuman" due to its asexual nature; and (3) further manipulation of the parthenote might produce an implantable embryo that could become a human being.
