Such a single - step conversion of an adult cell into an embryonic stem cell entirely avoids the question of
whether an
embryo has been
created, since the cell produced by ANT - OAR never exhibits any of the properties of a single - cell
embryo.
In answer to the question of
whether hybrid
embryos created by CNR might be likely to develop if placed into a woman, the Royal Society notes that it is impossible to answer this question without carrying out an illegal experiment, but that experience to date with other inter-specific hybrid
embryos suggests that development beyond the very earliest stages of gestation would be unlikely.
