The method the team used to create the pups, described in a study1published on 11 October in Cell Stem Cell, reveals important genetic factors necessary for the development of healthy embryos. But scientists are sceptical that the technique could ever be applied to people.

Some animals, such as certain species of birds, fish and lizards, can reproduce using only one sex or an individual. Mammals, however, need members of the opposite sex to create the next generation.
