Scientists manage to create a mouse with two male parents: what this advance implies

Using multiple rounds of genetic engineering and cell manipulation, Chinese scientists were able to produce viable “two-parent” mice for the first time. Rodents, who managed to reach adulthood, carry the DNA of two different males of the species, without any contribution from females (with the exception, of course, of the surrogate mothers in which the embryos were gestated).

Os roedores, que conseguiram chegar � vida adulta, carregam o DNA de dois machos diferentes da esp�cie, sem nenhuma contribui��o de f�meas (com exce��o, � claro, das m�es de aluguel em que os embri�es foram gestados).

Creating a mammal, in this case a rat, from two same-sex parents is nothing new. A research team from the Francis Crick Center in London, led by the Japanese Katsuhiko Hayashi, described a procedure in the journal Nature in 2023 to convert male pluripotent cells (embryonic or inducible) into female cells. At the Third International Summit on Human Genetic Editing, Hayashi and his team explained how they were able to convert a male stem cell into…

Criar um mamífero, neste caso um rato, a partir de dois progenitores do mesmo sexo não é novidade, uma equipa de investigação do centro Francis Crick, em Londres, liderada pelo japonês Katsuhiko Hayashi, descreveu um procedimento na revista Nature em 2023 para converter células pluripotentes masculinas (embrionárias ou induzíveis) nas células femininas.   Na Terceira Cimeira Internacional sobre Edição Genética Humana, Hayashi e a sua equipa expl…
