nena + nena = nena ?

Parece ser que científicos del Instituto de Genética Reproductiva de Chicago han encontrado una forma de crear "esperma artificial" a partir de células de la médula espinal humana. Tanto para hombres como para mujeres. Lo que hace viable que dos mujeres puedan tener un hijo biológica y genéticamente de ambas. A la vez. Por supuesto (imagino) que la genética nos limitaría a hijas hembras. Os dejo con algunas citas (en particular me gusta la primera) y links interesantes:

• Daily Mail: "A transplant technique has been devised that could effectively remove men from the process of creating life."
• Daily Telegraph: "Women could one day grow their own sperm, says a scientist who today claims to have turned bone marrow into early-stage sperm cells."
• The Independent: "Women might soon be able to produce sperm in a development that could allow lesbian couples to have their own biological daughters, according to a pioneering study published today."
