Publican sus experimentos en la edición electrónica de "Science", donde además muestran que esos óvulos pueden ser incluso estimulados para desarrollarse en estructuras embrionarias blastocistos- sin la acción de espermatozoides.
Si puede conseguirse lo mismo con células madre humanas, esta investigación podría tener importantes repercusiones en el campo de la clonación terapéutica, en el de la reproducción asistida y en otros ámbitos, escriben los autores. Por ejemplo, explican que en experimentos de clonación terapéutica los científicos podrían generar un suministro de óvulos para investigar sin tener que recurrir a donantes.
