Los autores estudiaron células madre derivadas de óvulos no fertilizados de hembras de simio. Tras más de dos años de crecimiento y desarrollo, los investigadores escriben que estas células parecen y actúan como las derivadas de embriones. Además, tratadas con las sustancias químicas adecuadas, estas células fueron capaces de desarrollarse como muchos tipos de células especializadas, desde células cardíacas a nerviosas.

Óvulos no fertilizados pueden ser una fuente de células madre
Un trabajo publicado en "Proceedings of the National Academy of Sciences" por investigadores de la Universidad de Wake Forest (Estados Unidos) indica que óvulos no fertilizados pueden representar una útil fuente de células madre y que dicha fuente evitaría los problemas éticos asociados al uso de embriones para la obtención de tales células.
