Recientemente ha visto la luz en la revista Cell <\/a>un art\u00edculo en el que se describe la capacidad de las c\u00e9lulas madre humanas para formar parte de embriones de mono en cultivos celulares. Este experimento abrir\u00eda as\u00ed la puerta a la creaci\u00f3n de embriones quim\u00e9ricos en los que contribuir\u00edan l\u00edneas celulares procedentes de diferentes especies.<\/p>\n\n\n\n

Estudios previos similares llevados a cabo con cerdos y ratones fracasaron a la hora de generar estas quimeras con c\u00e9lulas humanas. El trabajo actual ha partido de la base de que ser\u00eda necesaria la creaci\u00f3n de quimeras entre especies evolutivamente m\u00e1s pr\u00f3ximas. As\u00ed, en el presente estudio tuvo lugar la creaci\u00f3n de embriones quimera de la especie Macaca fascicularis con contribuci\u00f3n de c\u00e9lulas humanas.<\/p>\n\n\n\n

Pese a los evidentes cuestionamientos \u00e9ticos que surgen de este tipo de experimentos, los autores argumentan que este paso supone un avance necesario a la hora de aprovechar la potencialidad de las c\u00e9lulas madre en la medicina regenerativa. Se pretender\u00eda, pues, con ello establecer la base para la futura generaci\u00f3n de bancos de \u00f3rganos y tejidos \u00fatiles para trasplante en humanos.<\/p>\n\n\n\n
