Abstract
"El pasado 7 de junio la revista Nature reconoce imposibilidad de obtener células troncales para investigación, mediante el inefi ciente proceso de transferencia del núcleo de una célula de adulto a oocitos humanos. Al mismo tiempo acepta que ese tipo celular, tan buscado y sometido a fraude, se ha obtenido limpiamente por el procedimiento contrario; esto es, reprogramando hacia atrás, mediante ingeniería genética, una célula de adulto. Se estrena para el caso nueva revista Cell Stem Cell y Nature Reports Stem Cells, publica online una serie de comentarios con los que se intenta mantener el término clonación para lo que es una fecundación convencional. Y es que es embrión humano, resultante de tal fecundación in vitro, será de nuevo el material de partida de otros intentos, inútiles e innecesarios, en el empeño por mantener viva la investigación consumidora de embriones humanos. La investigación biomédica, ética y racional, sigue su curso alejada de los intereses ideológicos y políticos que la empañarían" ["Nature has recently accepted (June 7th, 2007) the impossibility to obtain stem cells through nuclear transference to human eggs. They state also that this type of cell, so often looked for and subjected to fraud, has been achieved reprogramming backwards through genetic engineering an adult cell. A new journal, Cell Stem Cell, has just appeared publishing this achievement. And Nature Reports Stem Cells publishes online a series of comments pretending to preserve the term cloning to indicate for something, which is really a conventional fertilization. The human embryo from such in vitro fertilization will be again the starting material of useless and unneeded attempts to keep alive a research. on human embryos. Biomedical research, faithful to ethical and rational principles, keeps working on paths removed from illegitimate ideological and political interests"]
