Se trata de un innovador paso en la ciencia e investigaci\u00f3n que plantea, sin embargo, dilemas \u00e9ticos y problemas legales.<\/p>\n<p>\u00a0\u00a0\u00a0 \u201cPodemos crear modelos similares a los embriones humanos reprogramando las c\u00e9lulas\u201d, apunta la profesora Magdalena Zernicka-Goetz, del Instituto de Tecnolog\u00eda de California (Estados Unidos) seg\u00fan informaci\u00f3n de The Guardian.<\/p>\n<p>\u00a0\u00a0\u00a0 Estas estructuras no tienen un coraz\u00f3n latiente ni cerebro, aunque incluyen c\u00e9lulas que t\u00edpicamente continuar\u00edan formando la placenta, el saco vitelino y el mismo embri\u00f3n.<\/p>\n<p>\u00a0\u00a0\u00a0 El diario ingl\u00e9s agrega que no existe hasta ahora una perspectiva de que estos embriones sint\u00e9ticos vayan a ser empleados cl\u00ednicamente y que ser\u00eda ilegal implantarlos en el \u00fatero de una paciente. Tampoco est\u00e1 claro todav\u00eda si estas estructuras tienen el potencial de continuar madurando por sobre las fases m\u00e1s tempranas de desarrollo.<\/p>\n<p>\u00a0\u00a0\u00a0 La nota publicada por The Guardian ha causado reacciones en todo el mundo, sin embargo, desde la medicina indican que, para poder hacer un an\u00e1lisis en profundidad, es necesario revisar el art\u00edculo cient\u00edfico completo. Aunque puede ser \u201cun paso cient\u00edfico importante\u201d, es necesario ver \u201cel informe completo y los datos antes de poder hacer esas afirmaciones\u201d, explic\u00f3 Alfonso Mart\u00ednez Arias, de la Universidad Pompeu Fabra, Barcelona, a Science Media Centre, una plataforma que ofrece fuentes cient\u00edficas expertas. En la comunidad cient\u00edfica los estudios se publican en revistas tras la revisi\u00f3n de los textos por otros investigadores independientes para detectar posibles errores.<\/p>\n<p>\u00a0\u00a0\u00a0 Tambi\u00e9n plantean \u201cprofundas cuestiones \u00e9ticas y jur\u00eddicas\u201d y no existe una normativa clara que regule los modelos de embriones humanos derivados de c\u00e9lulas madre, por lo que Briscoe urgi\u00f3 a crear una normativa que establezca un marco para la creaci\u00f3n y el uso de estos modelos de embriones.<\/p>\n<p>\u00a0\u00a0\u00a0 Los modelos obtenidos a partir de c\u00e9lulas madre \u201cpodr\u00edan ofrecer una alternativa \u00e9tica y m\u00e1s f\u00e1cilmente disponible al uso\u201d, a los logrados por fecundaci\u00f3n in vitro. El cient\u00edfico hizo hincapi\u00e9 en que es importante que la investigaci\u00f3n y los investigadores en este campo \u201cprocedan con cautela, cuidado y transparencia\u201d.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n\n\n\n<div
