Modelos embrionarios con células madre: una reflexión ético-jurídica pendiente
Barra lateral del artículo
Contenido principal del artículo
Resumen
En los últimos años el desarrollo de modelos in vitro con células madre humanas que simulan el desarrollo embrionario temprano ha vivido un gran progreso. Las dificultades para acceder a embriones humanos, la escasez de material embrionario y los desafíos técnicos, legales y éticos existentes sobre la investigación y experimentación con embriones humanos in vitro siguen siendo una barrera para avanzar en el conocimiento de la embriogénesis tras la gastrulación.
El objetivo del presente trabajo de investigación es introducir el estado de la cuestión y analizar la situación ético-jurídica que regula estos modelos de desarrollo. Exponiendo brevemente la situación en territorio español.
La metodología de investigación se ha basado en el análisis de publicaciones científicas, normas jurídicas y principios éticos. La principal conclusión recogida es que los límites de la investigación con embrioides no se han descrito y es probable que se vuelvan indispensables conforme avanza la investigación hacia modelos con potencialidad para ser trasferidos y gestados intraútero.
