Los científicos británicos fueron los primeros en el país que tuvieron licencia para llevar a cabo la clonación terapéutica. Aunque la investigación británica está por detrás de la surcoreana, los científicos de Newcastle están tratando de conseguir tratamientos para poder combatir enfermedades como el Parkinson o el Alzheimer.
El Prof. Chris Higgins, del Consejo Médico de Reino Unido indicó que "esto supone un gran avance porque ofrece la posibilidad de terapias que no tengan rechazo". Por su parte, el Prof. Ian Wilmut, del Roslin Institute de Edimburgo y creador de la oveja Dolly, consideró que "estas observaciones son un paso muy significativo e importante hacia el uso de células de embriones humanos clonados para investigación y terapia".
Roger Pedersen, profesor de medicina regenerativa de la Universidad de Cambridge, explicó que el trabajo supone una "extensa prueba" de la posibilidad de reemplazar el genoma de un óvulo humano con el de una célula del cuerpo de un adulto.
No obstante, los grupos pro-vida como ProLife Alliance mostraron su malestar por el avance. Su portavoz, Julia Millington, indicó que esta clonación no es ética. Aunque se pueden clonar embriones con fines terapéuticos en Reino Unido, clonar con fines de reproducción humana está prohibido desde el año 2001.
