In a statement on their website this organisation states:

‘The use of human embryonic stem cells remains an ethically contentious issue due to the potential destruction of the embryo to retrieve the inner cell mass.

In recent years there have been great advances in reverting adult specialised cells back to an undifferentiated state... These cells are known as ‘induced pluripotent stem cells’ or iPSCs and in the future may become as scientifically useful as embryonic stem cells but without the ethical concerns.’

‘Recently we have funded two exciting animal replacement research projects, which feature iPSCs.’
