Stem cells: let’s draw a line between personal views and scientific fact

I THANK Oliver Broderick (Letters, May 13) for his engaging and questioning letter directed to me on stem cell research.

He wished to know my opinion on ‘induced pluripotency’, or the new method of deriving human pluripotent stem cells. The answer is I am well aware of it and have been engaged in such research for years.

I have published in peer-reviewed journals on the subject (See scienific journals Differentiation and Reproductive Biomedicine Online).
