expert comments on new research into stem cells, as published in Nature

A paper published in Nature has shown that different genes are involved in different stages in stem cell development, suggesting that features of adult stem cells cannot be directly inferred from studying stem cells at earlier stages of development. Scientists say the finding illustrates the amount they have yet to learn about stem cell characteristics and development.

Prof Chris Mason, Professor of Regenerative Medicine, University College London, said:

“This paper perfectly illustrates the absolute necessity for research scientists to be actively encouraged to work with all the different cell types that are available. This includes human embryonic, fetal, adult and induced pluripotent stem (iPS) cells. Ultimately, all may be required if we are to achieve the spectrum of safe, effective and affordable cell-based therapies that today’s doctors so desperately need. Whilst the result from the Carnegie Institution is unexpected, the message is clear; the quest for the perfect cell to cure the multitude of serious degenerative diseases is far from over. Just as there is no universal ‘wonder drug’, there is definitely no ‘wonder cell’ in the field of regenerative medicine.”
