Foetal stem cells cause tumour.

"A boy treated with foetal stem cells for a rare genetic disease has developed benign tumours, raising questions about the therapy's safety.", so reports BBC's website:

The boy had brain and spinal tunours with suggestions that they came from the foetal stem cells as the tumours where on the same sites as where the injections had been given.

There are safety concerns over the use of experimental stem cells including the possibilities of passing on other diseases or viruses.
