Vaccine made from stem cells may help prevent colon cancer
Stem cells could potentially be used to vaccinate people against colon cancer. This surprising conclusion was made by researchers from China and the US after laboratory mice immunised with human embryonic stem (ES) cells experienced a dramatic decline in tumour growth compared to control mice. The idea that embryonic material may generate an anti-tumour response is an old one, but one that has never been tested outside animal research, so to find such an effect wit...
