Stem cells which ‘fool immune system’ may provide vaccination for cancer

Scientists from the United States and China have revealed the potential for human stem cells to provide a vaccination against colon cancer,

The development, led by experts in immunology, Dr. Bei Liu and Dr. Zihai Li, builds upon a century old theory that immunizing with embryonic materials may generate an anti-tumor response. However, this theory has never before been advanced beyond animal research so the discovery that human stem cells are able to immunize against colon cancer is both new and unexpected.

“This finding potentially opens up a new paradigm for cancer vaccine research,” said Dr. Zihai Li. “Cancer and stem cells share many molecular and biological features. By immunizing the host with stem cells, we are able to ‘fool’ the immune system to believe that cancer cells are present and thus to initiate a tumor-combating immune program.”
