[quote=Markus]There is one thing that nags me, people with cancer have received blood transfusions. According to the above some of them should have benefitted from this (unless you need fresh cells)?

According to the article they find mice with immune systems that have strong cancer fighting properties. Up until now the human transfusions you speak of have not been done with this consideration in mind. You really should read the article.

However as you say these are "mice" and not humans.
