Another is that the transplanted bits of tumor act nothing like cancers in actual human brains, Fine and colleagues reported in 2006: Real - life glioblastomas grow and spread and resist treatment because they contain what are called tumor stem cells, but tumor stem cells don't grow well in the lab, so they don't get transplanted into those mouse brains.

But that's a risky choice in some cases, because the transplant could reintroduce the cancer with the cells.
