Stem cells feed brain tumors

Wired: Stem cells feed brain tumors. 

"Researchers have identified stem cells in brain cancer tumors that replenish the tumors and keep them growing.  Snuffing out these cancer stem cells could lead to a raft of new treatments for various cancers.

"Scientists previously identified cancer stem cells in breast cancer tumors, and in leukemia tumors. But no one had found proof of cancer stem cells in other solid tumors until now

Excellent!

And in other stem cell news, FuturePundit report "Sonic hedgehog gene triples brain stem cell growth".  That is "Sonic hedgehog" as in the video game character.  You'll just have to read the article :)
