Human breasts grown on mice
Nature Science Update, Mar. 23, 2004
Lab mice have grown human breast tissue on mice. Researchers commonly use genetically engineered mice to study cancer, but the animal disease differs slightly from the human one. Transplanting human breast tissue into mice will make a better model.
So I'm wondering is how these lab mice started doing experiments on mice... but more importantly, why?! Maybe it has something to do with immitating the human caste system.
I think we should sick some PETA people on those lab mice.
