Human Brain Cells Are Grown In Mice - II

Something in this article struck us here at Data Central:

The research offers the first proof that human embryonic stem cells -- vaunted for their potential to turn into every kind of human cell, at least in laboratory dishes -- can become functional human brain cells inside a living animal, reaching out to make connections with surrounding brain cells.

The human cells had no apparent impact on the animals' behavior. About 100,000 cells were injected into each animal and just a fraction survived in their new hosts. That means the animals' brains were still more than 99 percent mouse -- a precaution that helped avoid ethical objections to creating animals that were "too human." (emphasis added)

We are glad that there was no effect on the mice's behavior, becoming human they might have invaded the kitchen looking for WMD and turned our house into a graveyard.

...creating animals that were "too human."

Think about this statement for a minute. Of course, one has to look at it from the mouse's standpoint. Was it ethical for the mouse to have human cells injected into it? I mean, give me a break.

Aye, Carumba!
