1.   As similar as mouse brains are to human brains, mice are not men.

2.   This indicates that there is something that distinguishes monkey from mouse brains other than the relative sizes of the two species.

3.   Other controls include RNA isolated from tissues of an age-matched non-transgenic mouse brain RNA designated nTgB.

4.   And, responding to some precise but unknown signal, they spawned the exact kind of cell the mouse brains lacked and repaired the nerve damage.

5.   For example, the antibody against Ab made by Elan Pharmaceuticals near San Francisco makes plaques in mouse brains vanish.

6.   Researchers can already do amazing things with mouse brains.

7.   The mice brains were examined later and the researchers found Y chromosome cells incorporated into several brain structures.
