Targeting cell fusion as possible way to repair organs, deliver cancer vaccines
..., stem cells are used to repair damage in the bone marrow
and to different organs such as the liver, brain and heart. Recent research shows that some of the stem cells' repair properties come from their ability to fuse with cells that are naturally resident in the organs they are repairing. "For example, ...
