A new research suggests that a person's blood could someday provide replacement cells for that individual's damaged brain or liver.  Human blood contains so-called stem cells that can be transformed outside the body into a variety of cell types. This unexpected, and accident, discovery may add a new element to the politicized debate over whether stem cells that persist in adults can match the therapeutic potential of stem cells derived from human embryos.

I think that this new discovery may be helpful to many people. It may help for people that have a damaged brain or liver get better. If I had damage to my brain or liver I would use this new research to help my damaged brain or liver.
