more: The donor cells often fail to grow or stimulate repair at the injury site, possibly because of the inflammation and scarring present there. The injury site also typically has very limited blood supply and connective tissue, which might prevent donor cells from getting the nutrients they require.

Dr. Zhang's gel, however, can be loaded with different chemicals to stimulate various biological processes at the site of injury. In previous research done on rats, she was able to use the gel to help re-establish full blood supply at the site of brain injury. This could help create a better environment for donor cells.
In a follow-up study, Dr. Zhang loaded the gel with immature stem cells, as well as the chemicals they needed to develop into full-fledged adult brain cells. When rats with severe brain injuries were treated with this mixture for eight weeks, they showed signs of significant recovery.

The new gel could treat patients at varying stages following injury, and is expe

Looks excellent and so a great clip.
Sick sense of humour noticed that the rats had severe brain injuries - did the "collectors" specifically locate such rats, or.......... Maybe "or........

excellent ~~ stem cells hold the secrets of life

You think it would work on the GOP?
