I wonder why they didn't do this experiment using monkey stem cells? Good way to test the immune response hypothesis and to see if the stem cells still defend the existing cells or begin to replace them. That said, I still have doubts about stem cell therapies. Since we still don't know what triggers the Pd process isn't adding stem cells a bit like throwing more wood onto a burning barn and then claiming success because the fire takes longer to consume the structure. -- Steve Rack ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn Brattleboro VT
