(From Canada.com). A Canadian doctor has confirmed that adult stem cells can be used to regenerate muscle tissue. In a sign of the times, much of the article is taken up with the doctor's desire to avoid having his work politicized: "I want to make sure I am cautious enough so this research will not be used for political reasons." "Nobody should exploit it to say we should stop studying embryonic stem cells." Politicians should stop interfering with medical research - they are slowing progress and damaging our future health and longevity.
