Excerpt:

Scientists have successfully transplanted stem cells from donors into patients who suffered heart attacks and reduced their heart damage. The new research suggests stem cells donated by strangers proved as safe and effective as patients' own cells for helping restore heart tissue. The study, published in the Nov. 5 issue of the Journal of the American Medical Association, involved only 30 patients in Miami and Baltimore, but it proves the concept that anyone's cells can be used to treat such cases. Doctors are excited because this suggests that stem cells could be banked for off-the-shelf use after heart attacks, just as blood is kept on hand now. Skin cells transformed into beating heart tissue, fueling heart failure treatment hopes Stem cells heal heart attack scars, regrow healthy muscle Stem cells cure heart failure?

"Even in patients who had heart attacks several decades before treatment, both donor and recipient stem cells reduced the amount of scarring substantially, by one-third."

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
