From the San Diego Union-Tribune, 5/16/2013:

High-quality scientific research is hard work. There are moments of serendipity, to be sure, but even the most inspired ideas demand scrupulous validation. Nowhere is that more true than in the health sciences and medicine where our well-being and lives are literally at stake.

As stem cell scientists seeking new ways to treat many terrible diseases, we must take great care to ensure the therapies we develop are based upon sound scientific research, and proven to lack undesirable or life-threatening complications.

Yet as we write, the Italian Parliament is considering legalization of an unproven, untested and largely unexplained stem cell treatment. Good science and lives are at risk, with potential implications and consequences for vulnerable patients and families in San Diego.
