Some analysts are quick to note that President Obama has not yet lifted the Bush Administration bans on most stem cell research. But stock touts are now bullish on the sector.
Geron's work was actually ready for trial in 2005, and CEO Thomas Okarma has stated in a video that a lot of efforts have been stopped over the years. But that's only in the U.S. -- many patents have already been issued for use of stem cells in East Asia.
The actual impact of the therapy on the body is unknown. Its goal is to have the body produce myelin, the "insulation" around nerves that allows them to become useful. But all the company has said that in rats it worked better than a placebo.
So advocates still have hurdles to cross. Are approvals of stem cells now just benefitting our global competitors? Will President Obama formally change course? And do these therapies work?
