Summary

The decision last week by the biotech company Geron to cancel the first-ever clinical trial using human embryonic stem cells (hESCs) and sell off its stem cell programs has shaken the biomedical research community. Some worry that Geron's announcement, which the company attributes to financial concerns, will dampen enthusiasm from other companies and the public for hESC research. But others see the half-completed trial as smoothing the way for future human studies.
