Scientists illuminate a method for safer stem cell treatments

(American Chemical Society) Because they can develop, or differentiate, into basically any tissue type, pluripotent stem cells could be the key to a host of regeneration therapies. But those PSCs in a culture dish that remain undifferentiated could form teratomas, a kind of tumor, if transplanted into patients. This week in ACS Central Science, researchers report a new light-based technology that could remove this risk.
