Embryonic stem cells have a propensity to develop into unusual tumors, referred to as teratomas. Although these tumors tend to be benign, they still represent a major hurdle in the ongoing quest to develop stem cell therapies. Scientists at UC San Diego, however, recently published a study in which they effectively curbed the formation of these tumors.
During their research, the scientists found the critical signaling pathway utilized in the self-propagation of stem cells. By blocking this pathway, scientists were able to reduce the risk of teratoma formation. Hopefully this will lead to a foolproof means of stopping the development of these tumors entirely.
