One of the key questions in biology is to identify how tissues are repaired after trauma and understand how stem cells migrate, proliferate, and differentiate to repair tissue damage. Researchers define, for the first time, the changes in the stem cell dynamics that contribute to wound healing.

Scientists reveal that the combination of two molecular signals determines which cells that have already differentiated can regain their stem cell properties.

A new study shows that the act of creating pluripotent stem cells for clinical use is unlikely to pass on cancer-causing mutations to patients.
