Every day, the human body replaces an estimated 10 billion cells lost to injury or ordinary cellular housekeeping. More dramatically, cut a worm into two fragments and each fragment regenerates a complete organism. Cut it into eight fragments and each individual fragment will go on to regenerate a complete animal. How does this regeneration occur?
Dr. Alejandro Sánchez Alvarado discusses the system he and his team developed to study animal regeneration. He explains how his research is shedding light on the way adult animals replace body parts lost to injury and how this has an impact on human health.
