The Ability to Regrow Organs Might Be Dormant in Humans

Scientists have been looking at the Hydractinia, a miniature marine animal that has the extraordinary ability to regrow any missing limb — including its head. And while that might sound pretty impressive, what's unique about this creature is that "it retains its embryonic stem cells for life," which can reach any affected area that needs to be reconstructed from scratch.

At a gathering of developmental biologists earlier this year, Frank showed a video of the creature’s head-budding process in action, embryonic stem cells that had been genetically altered to glow green rushing to the neck end of a headless Hydractinia. Attendees were agog. As one tweeted: “Uri Frank shows timelapse movie of Hydractinia stem cells physically moving across to head (wound site) – Wow!”
