Most animals can regenerate some parts of their bodies, such as skin. But when a three-banded panther worm is
cut into three pieces, each piece grows into a new worm. Researchers are investigating this feat partly to learn
more about humans’ comparatively limited abilities to regenerate, and they’re making exciting progress. An
especially promising discovery is that both humans and panther worms have a gene for early growth response
(EGR) linked to regeneration.

When Mansi Srivastava and her team reported that panther worms, like humans, possess a gene for EGR, it caused
excitement. However, as the team pointed out, the gene likely functions very differently in humans than it does in
panther worms. Srivastava has likened EGR to a switch that activates other genes involved in regeneration in
panther worms, but how this switch operates in humans remains unclear.
