What's up in
As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.
Once again, body cells reveal unexpected plasticity: In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.
With a fully sequenced genome in hand, scientists hope they are finally poised to learn how axolotls regenerate lost body parts.
