A new study reveals the key lies not in the production of a regrowth molecule, but in that molecule's controlled destruction. The discovery could inspire future regenerative medicine.

"In a study published in Nature Communications, the researchers reveal an elegant molecular mechanism that acts like a GPS coordinate system for regenerating cells… the puzzle was how the cells in the regenerating limb-stump controlled their levels so precisely to know exactly where they were on the axis from shoulder to hand.”
