Scientists Make Progress Toward Limb Regeneration With Serum That Triggered Digit Regrowth in Mice

Summary

Scientists are researching limb regeneration in mammals, inspired by salamanders like axolotls that can regrow lost limbs in 40-50 days. A recent breakthrough involved a serum that helped mice regrow part of a digit by triggering blastema formation, suggesting a potential future pathway toward human limb regeneration. While still early-stage research, this could eventually lead to medical treatments where humans regrow fingers or limbs instead of relying on prosthetics.
