Summary

Story summary

New studies from the Swiss Federal Institute of Technology Lausanne show oxygen levels and hyaluronic acid significantly influence tissue regeneration in mammals.
The researchers found that low oxygen accelerates wound healing in mouse embryos by activating regeneration programs.
However, higher oxygen levels hinder the regenerative process.
The studies published in Science reveal that mammals have latent regenerative potential and that complete limb regrowth remains unlikely.
