Mammals May Have a Hidden Limb Regeneration Ability We Never Knew About

Texas A&M researchers induced partial toe regeneration in mice using two proteins, FGF2 and BMP2.

The treatment shifted healing away from scar formation and toward a blastema-like regenerative response.

The mice regrew bones and connective tissues, though the new digits were not fully normal.

The study suggests mammal tissue may be coaxed into regrowth, with possible future uses in wound healing and regenerative medicine.
