Summary

Story summary

Texas A&M researchers used a two-step protocol—FGF2 after wound closure then BMP2 days later—to regrow bone, tendon, ligament and joint tissue in mice after amputation.
The FGF2 application created a blastema-like structure absent in mammals, which BMP2 then induced reprogrammed fibroblasts to form new skeletal tissues.
Because BMP2 is FDA-approved and FGF2 is in trials, the method could move to human testing quickly.
