Yu and colleagues from Ken Muneoka's group show that sequential FGF2 then BMP2 treatment flips an adult mouse digit amputation from fibrosis to regeneration — rebuilding the distal phalanx with a growth plate, plus a parallel response that regenerates a synovial joint complex with tendon, ligament, and a sesamoid-like bone. The regeneration-competent cells are already in our wound beds. We just have to learn what to say to them.
