Randomized trial examines TGF-β1's role in early bone repair, indicating potential therapies for impaired healing.

This study investigates how macrophage-derived TGF-β1 initiates fracture repair by recruiting osteoprogenitors.
Used murine femoral osteotomy model for fracture healing
Inhibited TGF-β1 signaling with a neutralizing antibody
Depleted macrophages in LysM-iDTR mice using diphtheria toxin administration.
TGF-β1 signaling peaked during the inflammatory phase (p<0.05)
Systemic inhibition of TGF-β1 disrupted MSC recruitment and bone formation (p<0.01)
Local delivery of TGF-β1 improved bone healing in macrophage-deficient mice.

Song et al. (2026) studied this question.
