Complement Proteins C1q-C5 as Context‑Dependent Regulators of Osteoblast Function and Fracture Healing: A Systematic Review.
Background Complement proteins (C1q-C5) participate in immune surveillance and inflammation, but their roles in osteoblast biology and fracture healing remain generally undefined. Emerging evidence suggests that complement activation may exert both pro‑regenerative and pro‑inflammatory effects, depending on receptor en...
