Bone Repair Biomaterials ScienceDirect
Abstract. Bone tissue has remarkable repair capacity and generally heals by regeneration. This unique potential expressed during remodelling and bone fracture healing is tuned by a complex interplay of active factors and responding cells which resides on an informative extracellular matrix and acts under a strict genetic control and different mechanical stimuli.
