The Combined Potential of PRP and Osteoinductive Carrier Matrices for Bone Regeneration.

In regenerative medicine, orthobiologics, particularly platelet-rich plasma (PRP), are widely used due to their ability to enhance natural tissue repair mechanisms. PRP contains a concentrated pool of growth factors and cytokines that enhance regeneration while also acting as a biomimetic scaffold, thereby optimizing the microenvironment for tissue healing. In bone tissue engineering, PRP is commonly combined with synthetic or natural biomaterials, as its fibrin matrix alone lacks sufficient mechanical stability. However, even such composite systems frequently exhibit limited osteoinductive capacity, necessitating further supplementation with bioactive components. This review evaluates the regenerative potential of PRP in bone defect healing when combined with osteoinductive agents in preclinical in vivo models. We present compelling experimental evidence supporting the efficacy of this combined therapeutic approach.
