In vitro actions of platelet rich plasma and resolvin E1 on osteoblast and osteoclast activity
MetadataShow full item record
Platelet-rich plasma (PRP) is a concentrated gel of platelets that contains several growth factors. Growth factors have been recognized as the part of PRP that play role in regeneration of the bone. It is not clear how these growth factors in PRP affect the bone regeneration. Resolvin El (RvEl; 5S,12R,18R-trihydroxyeicosapentaenoic acid) is an pro-resolving lipid mediator derived from omega-3 fatty acid eicosapentaenoic acid and shown to have potent effects on the resolution of inflammation. The purpose of this study was to analyze the action of PRP and RVEl on the proliferation and behavior of osteoblasts and osteoclasts in vitro. PRP was prepared from 14 healthy donors. Osteoblast cultures were from a cell line (Saos2) of osteosarcoma cells. Osteoclasts were differentiated from primary human peripheral blood monocytes. Osteoclastic morphology was studied and activity was analyzed via resorption on dentin discs using SEM. PRP and RVE 1 were added at different doses and time-points. Osteoblast function was analyzed by osteocalcin expression and release. Osteoclast activity was assessed by resorption and cathepsin K expression. PRP and RvEl comparably increased the osteoblastic activity and suppressed the osteoclast differentiation and function. These results suggest that multiple tools are available to reverse the inflammation and restore the lost bone architecture as a result of periodontal disease.
