Comparative analysis of local stimulation methods of reparative osteogenesis

Abstract

Objective To determine the ratio of the main growth factors when using various methods of local stimulation of reparative osteogenesis.Material and methods The study consisted of two parts: in the first part a comparative analysis of the content of growth factors by ELISA was carried out (PDGF – platelet derived growth factor, TGF – transforming growth factor, VEGF – vascular endothelial growth factor, IGF – insulin-like growth factor, BMP6 and BMP7 – morphogenetic proteins 6 and 7), capable of stimulating reparative osteogenesis in blood plasma, plateletrich plasma, red bone marrow and bone autoregenerate. The second part presented the results of approbation of the autoregenerate obtained according to the original method in the framework of an acute experiment on animals.Results The most important cytokines affecting the process of reparative osteogenesis are fibroblast growth factor – FGF1 and bone morphogenetic protein 7 – BMP7. Based on the results of a comparative enzymelinked immunosorbent assay, it has been established that the autoregenerate, obtained by the original method, and a bone marrow aspirate concentrate have the highest osteogenic potential.Conclusion Autoregenerate is an effective and promising means of local stimulation of reparative osteogenesis, and its transplantation is a simple and highly effective procedure.
