Concentrated Growth Factors (CGF) Induce Osteogenic Differentiation in Human Bone Marrow Stem Cells

Osteogenesis is a complex physiologic process that occurs during development as well as during damaged bone regeneration. This process requires several growth factors that act on stem cell populations, including Bone Marrow Stem Cells (BMSC). The present study fits into the research field for safe improvement of cell osteogenesis induction. In this context there is a great interest on an autologous and biocompatible blood derived product, named Concentrated Growth Factor (CGF). In particular, the ability of CGF to induce osteogenic differentiation of human BMSC (hBMSC) in vitro was here investigated. The osteogenic differentiation was evaluated measuring typical osteogenic markers such as alkaline phosphatase enzyme activity, matrix mineralization of hBMSC, and expression of some osteogenic-related genes. The results show that CGF alone is able to induce osteogenic differentiation of hBMSC. This finding opens up further, interesting perspectives in the biotechnological use of CGF in the tissue regeneration field.
