The purpose of this study was to characterize the molecular phenotype that occurs during the profound morphological shift of cultured osteogenic cells upon treatment with fibroblast growth factor-2 (FGF2). A time course of treatment with FGF2 was performed on an osteoblast cell line, primary bone marrow stromal cells and an osteocyte-like cell line. Morphologic changes were recorded, and gene profiling was carried out by real time PCR. By 8 hours of FGF2 treatment, there is a striking morphological shift of osteoblast and stromal cells to an elongated dendritic-like morphology that is remindful of osteocytes. In osteoblasts treated with FGF2, this morphologic shift is preceded by an induction of several osteocyte markers, including dentin matrix protein 1 (>20-fold) and E11 (>5-fold). There is a transient increase in the gene expression of sclerostin (3.5-fold) and PHEX (2.5-fold). Sclerostin regulation by FGF2 is complex, as gene expression becomes markedly inhibited by FGF2 at times points after 8 hours of treatment before rebounding at day 12. Analogous modulation of osteocyte markers is seen in bone marrow stromal cells and MLO-Y4 osteocyte-like cells. In conclusion, this study shows that FGF2 can regulate the transition of osteogenic cells towards the osteocyte lineage, as well as, regulate the expression of critical genes in osteocytes.
