Effect of BFP-2 treatment on ALP, osteocalcin, CD44 and CD51 expression levels. BMSCs were treated with 1 μg ml−1 of BFP-2 or1 μg ml−1 of BMP-7 (as a positive control). After 24 h, immunofluorescence analyses were carried out using (a) anti-ALP (green), (b) anti-osteocalcin (green) and (c) anti-CD44 (red) antibodies. (d) CD44 and CD51 expression was measured by flow cytometry (green arrow: ODM only, pink arrow: ODM plus BFP-2). The data are representative of four independent experiments. Magnification, × 400.
