SDF-1α/OPF/BP Composites Enhance the Migrating and Osteogenic Abilities of Mesenchymal Stem Cells

Figure 1

Three-dimensional migration assay of MSCs on the four groups of SDF-1α/OPF/BP composites. (a) Schematic illustration of the three-dimensional migration model. (b) 3D spheroid migration assay showed that the migrating distances of the SDF100 and SDF200 groups were higher than those of the SDF50 and control groups. (c) Calcein AM staining of 3D spheroids after 72 hours of culture with SDF-1α/OPF/BP composites. The red line indicates the distance of migrating cells.
