Figure 2: Confocal fluorescence microscopy (a–c) of representative cells located in the cambium layer and stained for markers of the osteoblast lineage. Nuclei were stained with DAPI (blue). (a) Stromal cells stained positive for vimentin (green). (b) Stromal stem cells stained positive for Stro-1(green). (c) Cells of the osteoblast lineage stained positive for Cbfa-1/Runx2 (green).
