Fig. 1. RUNX2 remains bound on mitotic chromosomes throughout mitosis.
U2OS human osteosarcoma cells were transfected with EGFP-RUNX2 and mRFP-Histone H2B. Mitotic cells were located using mRFP-Histone H2B and imaged through mitosis. RUNX2 punctate foci as well as diffuse RUNX2 staining on chromosomes were clearly evident in prophase, metaphase, anaphase and telophase. Left column—EGFP-RUNX2; middle column—mRFP-H2B and DIC in insert for comparison; right column—the merged image. Size bar is 10 μm.
