Figure 6.
Cell death occurred within the graft midsubstance and there was limited cell repopulation. Images of the tendon graft within joint space at 1 week (A) and 4 weeks (B) postsurgery. Images are of tdTom channel (red) with DAPI counterstain (blue) overlaid on toluidine blue O image. Graft at 1 week possesses live cells near the surface of the graft (white arrow), while the graft was mostly acellular at 4 weeks with cellular portions coming from repopulating Gdf5-Cre;tdTom+ cells (yellow arrow) near the entrance to the bone tunnel. Scale bars: 200 μm.
