tdTom+ cells exist within the knee but not tail tendons of Gdf5-Cre;R26R-tdTomato mice. The intact contralateral knee from an ACLR mouse that received demeclocycline injection (yellow in A) the day prior to sacrifice. Gdf5-Cre;tdTom+ cells exist within the synovial lining (white arrows in A1), cruciate ligaments (A1), epiphyseal bone (arrow head in A2), and bone marrow (arrow in A2). Conversely, the tail tendons from these mice possess very few Gdf5-Cre;tdTom+ cells (B). Scale bars: 200 μm.
