Effects of ADSCbFGF treatment on chondrogenesis and osteogenesis during fracture healing. Col2‐CreERT mice were crossed with tdTomato‐mCherry reporter mice so that Col2+ cells and their descendants expressed tdTomato. Cre was activated by IP injection of tamoxifen (3 mg/kg × 2 days) prior to femoral fracture. Mice were sacrificed at days 7 or 14. Scale bar 100 µm. Abbreviations: ADSC, adipose‐derived mouse MSCs; bFGF, basic fibroblast growth factor; PBS, phosphate buffered saline.
