TET2 and ischemia: To investigate the role of TET2 in post‐ischemic angiogenesis in the hindlimb ischemia (HLI) model and better trace endothelial cells, endothelial cells specific TET2-deficient mice (TET2EC−KO; mTmG) were constructed, of which endothelial cells were labeled with GFP after being induced with tamoxifen (Fig. 3A).
