Morphometric analysis of neointimal formation in transplanted cardiac graft exposed with Thrombomodulin (TM) and normal saline. a, b Results of lumen area (μm2) in the left coronary arteries (LCA) and the right coronary arteries (RCA) of each group 2 and 4 weeks after grafting. c, d Results of SI (stenosis index) in LCA and RCA of each group 2 and 4 weeks after grafting. LCA, left coronary artery; nTx, untreated; RCA, right coronary artery; SI, stenosis index. *p < 0.05, #p < 0.01, and ##p < 0.005 for difference between two groups
