NCAM1 and dermatomyositis: Regenerative NCAM + fibers were found in similar proportion in both groups: 15.4% in ASM (16.4% in anti-Jo1; 11.7% in others) and 19.1% in DM (NS; Fisher’s test) (Figure 1C, D).Macrophages were observed in perimysium close to fascicles in ASM (Figure 1G), and in perimysium and perivascular areas in DM (Figure 1H).
