Density of microchimeric cells by immunophenotype in the muscle of patients with juvenile idiopathic inflammatory myopathies (JIIM), muscular dystrophy (MD) and noninflammatory controls (N-IC). Data are presented as mean ± standard error of the mean for each immunophenotype. No microchimeric cells were identified that were positive for CD20, CD45RO or CD83 (data not shown). JIIM juvenile idiopathic inflammatory myopathy (n = 10), MD muscular dystrophy (n = 9), N-IC noninflammatory controls (n = 10). ^* p = 0.01; ^** p = 0.025; ^*** p = 0.003; ^**** p = 0.006. (a) Total microchimeric cells in tissues; (b) CD3 positive microchimeric cells; (c) CD4 positive microchimeric cells; (d) CD8 positive microchimeric cells; (e) HLA class II positive microchimeric cells; (f) CD25 positive microchimeric cells; (g) CD45RA positive microchimeric cells; (h) CD123 positive microchimeric cells
