According to commonly known linage markers, we were able to identify MM cells (Cited1, Cd63, Dct), fibroblasts (Mgp, Dcn, Col1a1), blood‐(BEC; Pecam, Cd34, Vwf), and lymphatic endothelial cells (LEC; Lyve1, Tmem100, Cldn5), as well as immune cells including macrophages (Lyz2, Chil3, Ccl6), neutrophils (S100a9, S100a8, Il1b), B cells (Cd79a, Cd79b, Igkc), NK cells (Nkg7, Gzma, Ccl5), and T cells (Cd3g, Il7r, Trac). The gene discussed is CD34; the disease is Miyoshi myopathy.
