Indeed, all MM cell lines tested uniformly express PSGL-1 and CD147, and are variably CD44 positive, all potential glycoforms to express E-selectin ligands.17, 30, 31, 36, 37 Thus, it is possible that multiple known glycoprotein and/or glycolipids function as E-selectin ligands on MM cells. The gene discussed is BSG; the disease is Miyoshi myopathy.
