Although CD47 is widely expressed on the surface of a broad range of cell types, high levels of CD47 have also been observed in haematological cancers such as acute myeloid leukaemia (AML), ALL, CLL, multiple myeloma (MM), myelodysplastic syndrome (MDS), DLBCL, MCL, and MZL [174,177,178,179,180,181,182]. The gene discussed is CD47; the disease is acute lymphoblastic leukemia.
