Following our observations that A-myb is expressed in a restricted subset of normal mature human B lymphocytes , with the phenotype CD38+, CD39-, slgM- , we have now investigated the pattern of A-myb expression in neoplastic B cells representating the whole spectrum of B-cell differentiation and compared it to that of c-myb and B-myb .
 ( DNA: A-myb, None) , ( DNA: A-myb, None) , ( cell type: B cells, None) , ( DNA: B-myb, None) , ( DNA: c-myb, None) , ( cell type: mature human B lymphocytes, None)
