These blast cells express lineage-specific transcription factors such as GATA-1 common to these lineages and frequently express erythroid-specific mRNAs such as gamma-globin and erythroid delta-aminolevulinate synthase ( ALAS-E ), indicating that most of the blasts in M7 and TMD cases have erythroid and megakaryocytic phenotypes .
