The ranked position (out of 22,690 probe sets assayed) of Northern-blot-validated transcript probe sets and references highlighting their role in normal or malignant hematopoiesis are shown. For transcripts linked to multiple probe sets, the first occurrence of transcript in the ranked probe set list is shown.
