To analyze PBMC-associated TF PCA expression among subtypes of the French–American–British (FAB) classification, AML patients (n = 69) were grouped in those with M0/M1/M2 (n = 32), M3 (n = 5), M4/M5 (n = 19) or secondary AML (n = 13) (Fig. 1b). The gene discussed is TF; the disease is acute myeloid leukemia.
