S ummary. Total cellular RNA from a variety of myeloid and lymphoid cell populations, normal and leukaemic, was analysed for the expression of a human cellular one ‐gene, c‐ fes , by northern blot hybridization assays. The probe used was a molecularly cloned human DNA sequence homologous to the 5′ terminal sequence of v‐ fes . All the myeloid cellular populations expressed the c‐ fes gene. In some cell populations at an advanced stage of differentiation (circulating leucocytes from Chronic myeloid leukaemia (CML), HL60 cells induced to differentiate by retinoic acid) the level of expression was even higher than in early stages of the myeloid lineage (blast cells from AML, uninduced HL60 cells). No transcript of the c‐ fes gene was detected in the different lymphoid populations studied. The occurrence of an RNA complementary to the c‐ fes sequence appears sufficiently characteristic of a myeloid population to distinguish it from a lymphoid population, normal and leukaemic.
