U937 cells are a model cell line used in biomedical research.[1] They were isolated from the histiocytic lymphoma of a 37-year-old male patient and are used to study the behaviour and differentiation of monocytes. U937 cells mature and differentiate in response to a number of soluble stimuli, adopting the morphology and characteristics of mature macrophages.

U937 cells are of the myeloid lineage and so secrete a large number of cytokines and chemokines either constitutively (e.g. IL-1 and GM-CSF) or in response to soluble stimuli. TNFα and recombinant GM-CSF independently promote IL-10 production in U937 cells.

[2] IFNγ increases the expression of chemokine receptors (CCR1, CCR3 and CCR5) as well as that of nuclear receptors for melatonin.[3] IFNγ treatment enhances thrombin-induced IL-8 production[4] and is required for the melatonin-induced production of IL-6.[5]

U937 can be grown in DMEM or 1640 medium plus 10% fetal bovine serum.

Atromentin induces apoptosis in human leukemia U937 cells.[6]

The HLA alleles present in U937 cells are HLA-A*03:01, A*31:01, B*18:01, B*51:01, Cw*01:02 and Cw*07:02.[7]
