An analysis and a synthesis of published and original experimental evidence have been performed with a view to providing a global qualitative and quantitative description of the proliferation of monocyte precursors in murine bone marrow. Two versions of a mathematical model are proposed. The first consists of two dividing generations of granulocyte‐macrophage colony‐forming cells (GM‐CFC) and two dividing generations of macrophage colony‐forming cells (M‐CFC), differentiating into promonocytes (PM) and then into monocytes (MC). The second version consists of two generations of GM‐CFC and three generations of M‐CFC, followed by PM and MC. Both are compatible with experimental data, and further evidence is needed to elaborate a unique representation. The kinetic constants have been taken from published material whenever possible and estimated from available data and model kinetics in the case of unknown quantities. The models are applied to a pulse labeling assay, and calculated labeled subpopulations are compared with experimental values. Agreement is satisfactory for both versions in the case of MC, while a calculated PM labeling index falls more rapidly than the experimental values. However, inconsistency also exists between PM and MC experimental data.
