Figure Lengend Snippet: A Experimental workflow used to generate reference macrophage states. BM precursors were differentiated with GM-CSF or M-CSF and skewed with IFN-γ, IL-4, IL-10, or TGF-β, yielding eight cytokine × ontogeny macrophage states. Macrophages were harvested on day 7 for live-cell imaging, morphological analysis, and T-cell co-culture assays. Color code: Control (gray), IFN-γ (blue), IL-4 (green), IL-10 (yellow), TGF-β (orange-red). B Time-lapse live microscopy of Arg1-YFP (green) and Spp1‑IRES‑tdTomato (red) reporter macrophages. Curves plot mean fluorescence over 100 h for each cytokine in M-CSF and GM-CSF cultures (representative of three independent experiments; six imaging fields per well per condition were analyzed). Timepoint 0 represents the time of cytokine stimulation (day 3 of culture). IL-4 induces a progressive ARG1 signal only in M-CSF macrophages; IL-10 (and weakly TGF-β) induces SPP1 almost exclusively in GM-CSF macrophages; unpolarized and IFN-γ macrophages maintain low expression of both reporters throughout. C Representative fluorescence micrographs showing label-free cell classification based on automated quantification of cell area (primary metric for GM-CSF macrophages) and eccentricity (primary metric for M-CSF macrophages). Images were acquired using live-cell imaging (Incucyte) and analyzed using the Advanced Label-Free Classification Module. Pseudo-color overlay indicates morphometric values: cyan = low (round cells with low area/eccentricity), magenta = high (elongated or large cells with high area/eccentricity). Representative images shown for each cytokine treatment in both M-CSF and GM-CSF cultures. Scale bar = 200 µm. D Z -scored classification data from four independent biological replicates (open circles). Eccentricity (primary morphological discriminant for M-CSF macrophages) and cell area (primary morphological discriminant for GM-CSF macrophages). Z -scores were calculated across all conditions to enable direct comparison. E Flow-cytometric contour plots for CD11b and MHC-II expression in GM-CSF macrophages across all treatment conditions and CFSE dilution histograms of OT-II specific CD4+ T cells co-cultured with peptide-pulsed GM-CSF macrophages. F Bar graphs of the cumulative data showing the fraction of OT-II CD4+ T cells that underwent proliferation. Data represent mean ± SEM from n = 6 independent cultures, one-way ANOVA Tukey‒Kramer posttest corrected for multiple comparisons (Control vs IL‑10 p < 0.0001; control vs TGF‑β p < 0.0001; IFN‑γ vs IL‑10 p < 0.0001; IFN‑γ vs TGF‑β p < 0.0001; IL‑4 vs IL‑10 p < 0.0001; IL‑4 vs TGF‑β p < 0.0001. All other comparisons, including control vs IFN‑γ, control vs IL‑4, IFN‑γ vs IL‑4, and IL‑10 vs TGF‑β were not significant ( p > 0.05; ns).

Figure Lengend Snippet: A GFP‑MC38 cells were cultured alone or mixed 1:1 with cytokine‑polarized M‑CSF or GM‑CSF macrophages in ultra‑low‑attachment plates and imaged for 10 days. Macrophages were pre-polarized for 7 days as described in Fig. , then washed and mixed with tumor cells. Spheroids formed within 24 h and were imaged every 2–4 h for 10 days using an Incucyte S3 live-cell analysis system. GFP fluorescence intensity integrated across the entire spheroid area was used as a real-time readout of spheroid size. For each treatment condition 9–10 spheroids were analyzed. B M-CSF macrophages : Integrated GFP fluorescence intensities across the spheroid area over time (mean ± SE of 8–10 spheroids analyzed within one representative experiment) and area under the curve (AUC), reflecting cumulative spheroid growth over the 10-day period. Individual data points (open circles) show replicate values. one-way ANOVA Dunnett posttest corrected for multiple comparisons (Control vs IFN‑γ p = 0.0110, control vs all other cytokines p < 0.0001. C Representative fluorescence micrographs for each condition from the time course in B . Each image shows a single spheroid. Scale bar = 0.5 mm. D GM-CSF macrophages: Time-course analysis and AUC quantification identical to B . Data are the mean ± SE of 9 biologically independent spheroids from one independent experiment. Individual data points represent individual spheroids (Control vs IFN-γ p = 0.9993 (ns), control vs IL-4 p = 0.0269, control vs all other cytokines p < 0.0001). E GM-CSF macrophages: Representative fluorescence micrographs for each condition from the time-course experiment in D . Each row shows a representative spheroid over time. Scale bar = 0.5 mm.

Figure Lengend Snippet: A GFP‑MC38 cells were cultured alone or mixed 1:1 with cytokine‑polarized M‑CSF or GM‑CSF macrophages in 96-well ultra‑low‑attachment or 24-well microwell plates. Three days post formation, spheroids were embedded in a laminin-rich matrix ( t = 0 h) and invasion was visualized by Incucyte live-cell imaging or confocal microscopy. B Confocal micrographs acquired 24 h after embedding show dense, finger‑like projections invading into the matrix in spheroids containing protumoral macrophages (IL-4 polarized M-CSF macrophages (green), IL-10 polarized GM-CSF macrophages (yellow)). Scale bar = 100 µm. C M-CSF macrophages: Quantitative spheroid invasion assay. Cell invasion was measured with an Incucyte live cell imaging system every 4 h. The invading cell front was automatically segmented and quantified over time. Data are the mean ± SE of 3 biologically independent spheroids analyzed within one representative experiment. AUC quantification was analyzed by one-way ANOVA Dunnett posttest corrected for multiple comparisons (Control vs IFN-γ p = 0.6900 (ns), control vs IL-4 p < 0.0001, control vs IL-10 p = 0.3239 (ns), control vs TGF-β p < 0.0001, control vs TC p = 0.6665 (ns)). Representative inverted bright field images for each condition are shown. Scale bar = 0.5 mm. D GM-CSF macrophages: Analysis identical to C ( n = 4 replicates per condition) (Control vs IFN-γ p = 0.0714 (ns), control vs IL-4 p = 0.7959 (ns), control vs IL-10 p < 0.0001, control vs TGF-β p < 0.0001, control vs TC p = 0.0954 (ns)). Scale bar = 0.5 mm.
