DDX53 and neoplasm: Comparison of pixel derived spectra at equivalent timepoints derived from 4T1- and CT26.WT mice harboring Rba. capsulatus SB1003 cells show that the change in the spectral signature is less pronounced in CT26.WT mice, which might reflect a lower density of tumor-associated macrophages32 (Figs. 1d, i, 3b as well as Supplementary Figure 14).
