Effect of ND-ODA-Dex on macrophage gene expression. Gene expression of markers associated with M1, M2a, and M2c macrophages and angiogenesis were analysed. Log-transformed data are presented as mean ± SD. n = 3–4 from a single donor. **p < 0.01, ***p < 0.001, ****p < 0.0001. Significant differences in marker expression between M0, M1, and M2a groups are not noted for the sake of clarity.
