CD68 and CD163 expression in patients without and with seroma formation. CD68 expression in the TME of a patient without (A) and with (B) seroma development and differences illustrated within a dot plot (C). CD163 expression in the TME of a patient without (D) and with (E) seroma development and differences illustrated within a dot plot (F). CD68 expression in the SAT of a patient without (G) and with (H) seroma development and differences illustrated within a dot plot (I). CD163 expression in the SAT of a patient without (J) and with (K) seroma development and differences illustrated within a dot plot (L). Scale bars represent 100 μm. The dot plots visualize the distribution of positive cells in patients without and with seroma development. The horizontal lines represent the median values. *p < 0.05. Correlation analysis of macrophages (CD68 + cells) counted in the TME and SAT (M) and Correlation analysis of CD163 + cells counted in the TME and SAT (N).
