Figure 5.
Functional status of the newly differentiated cells from in vitro PBMC-derived CD14+ cells was investigated by estimating cytokine levels in the cell culture media after 48 h of SF induction; in the figure, the X-axis denotes different KL grades of SF samples used for the induction, while the Y-axis represents the level of each selected cytokine in pg/mL; in the selected cytokines panel, IL-1β and TNF-α are M1-macrophage-specific, and IL-4 and IL-10 are M2-specific cytokines; ** p < 0.01, *** p < 0.001, as compared to control.
