The upper scheme depicts the experimental design. Representative microphotographs show that injection of LPS primed MSCs into wounds increased the expression of CXCL6, IL-8 and IL-1β. Graphs display numbers of double positive cells for h-β2M + CXCL6, h-β2M + IL-8 and h-β2M + IL-1β, respectively. MSCs injected wounds served as controls. Statistical analysis was performed using unpaired t-test, values are represented as mean ± SEM, six biological replicates. To facilitate comparison, areas inside the rectangles are shown at 5x magnification in the insets. Es, eschar on wound margin; wm, wound margin; scale bars: 50µm.
