Results show that LPS primed MSCs injected into wounds provoke increased expression of MIP/KC in endogenous neutrophils. MIP/KC represents functional homologues of IL-8 in mice and are known as neutrophil chemoattractant. Similar results were found for IL-1β, which is a strong chemoattractant for neutrophil recruitment and bacterial clearance. In addition, LIX which shares 63% amino acid sequence identity with human GCP-2/CXCL6, a chemoattractant for neutrophils. The graphs display numbers of double positive cells for Ly6G MIP/KC, IL-1β and LIX, respectively. PBS and non-primed MSCs injected wounds served as controls. To facilitate comparison, areas inside the rectangles are shown at 5x magnification in the insets. Statistical analysis was performed using one way ANOVA, values are represented as mean ± SEM, six biological replicates. Scale bars: 50µm.
