Figure 3: Mesenchymal cells in the injury site contain IL-17A-responsive PαS cells.

(a) The ratio of IL-17RA+ cells in CD45−Ter119−CD11b−CD31−CD34− mesenchymal cells in the repair tissues of non-treated and injured mice (n=6 per time point). (b) The expression of MSC markers on IL-17RA+ mesenchymal cells of the repair tissue (n=3−6). Most of the IL-17RA+ mesenchymal cells were PαS cells positive for both platelet-derived growth factor receptor-α (PDGFRα) and Sca-1. Statistical analysis was carried out using Student’s t-test. Error bars denote the mean±s.e.m. *P<0.05.
