Expression of markers of inflammation in cultured tendon-derived stromal cells after cytokine treatment. Tendon stromal cells were derived from healthy hamstring (n=6 donors), tendinopathic (n=6 donors) or ruptured Achilles (n=6 donors). (A) PDPN expression after IL-1β treatment (10 ng/mL) for 24 hours determined by flow cytometry. (B) Expression of PDPN mRNA after IL-1β treatment (10 ng/mL) for 24 hours. Expression of interferon target genes IRF5 (C) and IRF1 (D) after IFNγ treatment (20 ng/mL) for 24 hours. Gene expression is shown normalised to β-actin; bars represent median values. **P<0.01, *P<0.05. mRNA, messenger RNA; PDPN, podoplanin.
