Human dermal blood endothelial cells were cultured with either vehicle control (PS), IL-17 (1ng/ml), TNF-alpha (2ng/ml), IFN-gamma (2ng/ml), or combinatations. RN was isolated after 12 hours of exposure to cytokines, and expression of various chemokines was determined using qrt-pcr (as described in the materials and methods). Error bars represent the standard error of the mean. Significance was determined by comparison of cytokine treatment versus PS, p <.5, p <.1 using a paired t-test. N=3.
