On the other hand, recent studies showed that ECP did not induce cell death but inhibited the growth of cancer-derived cells. Our previous study indicated that human ECP enhanced differentiation of rat neonatal cardiomyocytes and stress fiber formation in Balb/c 3T3 mouse fibroblasts, while the effects of human ECP on human fibroblasts are unknown. [Objective] : The present study was performed to determine the effects of human ECP on cytokine expression in human fibroblasts by protein array. [Methods] : The effects of recombinant human ECP (rhECP) on normal human dermal fibroblasts (NHDF) were examined by assaying cell growth. Furthermore, cytokine expression of NHDF stimulated by ECP, which could influence cell growth, was evaluated by protein array. [Results] : ECP was not cytotoxic but enhanced the growth of NHDF. The peak rhECP concentration that enhanced the cell counts by 1.56-fold was 100 ng/mL, which was significantly different from cultures without ECP stimulation (ANOVA/Scheffefs test, P < 0.05). Array analyses indicated that ciliary neurotrophic factor (CNTF), neutrophilactivating peptide (NAP)-2, and neurotrophin (NT)-3 were significantly upregulated in NHDF stimulated with 100 ng/mL ECP compared to those without stimulation. [Conclusion] : ECP is not cytotoxic but enhances the growth of NHDF. CNTF, NAP-2, and NT-3 were suggested to be involved in enhancing the growth of NHDF. These findings will contribute to determination of the role of ECP in allergic inflammation.
