PURPOSE:To evaluate the level of cytokines and keratinocyte growth factor (KGF) or Fibroblast Growth Factor 7 (FGF-7) in the culture medium of cultured human dermal fibroblasts from patients with large burn in comparison to small burn.METHODS:Fibroblasts of 10 patients (four large burns, four small burns and two controls) were initiated by the enzymatic method using collagenase. Cytokines and KGF in the supernatant of the culture medium was measured by, respectively, flow cytometry using Cytometric Bead Array Human Inflammation kit (CBA, BD Biosciences, USA) and the enzyme immunoassay method using the Quantikine (r) Human KGF. The experiments were performed in triplicate.RESULTS:The expression of IL-12 protein in patients with large burns showed a tendency to increase. IL- 6, IL- 10, and IL- 1beta were observed no difference. For IL - 8, TNF - alpha and KGF was observed a significant difference between the expression in large and small burned patient.CONCLUSION:That IL-8, TNF-alpha and KGF showed higher expression in cultured fibroblasts of large burned patients.
