AbstractThis report indicates that retention fluid from blisters of partial skin thickness burns, which contains relatively large amounts of cytokines and growth factors, stimulates the wound healing process. Although epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) levels were low, relatively large amounts of cytokines including platelet derived growth factor (PDGF), interleukin (IL-6) and transforming growth factor (TGF) alpha were present and these exercised stimulatory effects on wound healing. TGF beta, which plays an important role in collagen metabolism and in scar formation, was also detected. Contrary to our expectations, IL-1 alpha and beta, both of which initiate inflammation, were detected at relatively low levels whereas IL-8 levels were rather high. Various cytokines were shown to coexist in a balanced state in the retention fluids, suggesting that epithelialization might be regulated via a cytokine network operating on the wound surface. The growth of keratinocytes in culture significantly increased with the addition of 1 per cent or more of blister fluid to the medium.
