(A) Expression of transforming growth factor‐β1 (TGF‐β1), vascular endothelial growth factor (VEGF), collagen I and collagen III mRNAs, as revealed by agarose gel electrophoresis of reverse transcription polymerase chain reaction (RT‐PCR) products. (B) Densitometric analysis of mRNA expression. The expression of TGF‐β1, VEGF, collagen I and collagen III increased in early scars, peaked in proliferative scars and decreased in regressive and mature scars (n = 5). * indicates P<0·05. (NS, ES, HS, RS and MS represent normal skin, early scars, proliferative scars, regressive scars and mature scars, respectively).
