 Hypertrophic scars are the consequences of the aberration of normal wound healing. To date, therapeutic strategies for abnormal scarring have been unsuccessful. ‎‏The abnormal extracellular‎ matrix is one of the most important contributing factors to ‎hypertrophic scars. ‏Scrophularia striata has been used in Iranian folk medicine for the treatment of burn wounds. ‏The plant extract accelerates wound healing and attenuates scar formation.

 The study was performed to investigate the effects of Scrophularia striata hydroalcoholic extract (SSE) on MMP1, MMP8, fibronectin, collagen type І, and total collagen produced by human skin fibroblasts in the culture medium.

 The effects of SSE on the expression of MMP1, MMP8, fibronectin, and collagen type І in human skin fibroblast (HSF) were evaluated using Q-PCR and Western blotting methods. In addition, the effect of SSE on the total collagen content was measured in cultured HSF using Red Sirius Kit.

 SSE significantly induced the expression of MMP1 and suppressed the production of fibronectin at the mRNA and protein levels. The total collagen content was significantly lower in SSE-treated cells than in untreated cells. SSE did not have any significant effect on MMP8 and collagen type І expression.

 The results of this study revealed that SSE could modulate the extracellular matrix turnover and had the potential for the prevention and treatment of hypertrophic scars.
