Abstract:
To investigate the effects of prostaglandin E1(PGX1) in prevention of proliferative scar formation, we cultured fibroblasts of normal skin (NS), hypertrophic scar (HS) and keloid (KL) tissues obtained from patients. We have compared type I collagenase production of cultured fibroblasts from normal skin, hypertrophic scar, and keloid tissues under various concentrations of PGE1. Our results demonstrate that type I collagenase production was significantly increased after addition of PGE1 in HS and KL, but not NS. Type I collagenase production of HS and KL fibroblasts were increased similarly in 10M and 10M of PGE1 and maximally increased in the concentration of 10M. This promotive effects of PGE1 on the production of type I collagenase was larger in KL than in HS. These results also suggest that PGE1 may play the promotive effects on type I collagenase production in dose-dependent manner. PGE1 may have a role in the prevention of hypertrophic scar and keloid by enhancing the production of type I collagenase of HS and KL fibroblasts. The promotive effects of PGE1 on type I collagenase production was variable depending on its concentration, and its effects was maximum in certain optimal condition. The maximally effective concentration of PGE1 in the prevention of proliferative scar formation should be searched in further investigations for clinical use.
