Effects of 5F from Pteris semipinnate L on growth of human pathological scars in nude mice / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of 5F from Pteris semipinnate L on the growth of human pathological scar in nude mice.</p><p><b>METHODS</b>5F from Pteris semipinnate L was administered at different doses in nude mouse models bearing human pathological scars. The morphology, histology, tumor growth factor-beta1 and type I collagen content of the scar tissues were examined after the administration.</p><p><b>RESULTS</b>Administration of 5F significantly reduced the volume of the implanted pathological scars in the nude mouse models, and histologically, the scar tissue exhibited a transition to the normal scar architecture with decreased TGF-beta1 and type I collagen content.</p><p><b>CONCLUSION</b>5F could effectively inhibit the growth of pathological scars in nude mice.</p>
