Colloids Surf B Biointerfaces:SFHs可以作为一种有效的治疗剂用于治疗肥厚性疤痕

目前治疗肥厚性疤痕的药物存在着疗效有限、恢复速度慢的瓶颈。丝纤维素(SF)因其能促进烧伤和皮肤伤口愈合而受到关注,但其对肥厚性疤痕的治疗效果尚未得到深入研究,研究结果已在线发表于Colloids Su

目前治疗肥厚性疤痕的药物存在着疗效有限、恢复速度慢的瓶颈。丝纤维素(SF)因其能促进烧伤和皮肤伤口愈合而受到关注,但其对肥厚性疤痕的治疗效果尚未得到深入研究,研究结果已在线发表于Colloids Surf B Biointerfaces
我们制备了不同SF浓度(1.5%、3%和6%)的SF基水凝胶(SFHs),并对其理化性质进行了表征。细胞实验表明,这些SFHs在体外具有良好的生物相容性。进一步的兔子动物实验表明,与阴性对照组相比,SFH(3 %)处理组的耳朵上的疤痕更薄,颜色明显变浅。此外,用SFHs治疗后,降低了胶原纤维的密度,使其有序排列。研究发现,SFHs的治疗效果是由于α-平滑肌肌动蛋白的表达水平降低所致。
综上所述,这些结果首次证明了SFHs可以作为一种有效的治疗剂用于治疗肥厚性疤痕。
