增生性瘢痕是一种主要的术后并发症,可导致患者严重的毁容和功能障碍,并且由于其高复发率通常需要多次手术翻修。伤口上过度的机械负荷是肥大性瘢痕形成的重要诱因。在这项研究中,我们证明,皮内注射单一细胞外基质(ECM)分子-纤维调节蛋白(FMOD)蛋白-可以显着减少瘢痕大小,增加拉伸强度,并改善正常甚至过度机械负荷红色杜洛克猪伤口模型中的真皮胶原蛋白结构组织。由于猪皮被美国食品药品监督管理局认定为最接近人类皮肤的动物等效物,并且由于红色杜洛克猪显示出与人类增殖性瘢痕和肥大性瘢痕非常相似的瘢痕,因此基于FMOD的技术具有很高的转化潜力和适用性,适用于患有瘢痕的人类患者,特别是肥大性瘢痕。
Hypertrophic scarring is a major postoperative complication which leads to severe disfigurement and dysfunction in patients and usually requires multiple surgical revisions due to its high recurrence rates. Excessive‐mechanical‐loading across wounds is an important initiator of hypertrophic scarring formation. In this study, we demonstrate that intradermal administration of a single extracellular matrix (ECM) molecule—fibromodulin (FMOD) protein—can significantly reduce scar size, increase tensile strength, and improve dermal collagen architecture organization in the normal and even excessive‐mechanical‐loading red Duroc pig wound models. Since pig skin is recognized by the Food and Drug Administration as the closest animal equivalent to human skin, and because red Duroc pigs show scarring that closely resembles human proliferative scarring and hypertrophic scarring, FMOD‐based technologies hold high translational potential and applicability to human patients suffering from scarring—especially hypertrophic scarring.
