Abstract (original English)

Scar is a kind of skin fibroproliferative disease characterized by excessive repair of skin tissue and disorganized deposition of extracellular matrix resulting from deep dermal injury caused by burns or trauma. Scar is accompanied by symptoms such as itching and pain, which could lead to appearance damage and psychological disorders, and is one of the common diseases in burns and plastic surgery clinics. Currently, transplantation of adipose tissue and components is considered as one of the most cutting-edge treatments for scar. Adipose components transplantation includes transplantation of nanofat, adipose-derived stem cell matrix gel, stromal vascular fraction, and adipose-derived stem cell. More and more studies showed that adipose tissue and components possess the functions of tissue regeneration, extracellular matrix remodeling, and anti-fibrosis, which could improve the appearance and symptoms of scar by local transplantation. Therefore, this paper reviews the effects of adipose tissue and components transplantation on scar treatment, aiming to provide theoretical reference for adipose treatment of scar. 瘢痕是由烧伤或创伤导致皮肤真皮深层损伤引起的皮肤组织过度修复、细胞外基质沉积紊乱的一种皮肤纤维增生性疾病，伴有瘙痒、疼痛等症状，可导致患者外观毁损和心理障碍，是烧伤整形外科门诊常见的病种之一。当前，脂肪组织及脂肪成分移植被认为是瘢痕最前沿的治疗方法之一。脂肪成分移植包括纳米脂肪、脂肪来源干细胞基质胶、基质血管成分和脂肪源性间充质干细胞移植。越来越多的研究显示，脂肪组织及脂肪成分具有组织再生、细胞外基质重塑和抗纤维化的功能，局部移植可改善瘢痕的外观及症状。因此，本文就脂肪组织及脂肪成分移植在瘢痕治疗中的作用作一综述，旨在为瘢痕的脂肪疗法提
