[摘要]慢性创面愈合过程机制复杂,涉及炎性反应、成纤维细胞异常增殖、胶原的形成与沉积、创面血管化和皮肤再上皮化等过程,目前临床缺乏理想的治疗方法。近年来,干细胞的应用在慢性创面的治疗方面备受瞩目,其主要优点是避免了潜在的有害的外科手术过程,避免皮肤移植或皮瓣等手术带来的负荷等。本文就胚胎干细胞、骨髓间充质干细胞、脂肪干细胞、诱导多能干细胞对慢性创面的治疗机制及相关研究进展作一综述。

Abstract: The mechanism of chronic wound healing is complex, which involves inflammatory reaction, abnormal proliferation of fibroblasts, collagen formation and deposition, wound vascularization and skin re epithelialization. At present, there is no ideal treatment method in clinic. In recent years, the application of stem cells has attracted much attention in the treatment of chronic wounds. Its main advantages are avoiding potential harmful surgical procedures and avoiding skin graft or flap operation. In this paper, the treatment mechanism, advantages and disadvantages of embryonic stem cells, bone mesenchymal stem cells, adipose-derived stem cells and induced pluripotent stem cells in chronic wounds were reviewed.
Key words: chronic wound; stem cells; vascularization; regeneration; healing
慢性难愈性创面简称慢性创面,是指经规范临床治疗4~8周后仍难愈合或不愈合的创面。在中国,伴随着人口老龄化及生活水平的提高,糖尿病、下肢静脉溃疡等发病率逐年上升,慢性创面发生率越来越高。近年来,干细胞的应用在慢性创面的治疗方面备受瞩目,干细胞治疗的主要优点是可取代部分手术治疗,从而避免皮肤移植或皮瓣等手术为老年患者带来的身体负担及并发症。干细胞的应用可为有效治疗创伤性皮肤缺损和严重烧伤导致的软组织缺损以及治疗如糖尿病、下肢静脉性溃疡等疾病导致的慢性创面提供新的治疗方法。本文就近年来难愈创面的各种慢性创面的干细胞治疗技术,如:胚胎干细胞(Embryonic Stem Cells,ESCs)、间质干细胞(Mesenchymal Stem Cells,MSCs)尤其骨髓间充质干细胞(Bone Mesenchymal Stem Cells,BMSCs)、脂肪干细胞(Adipose-Derived Stem Cells,ADSCs)、诱导多能干细胞(Induced Pluripotent Stem Cells,IPSCs)等研究進展作一综述。……
