研究目的:

1.评估两种治疗技术:浓缩纳米脂肪与脱细胞脂肪组织外基质在下肢慢性难愈性创面的疗效,并力争建立治疗慢性难愈性创面的新技术。 2.从临床治疗的角度阐明:纳米脂肪这种基质细胞混合物局部移植过程中天然的基质成分对干细胞发挥再生性修复作用的影响,为干细胞负载外基质作为干细胞局部移植的重要方法诱导组织原位组织再生提供可靠的临床证据。  

Objectives of Study:

1. To evaluate the efficacy of concentrated nano-fat and decellularized adipose tissue extracellular matrix in the treatment of hard-to-heal wounds of lower extremities, and to establish a new technique for the treatment of chronic refractory wounds. 2. From the perspective of clinical treatment to clarify the effect of natural matrix components on the regenerative function of stem cells during local transplantation of nano-fat, a mixture of stromal cells, and provides reliable clinical evidence for the induction of in situ tissue regeneration by stem cells transplanting loaded with extracellular matrix.
