Perception of the adipose tissue has changed dramatically over the last few decades. Identification of adipose-derived stem cells (ASCs) ultimately transformed paradigm of this tissue from a passive energy depot into a promising stem cell source with properties of self-renewal and multipotential differentiation. As compared to bone marrow-derived stem cells (BMSCs), ASCs are more easily accessible and their isolation yields higher amount of stem cells. Therefore, the ASCs are of high interest for stem cell-based therapies and skin tissue engineering. Currently, freshly isolated stromal vascular fraction (SVF), which may be used directly without any expansion, was also assessed to be highly effective in treating skin radiation injuries, burns, or nonhealing wounds such as diabetic ulcers. In this paper, we review the characteristics of SVF and ASCs and the efficacy of their treatment for skin injuries and disorders.
在过去几十年中,人们对脂肪组织的认知发生了巨大变化。脂肪来源干细胞(ASC)的鉴定最终改变了这种组织的范式,使其从一个被动的能量储存库转变为一种具有自我更新和多能分化特性的有前景的干细胞来源。与骨髓来源干细胞(BMSC)相比,ASC更容易获取,并且其分离能产生更高数量的干细胞。因此,ASC在基于干细胞的治疗和皮肤组织工程中备受关注。目前,新鲜分离的基质血管成分(SVF)可直接使用而无需任何扩增,经评估其在治疗皮肤放射性损伤、烧伤或诸如糖尿病溃疡等难愈合伤口方面也非常有效。在本文中,我们综述了SVF和ASC的特性以及它们治疗皮肤损伤和疾病的疗效。
