Abstract

Over the last decades, there has been ongoing and evolving research concerning regenerative medicine, specifically, stem cells. The most common source of adult mesenchymal stem cells (MSCs) remains the adipose tissue and the easiest way to obtain such tissue is lipoaspirate. The fatty tissue obtained can be processed either in an enzymatic way, which is time-consuming and expensive and carries several dangers for the viability of the stem cells included, or with mechanical means which are fast, inexpensive, yield enough viable cells, and can be readily used for autologous transplantation in one-stage procedures. Herein, we demonstrate our non-enzymatic method for obtaining adipose-derived stromal vascular fraction comprising MSCs. The stromal vascular fraction was isolated via centrifugation, and the characteristics and numbers of the cells isolated have been tested with flow cytometry assay, cell culture, and differentiation. Over 91% of viable MSCs were isolated using the mechanical method. The cells retained the ability to differentiate into osteocytes, adipocytes, and chondrocytes. The method presented is simple, requiring no special equipment, and yields a viable population of stem cells in large numbers. These cells can be readily used in several operations (orthopedic, dentistry, fistulas, etc.) making feasible "one-stage" procedures, thus proving their benefits for the patient and the health care system.

摘要

在过去几十年里,关于再生医学,特别是干细胞的研究一直在进行且不断发展。成人间充质干细胞(MSCs)最常见的来源仍然是脂肪组织,而获取此类组织最简单的方法是抽脂。所获得的脂肪组织既可以采用酶法处理,这种方法既耗时又昂贵,而且对其中所含干细胞的活力存在诸多风险;也可以采用机械方法,这种方法快速、廉价,能产生足够数量的活细胞,并且可以在一期手术中直接用于自体移植。在此,我们展示了我们获取包含MSCs的脂肪来源基质血管成分的非酶法。通过离心分离出基质血管成分,并使用流式细胞术检测、细胞培养和分化对分离出的细胞的特性和数量进行了测试。使用机械方法分离出了超过91%的活MSCs。这些细胞保留了分化为骨细胞、脂肪细胞和软骨细胞的能力。所提出的方法简单,无需特殊设备,并且能大量产生有活力的干细胞群体。这些细胞可以很容易地用于多种手术(骨科、牙科、瘘管等),使“一期”手术成为可能,从而证明了它们对患者和医疗保健系统的益处。
