摘要:

背景:脂肪组织消化后得到的血管基质部分是多种细胞的混合体,其中以克隆样生长的细胞组分可能是真正具有“干性”维持能力的脂肪间充质干细胞。

目的:分离、传代、培养脂肪组织血管基质部分中的克隆形成细胞,并检测其在动物模型中修复膝关节软骨的能力。
方法:培养新鲜分离得到的脂肪组织血管基质部分,挑选其中以克隆样生长的贴壁细胞,消化、传代、培养至第3代。通过手术建立骨关节炎兔模型,将第3代克隆形成细胞移植入模型兔关节腔,与未进行细胞移植治疗的模型兔进行比较,观察兔膝关节软骨的再生情况。
结果与结论:脂肪组织中血管基质部分细胞接种后第3天,贴壁细胞中出现克隆样生长的细胞集落,生长至第5天时,克隆样生长的细胞集落数和周围的单个细胞数均增加,传代至第3代时,仍然呈克隆样的集落生长,梭形形态。大体观察和MRI检查此类克隆形成细胞能在关节腔内帮助软骨修复,增加滑液分泌,同时有助于控制炎症,溃疡面积呈缩小趋势。实验结果有助于优化脂肪间充质干细胞的体外分离、培养体系,并为临床上治疗骨关节炎提供了新的思路。

Abstract:

BACKGROUND: Stromal vascular fraction digested from adipose tissue is a mixture of a variety of cells, and clone-like cell components may have the real ability to maintain the stemness of mesenchymal stem cells

OBJECTIVE: To separate, passage and culture colony-forming cells in the stromal vascular fraction of adipose tissue, and to test its ability to repair the knee cartilage in animal models.
METHODS: Stromal vascular fraction isolated from fresh adipose tissue was cultured to collect clone-like adherent cells that were subject to digestion and passage until the third generation. A rabbit model of osteoarthritis was established surgically, and the third generation of colony-forming cells were transplantated into the articular cavity of model rabbits. Model rabbits with no cell transplantation served as controls. Cartilage regeneration in the knee joint of model rabbits were observed and compared.
RESULTS AND CONCLUSION: At 3 days after transplantation of stromal vascular fraction cells, clone-like cell colonies appeared in adherent cells; at 5 days, the amount of clone-like cell colonies and surrounding single cells were both increased. At the passage 3, the clone-like cell colonies were also visible, which were fusiform in shape. Gross observation and MRI examination showed that these colony-forming cells could promote cartilage repair in the joint cavity, increase secretion of synovial fluid, and help to control inflammation and narrow ulceration area. Experimental findings are beneficial for optimizing the isolation and culture of adipose-derived mesenchymal stem cells and provide a new way for the clinical treatment of osteoarthritis.
