文题释义:
肌血管内皮细胞:
位于血管壁,共表达肌肉干细胞和血管内皮细胞的标记(CD56+CD34+CD144+CD45-),这种血管源性肌肉干细胞被命名为肌血管内皮细胞。近年来越来越多的研究显示,肌血管内皮细胞与间充质干细胞存在相似性,同样具有多能性,有向多个细胞系分化的能力,如成骨细胞系、成软骨细胞系、成脂肪细胞系以及成肌细胞系。
肌血管外膜细胞:位于大、中、小以及毛细血管外壁周围,是血管周微环境重要核心组成成分,可以为其他细胞的生长繁殖提供支持作用,这种细胞可以通过细胞表面标记物(CD146+CD45-CD34-CD144-CD56-)被多参数流式细胞仪分选出来。近年来越来越多的研究显示,间充质干细胞来源于血管外膜细胞,肌血管外膜细胞是一类具有良好前景的间充质干细胞前体源性细胞。
多参数流式细胞分选术:运用不同荧光标记的多种抗体组合对细胞表面或胞内抗原的表达情况进行测量,同时运用流式细胞分选仪,以高能量激光照射高速流动状态下被荧光色素染色的单细胞或微粒,测量其产生的散射光和发射荧光的强度,从而进行分选的一门技术。

 

摘要
背景:
目前分离骨骼肌源性干细胞广泛应用的方法是差速贴壁培养法,而运用多参数流式细胞术分选人骨骼肌源性干细胞的研究较为少见。
目的:探索利用多参数流式细胞分选术从人体骨骼肌组织中分选高纯度肌源性血管内皮细胞和血管外膜细胞的方法。 
方法:收集人体骨骼肌组织,用胶原酶(Ⅰ型和Ⅳ型)及分散酶消化、获得单个核细胞,通过多参数流式细胞分选术分选表型为CD56+CD34+CD144+CD45-的肌血管内皮细胞和表型为CD146+CD45-CD34-CD144-CD56-的肌血管外膜细胞。
结果与结论:①利用多参数流式细胞分选术分选肌血管内皮细胞和肌血管外膜细胞各14例,肌血管内皮细胞在人骨骼肌单个核细胞中占(0.04±0.01)%,肌血管外膜细胞在人骨骼肌单个核细胞中占(0.30±0.07)%;②将新分选的细胞经过流式细胞仪回测后,肌血管内皮细胞纯度达到(96.8±1.16)%,肌血管外膜细胞纯度达到(92.50±0.50)%,锥虫蓝染色检测肌血管内皮细胞存活率达到(95.58±1.10)%,肌血管外膜细胞存活率达到(95.15±0.67)%;③肌血管内皮细胞和肌血管外膜细胞均能在体外诱导分化为成骨细胞和脂肪细胞,表明二者具有良好的多向分化能力;④实验建立了利用多参数流式细胞分选术分选肌血管内皮细胞和肌血管外膜细胞的有效方法,经过分选所得的肌血管内皮细胞和肌血管外膜细胞纯度高、活性良好。

Abstract:

BACKGROUND: At present, the preplate method is widely used for the separation of skeletal muscle-derived stem/progenitor cells. However, little is reported on the sorting of human skeletal muscle-derived stem/progenitor cells using multiparameter fluorescence-activated cell sorting (MP-FACS).
OBJECTIVE: To explore the method of sorting high-purity myoendothelial cells and perivascular stem cells from human skeletal muscle tissues by MP-FACS.
METHODS: Human skeletal muscle tissue was collected and digested with collagenase (type I and type IV) and dispase, to collect mononuclear cells. Myoendothelial cells with phenotype (CD56+CD34+CD144+CD45-) and perivascular stem cells with phenotype (CD146+CD45-CD34-CD144-CD56-) were sorted by MP-FACS.
RESULTS AND CONCLUSION: Fourteen samples of MECs and PSCs were sorted by MP-FACS. Myoendothelial cells and perivascular stem cells accounted for (0.04±0.01)% and (0.30±0.07)% in human skeletal muscle mononuclear cells, respectively. After the freshly sorted cells were re-analyzed by flow cytometry, the purity of myoendothelial cells and perivascular stem cells was up to (96.80±1.16)% and (92.50±0.50)%, respectively, and the survival rate of myoendothelial cells and perivascular stem cells reached (95.58±1.10)% and (95.15±0.67)%, respectively. After primary culture, myoendothelial cells and perivascular stem cells grew well, and furthermore, they could be successfully induced to differentiate into osteoblasts and adipocytes in vitro, respectively, indicating that myoendothelial cells and perivascular stem cells have good multi-differentiation ability. To conclude, the myoendothelial cells and perivascular stem cells obtained by MP-FACS have high purity and good activity.
