文题释义:
骨膜:是骨表面除关节外所被覆的坚固的结缔组织包膜。在骨端和肌腱附着部位,非常致密地附着在骨上。其他部位的骨膜厚,容易从骨上剥离。
细胞分离技术:包括离心技术、流式细胞术和细胞电泳。离心是研究如细胞核、线粒体、高尔基体、溶酶体和微体,以及各种大分子基本手段。流式细胞术是对单个细胞进行快速定量分析与分选的一门技术。细胞电泳是指在一定pH值下细胞表面带有净的正或负电荷,能在外加电场的作用下发生泳动。

 

摘要
背景:
近年来,骨膜作为细胞治疗的种子细胞来源,因其自身的优越性而备受关注。
目的:探讨兔骨膜细胞分离培养的最佳方法及其生物学特性。
方法:无菌条件下取出兔胫骨内侧面骨膜,以Ⅱ型胶原酶消化结合组织块贴壁法分离培养兔骨膜细胞,置于DMEM/F12完全培养基培养。倒置显微镜观察细胞形态;CCK-8法检测骨膜细胞增殖活性,绘制细胞生长曲线图;流式细胞仪检测细胞表型CD90、CD105;成骨诱导培养基诱导骨膜细胞成骨分化,2周后茜素红染色检测钙结节沉积;成脂诱导培养基诱导骨膜细胞成脂分化,2周后油红O染色检测脂滴颗粒。
结果与结论:①Ⅱ型胶原酶消化结合组织块贴壁法原代培养耗时短,提高了组织块成活率;Ⅱ型胶原酶消化结合组织块贴壁法获得的骨膜细胞纯度较高,增殖能力强,呈梭形旋涡状或平形状生长,茜素红染色、油红O染色证实骨膜细胞具有多向分化潜能;②结果表明,Ⅱ型胶原酶消化结合组织块贴壁法能够在较短时间内获得高纯度的骨膜细胞,且增殖能力强,细胞具有多向分化能力。

Abstract:

BACKGROUND: Periosteum is considered as a source of seed cells for cell therapy due to its biological features.
OBJECTIVE: To seek the optimal way to isolate and culture rabbit periosteal cells and identify their biological features.
METHODS: Rabbit periosteum on facies medialis tibiae was taken out under aseptic conditions. Periosteal cells isolated through the digestion of type II collagenase with the explants culture method were cultured in DMEM/F12 complete medium. Cell ultrastructure was observed under an inverted microscope. Periosteal cell proliferation was determined by cell counting kit-8 assay. Cell surface antigens CD90 and CD105 were determined using flow cytometry. Osteogenic and lipogenic induction mediums were applied to induce periosteal cells to differentiate into osteocytes and adipocytes, respectively. After 2 weeks of induction, cells were harvested for alizarin red staining and oil red O staining to assay the calcium nodules and lipid droplet.
RESULTS AND CONCLUSION: The digestion of type II collagenase with the explants culture method shortened the period of primary cells culture and enhanced the survival rate, which caused higher purity and stronger reproductive activity of harvested periosteal cells. Primary cultured periosteal cells grew in form of spindle spiral or parallel. Alizarin red and Oil red O staining verified the multi-directional differentiation potentiality of periosteal cells. These findings suggest that the periosteal cells with high purity, strong reproductive activity, and multi-directional differentiation potentiality can be harvested in short time using digestion of type II collagenase with the explants culture method.
