文题释义:
人多能干细胞:
是一类具有多向分化潜能的细胞,例如人胚胎干细胞和人诱导多能干细胞,它们具有体外自我更新和长期分化为人体内所有细胞类型的能力,是多种疾病治疗的首选种子细胞起源,具备良好的细胞治疗前景。
人多能干细胞三维培养:科学家通过研究体内支持人多能干细胞自我更新或分化微环境的组成,分析影响人多能干细胞贴壁、干性维持和分化的关键因素,从而在体外构建支持人多能干细胞自我更新或定向诱导分化的三维培养体系,并进行细胞培养。

 

摘要
背景:
人多能干细胞具有体外长期自我更新和分化为几乎所有体细胞类型的独特潜能,在细胞治疗、再生医学、药物筛选、毒理学测定、疾病建模和立体器官发生等领域有广泛的应用前景。传统体外二维培养方法难以获得大量的细胞,而三维培养技术为人多能干细胞的大规模生产开辟了一条新的途径。
目的:对目前人多能干细胞三维培养的研究进展作一综述。
方法:应用计算机检索PubMed和CNKI数据库2005年1月至今有关人多能干细胞三维培养的文章,英文检索词为“human pluripotent stem cells,three dimension culture,microcarrier,suspension culture,aggregates,hydrogel,microencapsulation,bioreactor system,pluripotency”,中文检索词为“多能干细胞,三维培养”,保留77篇文献进行分析。
结果与结论:细胞聚集体、微载体和水凝胶是目前实验室三维培养多能干细胞的主要形式。与二维培养相比,三维培养可更高效地扩增细胞,提高细胞产量,为人多能干细胞临床应用奠定了良好的基础。

Abstract:

BACKGROUND: Human pluripotent stem cells have the unique potential of long-term self-renewal and differentiation into almost all somatic cell types in vitro, and they are are promising candidates for cell treatment, regenerative medicine, drug screening, toxicology determination, disease modeling and stereo organogenesis. It is difficult using in vitro two-dimensional culture to obtain large quantities of cells, while three-dimensional culture provides a new way for large-scale expansion of human pluripotent stem cells. 
OBJECTIVE: To review the current research progress in the three-dimensional culture of human pluripotent stem cells.
METHODS: With the key words of “human pluripotent stem cells, three dimension culture, microcarrier, suspension culture, aggregates, hydrogel, microencapsulation, bioreactor system, pluripotency” in English and “pluripotent stem cells, three dimension culture” in Chinese, we performed a computer-based search in PubMed and CNKI databases respectively for relevant articles published from January 2005 to present. Finally, 77 eligible articles were included in result analysis.
RESULTS AND CONCLUSION: Currently, three culture modes, aggregates, microcarriers, and hydrogels, are mainly used for the three-dimensional culture of human pluripotent stem cells in the laboratory. Compared with two-dimensional culture, three-dimensional culture can expand cells and increase cell yield more efficiently, which lays a good foundation for the clinical application of human pluripotent stem cells.
