摘要:

背景:肿瘤组织工程通过构建综合的培养模型,充分模拟肿瘤在体内生长的微环境,可以较好地研究肿瘤发生发展的动力学及相关治疗策略。
目的:综述肿瘤工程技术中的肿瘤细胞三维培养。
方法:以“tumor engineering; 3D culture; biological materials; dynamic”为关键词,检索PubMed数据库1992年1月至2013年3月相关文献,纳入有关肿瘤工程、肿瘤细胞三维培养、生物支架材料及肿瘤微环境的相关文章。
结果与结论:三维培养因其可再现组织细胞的体内生长情况,已成为研究肿瘤耐药性、侵袭性和肿瘤微环境的重要平台,在许多领域表现出逐步取代平面培养技术的趋势,为肿瘤研究提供了一个非常接近于体内真实情况的研究平台。近年来,随着肿瘤工程学的发展,多种新型高分子聚合材料被应用于肿瘤细胞的三维立体培养,三维培养技术逐渐成为肿瘤生物学领域研究的热点,其利用各种方法及材料使细胞呈空间立体方式生长,形成类似体内生长环境的生物支撑或基质,建立细胞间及细胞与胞外基质间的相互联系,并形成特定的类似组织样的三维空间结构。生物材料就是种子细胞生长的土壤,在肿瘤工程中起着替代细胞外基质或组织、器官的基质的作用。而随着三维细胞培养技术在肿瘤研究中的广泛应用,其已成为肿瘤耐药、血管形成、细胞间相互作用、信号转导、干细胞等方面研究不可或缺的有力工具。

Abstract:

BACKGROUND: The tumor tissue engineering can build an integrated culture model to fully simulate the in vivo microenvironment of tumor growth, which can be used to study tumor developmental dynamics and related treatment strategies.
OBJECTIVE: To review the three-dimensional culture of tumor cells using tumor engineering technology.
METHODS: PubMed database was retrieved for articles related to tumor engineering, three-dimensional culture of tumor cells, biological scaffold materials and tumor microenvironment published from January 1992 to March 2013.
RESULTS AND CONCLUSION: Three-dimensional culture, because of its reproducible tissue and cell growth in vivo, has become an important platform for study of tumor resistance, invasiveness and tumor microenvironment. The three-dimensional culture has showed a trend to gradually replace the flat culture technique in many fields, and provides a research platform which is very close to in vivo environment. In recent years, with the development of tumor engineering, a variety of new polymer materials have been used in the three-dimensional culture of tumor cells. Three-dimensional culture technology is becoming a hotspot in the field of tumor biology, in which, using a variety of methods and materials, the cells show a growth in the spatial manner to form a biological support or matrix similar to in vivo growth environment. Biomaterials have become the soil on which seed cells can grow well, and plays an alternative to the extracellular matrix or the matrix of tissues and organs in the tumor engineering. Therefore, the three-dimensional cell culture has been widely used in cancer research, which has become a powerful tool to tumor drug resistance, angiogenesis, cell-cell interaction, signal transduction, stem cells and other research.
