摘要:

文题释义:
生物反应器:通过搅拌或灌流使载体悬浮在罐体内的培养基中,细胞通过接触培养基获取增殖所需的营养成分并在载体表面增殖,该缸体与搅拌或悬浮系统及其它辅助部件即为生物反应器。生物反应器通常可容纳超过1 L培养基,是工业级细胞培养所需的装置。
非多孔状细胞培养微载体:为粒径在100-400 µm的微珠,具有适宜细胞贴壁及增殖的表面条件,适配搅拌式生物反器。通常非多孔状细胞培养微载体在使用生物反应器时的细胞培养浓度为109-1010 L-1。

背景:搅拌式生物反应器中的关键耗材为非多孔微载体,它适用于贴壁细胞培养,对病毒、重组蛋白、干细胞生产具有重大意义。
目的:从细胞-微载体黏附的有利条件出发,总结非多孔微载体的材料选取及制备方法。 
方法:应用计算机检索中国知网、PubMed、Web of Science数据库,以“细胞培养,贴壁细胞,微载体,纤连蛋白,生物反应器,微球制备”为中文检索词,以“cell adhesion,microcarrier,bioreactor,dextran,cell-matrix interaction,suspension culture”为英文检索词,文献检索时限限定为1967-2025年,根据纳入和排除标准进行筛选,最终纳入52篇文献进行汇总分析。
结果与结论:非多孔微载体适用于细胞浓度为109-1010 L-1的贴壁细胞培养。由于细胞贴壁的需求,非多孔微载体需提供适当的表面正电荷或整合素结合位点。葡聚糖、聚苯乙烯、胶原材质的非多孔微载体已经商品化,能够广泛支持多种细胞的大规模培养。已有壳聚糖、纤维素材质的非多孔微载体进行大规模细胞培养的报道,然而这些新材质的非多孔微载体并未商业化。葡聚糖与聚苯乙烯微载体的商业化时间长,制备方法分别为交联法与聚合法,制备技术成熟。胶原、纤维素微载体多用交联法制备,壳聚糖微载体的制备方法包括交联法与相反转法。

Abstract: BACKGROUND: The key consumable item in stirred-tank bioreactors is non-porous microcarriers, which are suitable for adherent cell culture and play a significant role in the fabrication of viruses, recombinant proteins, and stem cells.
OBJECTIVE: To summarize the material selection and manufacturing methods of non-porous microcarriers based on the favorable conditions for cell-microcarrier adhesion. 
METHODS: A computerized search of CNKI, PubMed, and Web of Science databases was performed with the search terms “cell cultivation, adherent cells, microcarrier, fibronectin, bioreactor, microsphere preparation” in Chinese and “cell adhesion, microcarrier, bioreactor, dextran, cell-matrix interaction, suspension culture” in English. The search time limit was from 1967 to 2025. After screening according to the inclusion and exclusion criteria, 52 articles were finally included for summary analysis.
RESULTS AND CONCLUSION: Non-porous microcarriers are suitable for adherent cell culture at a density of 109-1010 cells/L. Due to the requirements for cell adhesion, non-porous microcarriers need to provide appropriate surface positive charge or integrin binding sites. Non-porous microcarriers made of dextran, polystyrene, and collagen have been commercialized and can widely support large-scale culture of various cell types. While reports exist of large-scale cell culture using non-porous microcarriers made of chitosan and cellulose, these new materials have not yet been commercialized. Dextran and polystyrene microcarriers have been commercialized for a long time, with mature preparation methods including cross-linking and polymerization, respectively. Collagen and cellulose microcarriers are mostly prepared using cross-linking methods, while chitosan microcarriers can be prepared using both cross-linking and phase inversion methods.
