Abstract

Abstract:

CHO cells comprise a variety of lineages including CHO-K1， CHO-DG44 and CHO-S， which have been widely used in the industrial production of biological drugs. All CHO cell lines share a common ancestor， however， during the process of cell passage cultivation， cell domesticated， and preservation by different laboratories or companies， substantial genetic heterogeneity among them has been produced， that showed great differences in cell growth state， antibody titer， glycosylation and other product quality attributes. This article reviewed the difference in chromosome， growing status and expression， and glycoform in different sources of CHO host cells， which was expected to be helpful in host cell selection during antibody drug research and development process.

Key words: CHO cells, monoclonal antibody, antibody titer, glycosylation

摘要：

CHO细胞作为宿主细胞广泛应用于生物药工业化生产中。其中，CHO-K1、CHO-DG44和CHO-S是最常见的3种亚型。虽然这些亚型是从共同的原始CHO细胞分离出来的，但在不同的实验室或生物医药公司、研究人员、培养基或培养方式下连续传代、驯化和保存，使得CHO细胞积累了大量变异，导致宿主细胞应用于抗体药生产时会在细胞生长状态、抗体表达量及以糖型为代表的质量属性方面表现出较大差异。综述了CHO细胞不同亚型的染色体差异、生长状态、表达差异以及糖型差异，以期为抗体药物研发中宿主细胞的选择提供参考。

关键词: CHO细胞, 抗体, 表达量, 糖型
