ABSTRACT
@#The productivity of cells per unit area determines the scale-up potential of the cell culture process,and the largescale application of the microcarrier system provides space for the high-yield culture of anchorage-dependent animal cells. The microcarrier animal cell culture technology is suitable for efficient production process development and optimized amplification. In recent years,microcarrier-based culture technology has been widely used in various types of animal cell culture to produce many important biological products such as vaccines,enzymes,hormones,antibodies,interferons and other probiotics. In this paper,the research progress of domestic and foreign microcarrier cell culture technology,the comparison of new microcarriers and traditional microcarriers and their applications were reviewed,so as to provide reference for the in-depth research and application of large-scale cell culture technology based on new microcarriers.
