Chinese Hamster Ovary (CHO) cells are one of the most widely used mammalian cell lines for recombinant protein production, particularly in the biopharmaceutical industry. The choice of CHO cells is due to their ability to grow in suspension, adapt to serum-free conditions, and produce high yields of complex, post-translationally modified proteins that are similar to human proteins.
CHO recombinant expression systems are crucial for producing a wide range of biopharmaceuticals, including:
1. Monoclonal Antibodies (mAbs)
2. Recombinant Hormones and Enzymes
3. Vaccines
Despite significant advancements, CHO systems still face challenges, such as the complexity of scaling up processes and the need for further improvements in glycosylation fidelity. Future directions include the development of fully humanized CHO cells, further enhancements in gene editing technologies, and the integration of artificial intelligence to optimize production processes.
