Abstract: Abstract: In recent years, because of the advantages of proper folding, assembling and the modification of posttranslation for recombinant proteins, using mammalian cells to produce medical proteins has become an important part of biopharmaceutical industry. However, the yields of medical proteins in mammalian cells are still relatively low. Therefore, a hot research topic focuses on how to improve medical protein production in mammalian cells. In this review, we only summarized the recent achievements in methods for improving medical protein production in mammalian cells, including constructing high-level expression vector system, screening cell lines with stable and high expression, optimizing the transcription and translation, optimizing transient expression, improving culture biotechnology, and inhibiting cell apoptosis.
