The next events that catapulted CHO cells into prominence was a combination of FDA approval for bio-therapeutic protein production, the commercial production of animal origin free media developed specifically for a single cell type such as CD-CHO medium and the cells ability to grow in suspension. Xell’s scientists have more than 20 years of experience with cell culture and state-of-the-art culture media.

While CHO cell lines have conventionally been grown as attached cultures they will also grow in free suspension; this has allowed for simple scale up in stirred tank and airlift bioreactors. Cells that are cultured in suspension can be maintained in culture flasks that are not tissue-culture treated, but as the culture volume to surface area is increased beyond which adequate gas exchange is hindered (usually 0.2 – 0.5 mL/cm 2), the medium requires agitation. The next events that catapulted CHO cells into prominence was a combination of FDA approval for bio-therapeutic protein production, the commercial production of animal origin free media developed specifically for a single cell type such as CD-CHO medium and the cells ability to grow in suspension.
Many events occurred to bring CHO cells to the forefront in biotechnology. I know that CHO cells can be adapted for either adherent or suspension culture, depending on the desired application.

Culture should be 50 to 80% confluent to ensure that the cells are actively dividing. Since then, CHO cells have been a cell line of choice because of their rapid growth in suspension culture and high protein production. Having a very low chromosome number (2n=22) for a mammal, the Chinese hamster is also a good model for radiation cytogenetics and tissue culture. Subcultivation of CHO cells in suspension culture using the commercial serum-free medium EX-CELL™302, which contained an IGF-1 analog, supplemented with LPA resulted in gradually increasing specific growth rate comparable to the serum-containing medium and in almost the same high antibody production regardless of the number of generations.

in biotechnology for the production of compounds, and as model systems in fundamental research. Especially in medical research liquid cultures remain essential to facilitate the understanding and treatment of diseases. However, the heterogeneity of high cell density suspension cultures for therapeutic protein production remains unknown. Here, we illustrate the increasing heterogeneity in the cellular transcriptome of serum‐free adapted CHO K1 cells during high cell density suspension culture over time without concomitant changes in the genomic sequence. Despite stated advantages, the vast majority of biotherapeutics today are manufactured using suspension CHO cells grown in fed-batch culture (typically over a 14-day batch period). There are some biologic drugs manufactured using perfusion bioreactors including Factor VIII from Bayer, ReoPro and Remicade from Centocor, Campath from Sanofi and ReFacto from Pfizer.
