CHO cells are the top choice for making Biopharmaceutical Breakthroughs recombinant proteins and therapeutic antibodies in biopharmaceuticals. These cells, which come from Chinese hamster ovaries, are crucial in creating life-saving medicines. Let’s explore why CHO cells are so important and how they’re changing healthcare.
Key Points
- CHO cells are the gold standard for producing recombinant proteins and therapeutic antibodies
- They account for 70% of recombinant protein production in the biopharmaceutical industry
- CHO cells offer high productivity, adaptability to large-scale manufacturing, and genetic stability
- They are approved by global regulatory agencies for producing biologics
- The global biologics market using CHO cells was valued at USD 461.74 billion in 2022
What Are CHO Cells?
CHO cells, or Chinese Hamster Ovary cells, were first found in 1956 by scientist Theodore Puck. These cells quickly became popular with researchers because of their special qualities. CHO cells are strong, adaptable, and can be easily changed to make lots of proteins. They stay genetically stable, which makes them perfect for making consistent, high-quality biologics over long periods.
Think of CHO cells like tiny factories in a lab. Scientists can program these cells to make specific proteins our bodies need to fight diseases. It’s like having a custom workshop that can create exactly what doctors order! These versatile cells can grow in large bioreactors, allowing for industrial-scale production of therapeutic proteins. They’re especially good at making proteins that are very similar to human proteins, which is important for creating effective medicines.
Why CHO Cells Are the Superheroes of Biopharmaceuticals
CHO cells have several superpowers that make them perfect for making medicines:
- High Productivity: CHO cells can make a lot of protein quickly, which means more medicine can be produced in less time. This is really important for making enough medicine for people all over the world, especially for long-term illnesses and new health problems that pop up.
- Human-like Proteins: The proteins made by CHO cells are very similar to human proteins, which means our bodies accept them more easily. This makes the medicines work better and be safer for people to use.
- Safe and Reliable: CHO cells have been used for many years, so scientists know they’re safe and can trust them to make good quality medicines every time. Lots of health authorities around the world have approved using CHO cells to make medicines.
- Adaptable: These cells can grow in different conditions, making them flexible for various types of drug production. They can be grown in different ways and in different types of nutrient mixtures, which helps scientists make the best medicines possible.
Because of these amazing qualities, CHO cells are used to make about 70% of all protein-based medicines today. That’s a lot of life-saving drugs! From antibodies that fight cancer to proteins that help with blood clotting, CHO cells are really important in making modern medicines.

CHO Cells in Action: Making Medicines
Let’s look at how CHO cells help create important medicines:
- Antibodies: CHO cells are great at making antibodies, which are proteins that help our immune system fight diseases like cancer and autoimmune disorders. These include special antibodies for targeted cancer therapies, like trastuzumab for breast cancer and rituximab for certain types of lymphoma.
- Hormones: They can produce hormones like insulin for diabetes treatment, as well as growth hormones for various gland problems. The ability of CHO cells to properly fold and modify these complex proteins is crucial for making sure they work correctly in the body.
- Blood Factors: CHO cells make proteins that help blood clot, which is crucial for people with bleeding disorders. For example, they’re used to produce a protein called Factor VIII for people with hemophilia A, which helps them live much better lives.
Scientists use special tools like CRISPR to edit CHO cells’ genes, making them even better at producing these vital proteins. It’s like upgrading a computer to run faster and do more complex tasks! These genetic changes can help the cells make more protein, improve the quality of the protein, or even add new features to the medicines they produce. CHO cells are great for this kind of work because they can easily accept these genetic changes, which helps scientists develop new and better medicines.

Challenges and Future of CHO Cells
While CHO cells are amazing, they’re not perfect. Scientists are always working to make them even better:
- Improving Efficiency: Researchers are finding ways to make CHO cells produce more protein with less waste. This includes making their living conditions better, giving them better food, and using advanced containers to grow them in.
- Enhancing Quality: Work is being done to ensure the proteins made by CHO cells are even more like human proteins. This involves changing CHO cells so they can make proteins that are even more similar to what our bodies naturally make, which can help the medicines work better and be safer.
- Reducing Costs: Making medicines with CHO cells can be expensive, so scientists are trying to make the process cheaper. This includes finding better ways to clean the proteins, making cells that can produce for longer, and looking for cheaper food for the cells.
The future of CHO cells is exciting! New technologies like artificial intelligence are being used to design better CHO cells. These improved cells could help create new types of medicines and make current treatments more affordable for everyone. Computer programs are being used to predict the best ways to grow CHO cells and make medicines, which could really change how we develop and make biopharmaceuticals.
