HepG2 cells are important for liver cancer research. These cells come from human liver tumor tissue and help scientists study how the liver works, how drugs are processed, and how toxic substances affect the body. Let’s learn about HepG2 cells, how they compare to other cells used in research, and why they’re useful for studying the liver.
Key Takeaways

What Are HepG2 Cells?
HepG2 cells come from a liver tumor of a 15-year-old boy. These cells have some special features:
- They have 50-60 chromosomes (more than normal cells)
- They have a normal TP53 gene, which helps protect cells
- They have changes in genes that make them live longer than normal cells
Scientists like using HepG2 cells because they can do many jobs that normal liver cells do. They’re easy to grow in the lab, which makes them popular for different kinds of studies. Their special genetic makeup helps researchers learn about how liver cancer develops and how it might be treated.
How HepG2 Cells Compare to Other Cell Types
HepG2 vs. HeLa Cells
HeLa cells were the first human cells that could grow forever in a lab. They come from cervical cancer. HepG2 cells are better for studying the liver because they can do more liver-specific jobs. For example, HepG2 cells make more proteins that are usually found in the liver, which helps scientists study how the liver processes drugs.
HepG2 vs. HEK293 Cells
HEK293 cells come from human kidney cells. While they’re good for making proteins and studying genes, HepG2 cells are better for liver research. HepG2 cells show how liver proteins interact and how the liver processes substances, which is really important for studying liver diseases and new medicines.
HepG2 vs. Jurkat Cells
Jurkat cells are immune system cells used to study how the body fights diseases. HepG2 cells are the best choice for liver studies because they have many liver enzymes that help break down drugs. This makes them really useful for testing new medicines and seeing how they might affect the liver.
HepG2 vs. CHO Cells
CHO cells come from hamster ovaries and are used to make medicines. HepG2 cells are better for studying human liver functions because they come from human liver cells. They help scientists understand how the human liver processes drugs and makes important substances, which is crucial when developing new medicines.
How Scientists Use HepG2 Cells
1. Studying Toxic Substances
Scientists use HepG2 cells to see if new drugs or chemicals might hurt the liver. These cells help predict if a substance could be dangerous to humans. Researchers can test many different compounds quickly using HepG2 cells, which is really helpful when developing new medicines.
2. Understanding How Drugs Are Processed
HepG2 cells help researchers see how the liver breaks down different substances. While they don’t have all the enzymes that real liver cells have, they’re still useful for studying how drugs interact and how the liver processes them. This information is important for making sure new medicines are safe and effective.
3. Modeling Liver Diseases
Scientists can use HepG2 cells to study liver diseases like hepatitis and fatty liver disease. They can change the cells to act like they have a disease, which helps researchers understand how these diseases work and test possible treatments. For example, they can make HepG2 cells store extra fat to study fatty liver disease.
4. Cancer Research
Since HepG2 cells come from a liver tumor, they’re great for studying liver cancer. Researchers use them to understand how liver cancer grows and to test new treatments. These cells help scientists learn about the changes that happen in liver cells that lead to cancer.
Why HepG2 Cells Are Useful
Key Advantages of HepG2 Cells
- Easy to grow and take care of in the lab
- Good for testing lots of substances quickly
- Provide a reliable way to study human liver function
- Don’t raise the ethical concerns that using real human liver cells do
- Can be grown for a long time without changing
Challenges with Using HepG2 Cells
While HepG2 cells are useful, they have some limitations:
- They don’t make as many enzymes as real liver cells
- They might not act exactly like normal liver cells in all situations
- They’re not the best for studying all aspects of how drugs are processed
Scientists are working on ways to make HepG2 cells even better. They’re trying to grow them in 3D shapes and change their genes to make them more like real liver cells. These improvements could make HepG2 cells even more useful for research.
Taking Care of HepG2 Cells
To keep HepG2 cells healthy for research, scientists need to:
- Use good quality food for the cells
- Make sure there aren’t too many or too few cells growing together
- Be gentle when moving or splitting the cells
- Keep the cells at the right temperature and in the right environment
- Check regularly to make sure the cells aren’t contaminated
Taking good care of the cells helps make sure the research results are reliable. It’s also important to use cells that haven’t been grown for too long, as they can change over time.
Conclusion
HepG2 cells are really important for liver cancer research. They help scientists study how drugs affect the liver, how toxic substances work, and how liver diseases develop. While they’re not perfect, they’re easy to use and stay consistent over time, which makes them great for many types of research.
These cells are helping scientists learn a lot about how the liver works and what goes wrong in liver diseases. As research methods get better, HepG2 cells will probably become even more useful, especially as scientists find ways to make them more like real liver cells.
If you’re doing liver research, HepG2 cells can be a big help. You can find high-quality HepG2 cells and other cell types at Cytion.com. Using the right cells and taking good care of them can help you make important discoveries about liver cancer and develop new treatments.
