What Are HepG2 Cells?
HepG2 cells come from a liver cancer patient’s sample taken in 1975. They’ve become very important in liver research because they can do many things that normal liver cells do. HepG2 cells look like small liver cells and can perform many liver functions. This makes them great for studying how drugs affect the liver, liver toxicity, and different liver diseases.
Our HepG2 cell line is carefully maintained to meet high research standards. These cells have special features that make them very useful for liver studies. They can make many liver proteins and can change foreign substances, which is great for studying how drugs are processed in the body.
HepG2 Cells in Liver Toxicity Testing
HepG2 cells are really important for checking if drugs or chemicals might harm the liver. They help scientists understand:
- How drugs move through and are processed by the liver
- How drugs can hurt the liver
- How the body changes drugs
- Ways to test drugs without using as many animals
Our HepG2 cells are used a lot in toxicology research. They provide a reliable way to study how drugs affect the liver. Their consistent performance makes them ideal for predicting drug safety. Researchers can use these cells to test many compounds quickly, finding potentially harmful ones early in drug development. This saves time and money in pharmaceutical research.

Benefits of Using HepG2 Cells
Using our HepG2 cells in research has many important advantages. These benefits make them widely used in liver studies and drug development:
- Genetic stability: HepG2 cells stay the same over many generations, giving consistent results across experiments
- Cost-effective: They’re cheaper than using real human liver cells, allowing for larger studies
- Easy to grow: HepG2 cells are simpler to take care of than real liver cells
- Less animal testing: Using these cells helps reduce the need for animal experiments in early drug testing
- Long-term use: Unlike real liver cells, HepG2 cells can be kept growing for a long time, good for long-term studies
- Always available: As a cell line that keeps growing, HepG2 cells are always ready to use, unlike limited real liver cells
These factors make HepG2 cells a must-have tool for many researchers studying liver function, how drugs are processed, and liver toxicity.

Limits of HepG2 Cells
While HepG2 cells are very useful, it’s important to know their limits for proper use in research. These cells are different from real human liver cells in some ways:
- Metabolic capacity: HepG2 cells have fewer of certain enzymes important for processing drugs. This might lead to underestimating how some compounds are changed or detoxified.
- Gene expression: Some liver-specific genes work differently in HepG2 cells compared to real liver cells. This can affect how they respond to certain stimuli or drugs.
- Drug processing: Because they come from cancer cells, HepG2 cells might not handle all drugs the same way a healthy liver would. This could lead to differences in predicting toxicity or effectiveness.
- Long-term studies: While HepG2 cells can be kept longer than real liver cells, very long studies might still be tricky because the cells could change over time.
- Cancer origin: As cancer cells, HepG2 cells might behave differently from normal liver cells in some ways. This could affect certain types of studies, especially those about normal liver function.
Our team at Cytion provides full information to help researchers decide if HepG2 cells are right for their studies. We encourage careful consideration of these limits when planning experiments and looking at results. We also offer guidance on other approaches or cell models when needed.
