To understand why HepG2 cells are special, it helps to compare them with other cells scientists use. This shows why HepG2 cells are often chosen for liver research.

HepG2 vs. HeLa Cells

While HeLa cells are famous and used in many types of research, HepG2 cells are made specially for studying the liver. HeLa cells are used in lots of different studies, but they don’t have the liver-specific functions that make HepG2 cells so useful for liver research. HepG2 cells have many genes and proteins that are specific to the liver, making them better for studying how drugs affect the liver and if they might be harmful.

HepG2 vs. HEK293 Cells

HEK293 cells are often used to study genes and make proteins. However, HepG2 cells are better at showing how the liver works. While HEK293 cells are great for making proteins in general, HepG2 cells are better for studying how the liver processes drugs and if they might be toxic. HepG2 cells have many of the enzymes that break down drugs, which is important when making new medicines.

HepG2 vs. Jurkat Cells

Jurkat cells are mainly used to study the immune system and a type of blood cancer. They’re good for learning about how T-cells in the immune system work. On the other hand, HepG2 cells are used to study liver functions, which makes them the best choice for liver research and studying how drugs are processed by the body. While Jurkat cells help us understand the immune system, HepG2 cells help us learn about things the liver does, like making bile and processing fats.

HepG2 vs. CHO Cells

CHO cells are used a lot to make proteins for medicines. HepG2 cells, however, are better for studying how drugs affect the liver and for learning about liver diseases. They give scientists a special tool for liver research. While CHO cells are great for making proteins that can be used as medicines, HepG2 cells help us understand how the liver might process these proteins.

Toxicology Studies

Scientists use HepG2 cells to see how drugs and chemicals affect the liver. These cells help them find substances that might be harmful and understand how they impact liver health. HepG2 cells have many of the enzymes that break down drugs, making them great for checking if new compounds might hurt the liver. This is really important when making new medicines, as it helps get rid of dangerous substances before they’re tested on people.

Drug Metabolism Research

HepG2 cells are crucial for studying how the liver processes different drugs. This information is vital for making safe and effective medicines. Researchers use these cells to investigate how various compounds are broken down, which helps predict how drugs might interact with each other and what side effects they might have. By understanding how drugs are processed in HepG2 cells, scientists can figure out the best dosages and make drugs work better with fewer side effects.

Disease Modeling

Scientists use HepG2 cells to study liver diseases like hepatitis and fatty liver disease. These cells help them understand how diseases work and test possible treatments. By changing HepG2 cells to act like they have certain diseases, researchers can study what’s happening at a molecular level in liver problems and test new medicines. This has been especially helpful in studying viral hepatitis, where HepG2 cells can be infected with hepatitis viruses to see how the virus grows and how cells respond.

Cancer Research

Since HepG2 cells come from liver cancer, they’re valuable for studying liver cancer and developing new cancer treatments. They allow researchers to investigate how liver cancer grows and to test new anti-cancer drugs. HepG2 cells can be used to study how cancer cells use energy, how they multiply, and how they respond to different treatments, which can lead to better therapies for people with liver cancer.

Good Things About Using HepG2 Cells

HepG2 cells have several benefits for researchers, which is why they’re often chosen for liver studies:

Key Points About HepG2 Cells

• They’re a good alternative to using actual human liver cells
• HepG2 cells have some limitations compared to normal liver cells
• Researchers need to know the strengths and weaknesses of HepG2 cells

Easy to grow and take care of: HepG2 cells are pretty simple to grow and maintain in labs. They stay stable for a long time and keep their liver-specific features. This stability makes them great for long studies and helps make experiments more consistent.

Good for testing lots of things quickly: The strong nature of HepG2 cells makes them excellent for testing many compounds quickly and efficiently. This makes these cells valuable in discovering new drugs and studying toxicology.

Reliable model for human liver function: While not perfect, HepG2 cells keep many functions of human liver cells. They have many liver-specific genes and proteins, making them a valuable model for studying various aspects of liver biology, including how drugs are processed and if they might be toxic.

Better alternative to primary liver cells: Using HepG2 cells reduces the need for actual human liver cells, which are often hard to get and raise ethical concerns. This makes HepG2 cells easier to access and more ethically sound for many research applications.

Consistent and repeatable results: HepG2 cell cultures are more uniform, which allows for more consistent and repeatable results compared to primary liver cells, which can vary a lot between donors. This consistency is especially valuable in drug screening and toxicology studies where reliable, repeatable results are crucial.

Challenges and Things to Consider

While HepG2 cells are very useful, they do have some limitations that researchers need to think about when designing experiments and looking at results:

• Less metabolic ability compared to real liver cells: HepG2 cells have fewer of some key metabolic enzymes compared to primary liver cells. This can lead to underestimating metabolic activity for certain compounds, especially those that need a lot of processing in the body.
• May not fully represent all aspects of normal liver function: Since HepG2 cells come from cancer, they might not accurately show all the functions of healthy liver cells. Some liver-specific functions might be changed or missing in these cells.
• Need careful interpretation of results when thinking about the whole liver: While HepG2 cells provide valuable insights, researchers must be careful about applying results to whole-liver function. The complex interactions within the liver may not be fully captured in this single-cell type model.

Researchers should be aware of these limitations and consider using other methods or primary liver cells when necessary for comprehensive studies. It’s often good to check key findings from HepG2 cells using other models or studies in living organisms to ensure the results are relevant and applicable.

Best Ways to Grow HepG2 Cells

To get the best results from HepG2 cells and make sure the results are reliable and repeatable, researchers should follow these best practices:
