Understanding VERO Cells
VERO cells come from the kidney cells of African green monkeys. Scientists first isolated them in 1962 in Japan. These cells are special because they can divide many times in a lab, which is called immortalization. This makes them great for long-term studies and making large amounts of vaccines.
VERO cells are used to make vaccines for diseases like polio, rabies, and flu. They can be infected by many different viruses, which helps scientists study how viruses work and develop treatments. VERO cells are also important for studying new viruses that appear. VERO cells from Cytion are carefully grown and tested to make sure they’re pure and healthy for researchers to use in their important work on viruses and vaccines.

Maintaining VERO Cell Line Integrity
Keeping VERO cells healthy is very important for making sure research results are reliable and can be repeated. The health and purity of these cells directly affect the quality of vaccines made and the accuracy of virus studies. Here are some important things to consider and best practices for keeping VERO cells healthy:
1. Use clean techniques: Always work in a clean area, use clean tools and materials, and follow proper hand washing and protective equipment rules. Regularly clean the area where you work with cells to prevent contamination.
2. Choose the right food for cells: VERO cells need specific nutrients to grow well. They usually grow in special liquids called DMEM or MEM, with added ingredients like fetal bovine serum, L-glutamine, and antibiotics. It’s important to use high-quality ingredients and prepare the cell food correctly.
3. Watch how cells grow: Regularly look at the cells under a microscope to check if they’re healthy and growing normally. Keep detailed records of how the cells look, how fast they grow, and any changes you notice.
4. Don’t let cells get too crowded: Keep the right number of cells in each container. When about 80% of the space is filled with cells, it’s time to split them into new containers. This helps the cells stay healthy and grow well.
5. Test for contamination: Regularly check for things that could harm the cells, like bacteria or fungi. Use special tests to look for these contaminants. Also, check for a type of contamination called mycoplasma, which can change how cells behave without showing obvious signs.
Jurkat Cells in Immunology Research
While VERO cells are important for studying viruses, Jurkat cells are just as important for studying the immune system. Jurkat cells come from human T cells, which are a key part of our body’s defense against diseases. These cells were first taken from the blood of a 14-year-old boy with a type of blood cancer in the 1970s. Since then, they’ve become very important for studying how the immune system works and for researching blood cancers.
Jurkat cells are valuable because they act like normal T cells but are easier to grow in a lab. They have many of the same parts on their surface and inside as regular T cells. This makes them great for studying how T cells work, how they make important substances called cytokines, and how they die. Researchers use Jurkat cells to study: 1. How T cells send signals inside themselves 2. How T cells get activated and change 3. How cytokines are made and controlled 4. How cells survive or die 5. Testing new drugs that affect the immune system 6. How genes related to the immune system work What we learn from Jurkat cells has helped create new treatments for autoimmune diseases, improve cancer treatments that use the immune system, and understand how HIV infects T cells. Cytion makes sure their Jurkat cells are high-quality and work properly, so researchers can trust them for their important studies on the immune system.
CHO Cells: Powerhouses of Protein Production
CHO cells, which stands for Chinese Hamster Ovary cells, have changed how we make medicines. They were first isolated in 1957 and have become the go-to cells for making special proteins used as medicines. CHO cells are great for making things like antibodies, hormones, and enzymes that we use to treat diseases. Here’s why CHO cells are so good at this job:
1. They can modify proteins: CHO cells can add complex sugar molecules to proteins in a way that’s similar to human cells. This is important because it helps the medicines work better and be safer for people to use. 2. They make a lot of protein: These cells can produce large amounts of the proteins we need for medicines. Some special CHO cells can make grams of protein in just a liter of liquid. 3. They can grow in different conditions: CHO cells can adapt to grow floating in liquid and in special food that doesn’t need animal products. This makes it easier to grow them in large amounts. 4. They’re genetically stable: CHO cells keep making the same proteins consistently over many generations. This is important for making medicines that are the same every time. 5. They’re safe: CHO cells have been used to make medicines for a long time, and we know they’re safe to use. CHO cells are also useful for basic research, studying how toxic things are, and looking at how drugs are processed in the body. Cytion offers different types of CHO cells, including some that are specially made to produce specific proteins. This helps both scientists in universities and companies that make medicines.

MDA-MB-231 cells are very important for studying breast cancer. They help us understand a type of breast cancer called triple-negative breast cancer, which is hard to treat. These cells were taken from a 51-year-old woman who had breast cancer that had spread to other parts of her body. MDA-MB-231 cells have several features that make them useful for cancer researchers:
1. They’re triple-negative: This means they don’t have three important receptors that some breast cancer treatments target. This makes them similar to triple-negative breast cancers that are hard to treat. 2. They can spread easily: These cells can move and invade other areas, which helps scientists study how cancer spreads and how to stop it. 3. They have genetic changes: MDA-MB-231 cells have changes in genes that are often changed in breast cancer. This makes them good for testing new treatments. 4. They help form blood vessels: They make substances that help new blood vessels grow, which is important for studying how tumors get blood supply and how to stop it. 5. They interact with the immune system: These cells can be used to study how cancer cells and immune cells interact, which is important for developing new treatments that use the immune system to fight cancer. Scientists use MDA-MB-231 cells to:
- Study how cancer cells spread to other parts of the body
- Test new cancer treatments, especially for triple-negative breast cancer
