Cryopreservation of Cells: Best Practices for Long-Term Storage
Cell cryopreservation is a really important technique in science. It lets scientists keep living cells super cold, so they stay alive and usable for future experiments. This helps keep cell lines consistent, saves money, and makes sure research results are reliable. Let’s learn about how scientists freeze cells and store them for a long time.
Cryopreservation has made a big difference in biomedical research. It allows scientists to keep valuable cell lines and primary cells for long periods. This helps make experiments more repeatable and allows for long-term studies.
| Key Takeaways |
|
What is Cell Cryopreservation?
Cryopreservation is freezing biological stuff, like cells, at very low temperatures. This slows down what’s happening inside cells and stops damage that would normally happen over time. When done right, frozen cells can be stored for years and still work when thawed out. The process carefully balances taking water out of cells to stop ice from forming inside while keeping the cell’s structure and function intact.
The main goal is to protect cells from ice crystals, which can hurt or kill them. To do this, scientists use special chemicals called cryoprotectants and carefully control how cells freeze and thaw. These chemicals replace water in the cell, reduce ice crystal formation, and protect cell parts from freeze-thaw damage. The whole process needs to be really precise to make sure cells are still good when they’re thawed.
Key Parts of Successful Cryopreservation
- Cryoprotective Agents (CPAs)
Cryoprotective agents are chemicals that help protect cells during freezing. They work by reducing ice crystal formation and preventing cells from drying out too much. The most common CPA used is dimethyl sulfoxide (DMSO). DMSO works well because it can quickly get into cells and isn’t too toxic at the amounts used for freezing. Other CPAs include glycerol, ethylene glycol, and different sugars, each with specific benefits for different types of cells.

- Controlled Cooling Rate
How fast cells cool down is really important for successful cryopreservation. Usually, a slow, controlled cooling rate of about -1°C to -3°C per minute is best. This lets water move out of the cells slowly, which reduces the risk of ice crystals forming inside. The controlled cooling rate is crucial because it allows for the best balance between cells drying out and ice forming inside them. If cells cool too fast, ice can form inside. If they cool too slowly, they can dry out too much and get stressed.
- Proper Storage Temperature
Once frozen, cells need to be kept at ultra-low temperatures, usually below -135°C. This is often done using liquid nitrogen storage tanks. At these temperatures, all biological processes basically stop, which prevents cells from breaking down and keeps them viable for a long time. It’s really important to keep the storage temperature steady, as changes can lead to ice recrystallizing and damaging cells. Proper monitoring and maintenance of storage systems are essential for long-term preservation success.
Best Ways to Freeze Cells
- Prepare Healthy Cells
Start with cells that are in good condition and growing well. Cells should be in their growing phase and more than 90% should be alive. Using healthy cells helps more of them survive the freezing and thawing processes. It’s important not to freeze cells that are stressed, contaminated, or getting old, as these factors can really reduce how well they survive and work after thawing.
- Use the Right Freezing Liquid
The freezing liquid should have the right cryoprotectant (usually 5-10% DMSO) and might also include serum or other protective proteins. The mix of the freezing liquid can be made just right for different cell types to help as many cells as possible survive after thawing. Some cell types might do better with growth factors or other supplements added to the freezing liquid. It’s important to make fresh freezing liquid each time you freeze cells to make sure they’re protected as well as possible.
- Cool Cells Slowly and Steadily
Use a special container that controls the cooling rate to get the best cooling rate of -1°C to -3°C per minute. This can be done with special equipment or simpler cooling devices like Mr. Frosty containers. Steady cooling rates are really important to let cells dry out properly and prevent ice from forming inside them. Some advanced freezing methods might use multi-step cooling processes for especially sensitive cell types.
- Move to Long-Term Storage Quickly
Once cells reach -80°C, move them quickly to liquid nitrogen storage for long-term keeping. This move should be done fast to prevent any warming of the samples, which could lead to ice recrystallizing and damaging cells. Properly labeling and organizing stored samples is crucial for easily finding and tracking frozen cells.
- Thaw Cells Rapidly
When it’s time to use the cells, thaw them quickly in a 37°C water bath. This fast thawing helps prevent ice crystals from forming as the cells warm up. Quickly removing the cryoprotectants and slowly putting cells back into normal growth liquid are important steps to minimize shock to the cells and help as many survive as possible. It’s a good idea to check how many cells are alive and how well they’re working shortly after thawing to make sure the preserved cells are still good quality.
Key Cell Lines Used in Research
Several cell lines are commonly used in scientific research because of their special properties and uses. Let’s look at some of the most important ones:

The ability to preserve induced pluripotent stem cells (iPSCs) and their differentiated progeny is particularly valuable for modeling diseases and screening drugs.
Challenges and Ethical Considerations
While freezing cells offers many benefits, it also comes with challenges and ethical considerations:
- Contamination Risks
Proper clean techniques and regular testing are essential to prevent bacterial, fungal, or mycoplasma contamination of cell cultures. Storing cells for a long time increases the risk of introducing contaminants during handling and storage. Using strict quality control measures and growing cells without antibiotics when possible can help reduce these risks. Regularly checking cryopreserved stocks for contaminants is crucial to maintain the integrity of cell banks.
- Genetic Drift
Over time and after many passages, cell lines can experience genetic changes. Regularly checking cell lines to make sure they’re still the same is important to ensure their identity and characteristics remain consistent. Genetic drift can lead to changes in how cells look and respond to experimental treatments, potentially messing up research results. Limiting how many times cells are passaged and periodically going back to early passage stocks can help maintain genetic stability.
- Ethical Use of Human-Derived Cell Lines
Using cell lines that come from humans, especially those obtained without proper permission (like the original HeLa cells), raises ethical concerns. It’s important to use cell lines ethically and properly acknowledge where they came from. Modern bioethics guidelines stress the importance of informed consent and protecting the privacy of people who donate biological materials. Researchers should be aware of the ethical implications of using certain cell lines and consider alternatives when appropriate.
