What is the Difference Between Mammalian and Microbial Cell Culture?
🆚 Go to Comparative Table 🆚The main difference between mammalian and microbial cell culture lies in the type of cells being cultured and their complexity. Here are some key differences between the two:
- Cell Type: Mammalian cell culture involves cells derived from mammals, while microbial cell culture involves the growth of microbial cells, such as bacteria or yeast.
- Cellular Complexity: Mammalian cells are eukaryotic cells, which means they are more complex than bacterial cells. Mammals consist of billions of individual cells in many organs and tissues, resulting in a lot of specialization among mammalian cells.
- Matrix Requirement: Mammalian cell cultures typically require a matrix to adhere, while microbial cells usually do not require a matrix.
- Growth Environment: Mammalian cells are grown in flasks or bioreactors, using a growth medium for the cell growth process. Microbial cells, on the other hand, can be grown in various types of media, depending on the specific microorganism.
- Expression Systems: Mammalian cell expression systems can produce more complex proteins with post-translational modifications, while bacterial expression systems are simpler and faster.
- Cost and Ease of Use: Microbial cell cultures are generally cheaper and easier to work with than mammalian cell cultures.
In summary, mammalian and microbial cell cultures differ in the type of cells they involve, their complexity, and the requirements for growth and expression. Mammalian cell cultures are typically used for more complex protein production, while microbial cell cultures are used for simpler and faster processes.
Comparative Table: Mammalian vs Microbial Cell Culture
Here is a table comparing the differences between mammalian and microbial cell culture:
| Feature | Mammalian Cell Culture | Microbial Cell Culture |
|---|---|---|
| Growth Type | Animal cells grown in flasks or dishes as suspension or adherent culture | Microbial cells grown in the laboratory under controlled conditions |
| Matrix Requirement | Typically require a matrix to adhere | Do not typically require a matrix |
| Culture Conditions | Environmental conditions such as temperature, pH, and gas composition need to be maintained | These conditions are less critical |
| Nutrient Requirements | Growth medium supplemented with nutrients, growth factors, hormones | Growth medium provides necessary nutrients |
| Media Composition | Medium is complex and may contain serum | Medium is often simpler and serum-free |
| Cost and Ease of Use | More expensive and difficult to work with | Less expensive and easier to work with |
Mammalian cell culture involves growing animal cells in an artificially controlled environment, while microbial cell culture involves growing microbial cells in a similar setting. Key differences between the two include the growth type, matrix requirement, culture conditions, nutrient requirements, media composition, and cost and ease of use.
