Study Notes
Cell Culture Basics
- Cryopreservation in cell culture allows for the long-term storage of cells, preserving their viability and characteristics for future use.
In Vivo vs. In Vitro Cell Culture
- In vivo cell culture refers to the growth of cells within a living organism, whereas in vitro cell culture involves the growth of cells outside of a living organism, in a controlled laboratory environment.
- The main difference between in vivo and in vitro cell culture lies in the presence of a living organism, with in vitro cultures being more controlled and manipulated.
Applications of Cell Lines
- Cell lines are used in cell culture to study cellular biology, develop and test new therapies, and produce biological products, such as vaccines and antibodies.
Maintaining Cell Cultures
- The primary role of maintaining cultures of animal cells and established cell lines is to ensure a steady supply of cells for research, development, and production purposes.
- Maintaining cultures with good viability and minimal contamination is crucial for obtaining reliable and accurate results.
Special Media in Cell Culture
- The special media used in cell culture are designed to support the growth and survival of cells, with key features including a controlled pH, temperature, and nutrient composition.
- These media may also include supplements, such as antibiotics and growth factors, to enhance cell growth and survival.
