Cell culture as a molecular and biomedical science technique would not have fully developed if not for some key innovations that allowed its application in many research laboratories and industries today.
- Development of antibiotics: The use of antibiotics in cell culture techniques has helped to prevent many microbial contamination that plagued earlier cell culture attempts.
- Development of techniques that allowed the use of proteolytic enzymes such as trypsin. Trypsin helps to remove cells from cell culture vessels or flasks.
- Development of standardized chemically defined growth media which made it easier to culture cells in vitro. DMEM is universally used as growth medium for cell culture technique.
- The development of laminar flow cabinet or hood. The hood provides sterile environment for undertaking cell culture experimentations. It also protects the environment and the researcher from potential contamination.
- The development of powdered tissue culture media, glass culture flasks and improved filtration techniques and products.
BASIS FOR A SUCCESSFUL CELL CULTURE
Having a cell culture without any form of contamination is paramount in the cell culture laboratory. Such success is usually achieved when the laid down principles and aseptic techniques for undertaking a cell culture procedure are conscientiously followed. A successful cell culture technique depends on a number of factors.
- The quality of cell lines you are working with.
- The quality of reagents and cell culture media used.
- The aseptic technique used.
- The quality of the laboratory equipment used and their operation.
- The experience of the researcher.
When these factors are met and made available prior to undertaking cell culture experimentation, it is expected that the cell culture technique will be successful.
