The choice of cell line, primary cells, or multicellular developmental model is critical for live cell analysis. Many cellular model systems have particular growth characteristics or behaviors that make them unsuitable for live cell analysis, while others seem ideally suited and can tolerate the sometimes less than ideal “living” conditions often necessary for live cell analysis, particularly for extended time analyses.
Primary cell lines, being extracted directly from tissue, are often an attractive choice in live cell analysis because they are presumably closer to their natural origins and thus may be more relevant in predictive cell culture. There are a large number of primary cultures that can be extracted and maintained from tissues; however, most have similar limitations in growth rate, passaging, and maintaining in vivo-like characteristics. The more passaging that is done, the less a primary cell culture is truly “primary”. They are often less controllable than cell lines so it is widely acknowledged that when using primary cultures, know your source populations well, control their culture environment carefully, and validate their phenotypes periodically (such as with antibody staining patterns and karyotyping).
Example of Primary Cultures Useful for Live Cell Analysis
With the plethora of cell lines available today the choice for investigators is quite large. Many cell lines today have become the “go to” cell line for examining particular cellular events such as apoptosis, or cellular transport. Researchers should certainly consult the growing literature available using live cell analysis and use it for guidance. Instrumentation improvements continue to expand our ability to control and define both the extrinsic and intrinsic factors necessary for even the most sensitive cell cultures.
