A cell line is a population of cells that are genetically identical and derived from a single cell through cell division. Cell lines are commonly used in biological and medical research to study various cellular processes, gene expression, and disease mechanisms.
Cell lines can be derived from various sources, such as animal tissues, human tissues, or microorganisms. They can be immortalized or transformed through genetic modifications or viral infections, allowing them to divide and proliferate indefinitely in culture.
Cell lines can be grown in culture using various techniques, such as suspension culture, adherent culture, or 3D culture. They can be maintained in the laboratory over long periods of time, allowing for consistent and reproducible experimental results.
Cell lines are important tools in biological and medical research, as they allow researchers to study cellular processes and functions in a controlled and reproducible manner. They are commonly used in drug discovery and development, disease modeling, and basic research on cell biology and genetics.
However, it is important to note that some cell lines may differ from their tissue of origin in terms of genetic or phenotypic characteristics, and the interpretation of experimental results obtained from cell lines should be done with caution and validated using appropriate in vivo or ex vivo models.
