sejtvonal

Sejtvonal refers to a specific type of cell line used in biological research. It is a population of cells that have been cultivated in vitro and can be perpetuated indefinitely. This indefinite propagation is typically achieved through a process known as immortalization, which can occur spontaneously or be induced. Immortalized cell lines are valuable tools because they provide a consistent and renewable source of cells for various experimental applications.

The term "sejtvonal" is Hungarian and translates directly to "cell line." These lines are derived from a single cell or a small population of cells that have undergone genetic changes allowing them to bypass normal cellular senescence. Senescence is a process where cells stop dividing after a certain number of divisions. Immortalized cells overcome this limitation, enabling researchers to grow large quantities of genetically identical cells over extended periods.

Sejtvonalok are widely used in numerous scientific disciplines, including molecular biology, genetics, drug discovery, and cancer research. They allow for reproducible experiments and the study of cellular processes in a controlled environment. Different sejtvonalok can originate from various tissues and organisms, offering a diverse range of models for studying specific biological phenomena. For instance, some sejtvonalok are derived from human tumors, making them particularly useful for investigating cancer mechanisms and testing potential therapies.
