Meaning and Definition
A population of cells, derived from a single cell or a specific tissue, which can be grown in a laboratory and continues to divide indefinitely under appropriate conditions.
In biotechnology and research, a standardized biological resource used for experiments, testing, and production of biological compounds. It can also refer metaphorically to a specific lineage or type of cultured cells with distinct, stable characteristics.

FAQ
Frequently Asked Questions
Not exactly. 'Cell culture' is the general process and environment for growing cells. A 'cell line' specifically refers to a defined population of cells that has been subcultured (passaged) beyond the primary culture stage and often has the potential for indefinite growth.
It means the cells have been altered (naturally through cancer or experimentally) to bypass normal cellular senescence (aging), allowing them to divide indefinitely under lab conditions, forming a continuous cell line.
They provide a consistent, renewable, and standardized source of biological material. This allows experiments to be replicated in different labs and over time, reducing variability compared to using fresh tissue samples from different sources.
The HeLa cell line, derived from Henrietta Lacks' cervical cancer cells in 1951. It was the first immortal human cell line and has been used in countless medical breakthroughs, raising significant ethical questions about consent and bio-specimen ownership.
A population of cells, derived from a single cell or a specific tissue, which can be grown in a laboratory and continues to divide indefinitely under appropriate conditions.
Cell line is usually technical/scientific (specialized) in register.
