cell line

A cell line is a population of cells that have been cultured or grown in a laboratory setting and can reproduce indefinitely under specific conditions. These cells are usually derived from a single type of cell, making them genetically similar and useful for research. Scientists use cell lines to study basic biological processes, test new drugs, and explore diseases, as they provide a consistent and controlled environment. By using cell lines, researchers can gain insights that may lead to medical advancements while minimizing the need for animal testing.
