What is a cell line in a cell culture?

A cell line in a cell culture is a group of cells that have been derived from the same parent cells and are therefore genetically identical. These cells can be grown and maintained in a laboratory setting under controlled conditions, making them useful tools for a wide range of applications, including drug development, vaccine production, and fundamental research into cell behavior and function. By studying cell lines, researchers can gain insights into how cells interact with each other and with their environment, and can use this information to develop new treatments and therapies for a variety of diseases and conditions.
