What is a rapidly growing population of identical cells that produce large quantities of specific antibodies called?

A rapidly growing population of identical cells that produce large quantities of specific antibodies is called a hybridoma. Hybridomas are created by fusing B cells that produce a specific antibody with myeloma (cancer) cells, allowing for the continuous production of the desired antibody. This process is crucial in making monoclonal antibodies, which have numerous applications in research, diagnostics, and therapy.
