We outline the near 50-year history of leukemia-lymphoma (LL) cell lines - a key model system in biomedicine. Due to the detailed documentation of their oncogenomic and transcriptional alterations via recent advances in molecular medicine, LL cell lines may be fitted to parent tumors with a degree of precision unattainable in other cancers. We have surveyed the corpus of published LL cell lines and found 637 examples that meet minimum standards of authentication and characterization. Alarmingly, the rate of establishment of new LL cell lines has plummeted over the last decade. Although the main hematopoietic developmental cell types are represented by cell lines, some LL categories stubbornly resist establishment in vitro. The advent of engineering techniques for immortalizing primary human cells that maintain differentiation means the time is ripe for renewed search for in vitro models from un(der)represented hematologic entities. Given their manifold applications in biomedicine, there is little doubt that LL-derived cell lines will continue to play a vital part well into the next half-century as well.
