The book "Cancer Cell Lines" provides a comprehensive description of all established human leukemia and lymphoma cell lines that continuously grow under standardized in vitro conditions. These cell lines originate from various hematopoietic lineages, including B and T lymphocytes, natural killer cells, granulocytic cells, and megakaryocytic cells. Clinical data, culture conditions, and the key phenotypic characteristics of the cell lines are detailed, supported by relevant citations. This work is the first of its kind to specifically address human leukemia and lymphoma cell lines and is aimed at scientists in the fields of hematology, oncology, immunology, molecular biology, and cytogenetics. The three volumes provide a comprehensive resource for researchers working with human cancer cells.
