P388 Cells

P388 is a murine lymphoid neoplasm cell line derived from a spontaneous lymphocytic leukemia in DBA/2 mice. It is commonly used in cancer research, particularly for studying leukemia and testing anti-cancer compounds. P388 cells grow in suspension and exhibit a doubling time of approximately 24 hours under optimal culture conditions. The cells are characterized by their rapid proliferation and high sensitivity to chemotherapeutic agents, making them a valuable tool for evaluating the efficacy of new cancer treatments.
P388 cells express typical markers of lymphoid lineage, including surface immunoglobulins and various cell surface antigens associated with B-cells. Researchers often utilize this cell line in in vivo models by inoculating mice to study tumor growth, metastasis, and response to therapies. Additionally, the P388 cell line serves as a model for investigating the molecular mechanisms underlying leukemia, such as the role of specific oncogenes and tumor suppressor genes.
Despite its widespread use, the P388 cell line has limitations, such as the lack of human relevance and potential genetic drift over extended culture periods. Therefore, researchers often complement studies involving P388 cells with other models to obtain a comprehensive understanding of leukemia biology and treatment responses.
