LLGL1 and mastocytoma: investigated the distribution of mRNA for Mgl1 and Mgl2 in 10 mouse cell lines, including L929 (fibroblast line), JLS‐V9 (bone marrow‐derived fibroblast‐like cell line), EL4 (thymoma cell line), RL 1 (lymphoma cell line), YAC‐1 (lymphoma cell line), BCL1‐B20 (malignant B cells), P815 (mastocytoma cells), P388 (Mφ‐like lymphoid cell line), M1 (myeloblastic leukemia cells) and RAW264.7 (Mφ‐like cell line).
