The following cell lines were used: CT26, a carcinogen-induced, undifferentiated colon carcinoma obtained from BALB/c mice (51); TS/A, a mouse mammary adenocarcinoma derived from BALB/c mice (52); MCA203, a C57BL/6-derived fibrosarcoma (53); and B16-GM, a C57BL/6 melanoma cell line genetically modified to secrete GM-CSF (54). The 4T1-HA cell line was obtained by lentiviral transduction of 4T1 mammary carcinoma and was provided by K. Whartenby (Johns Hopkins University, Baltimore, MD). These cell lines were grown in DMEM or RPMI 1640 (Invitrogen) with 10% FBS (Invitrogen). The C26GM cell line derived from the C26 colon carcinoma was genetically modified to produce GM-CSF (8) and was grown in the presence of 800 �g/ml G418.
