ITGAX and neoplasm: We show here that the transfer of newly developed murine tumor dendritic cell (MuTuDC) lines derived from splenic tumors of transgenic CD11c:SV40LgT mice (3, 4) into immuno-deficient hosts (Rag2−/−) and transgene-tolerant mice (transgenic CD11c:SV40LgT) resulted in the development of splenic and hepatic DC tumors.
