CSF2 and melanoma: Engraftment of live GM-CSF-producing B16 melanoma (B16-GM-CSF) (Dranoff et al., 1993) triggered the expansion of (1) circulating MHCII+ monocytes with varying expression levels of Ly6C (Figure S6A) and (2) Lin−Ly6G−CD11b+Ly6Chi–loMHCII+ spleen cells largely overlapping the CD11b+ DC phenotype (Figure S6B).
