Figure 2. Bone marrow-derived cells (BMDCs) are recruited to the tumor microenvironment.
(A) Representative photomicrographs of tumor cross sections from GFP+ bone marrow transplanted mice counterstained with CD31+ at low- (n=4) and high-grade stages (n=4)(4 and 8 weeks, respectively), Scale bar 50μm. (B) Representative flow cytometric analysis of brain tumor tissue from RCAS murine animals gated for GFP+ cells in low (n=4) and high grade tumors (n=4), * p<0.05. (C) Confocal microscopic analysis of high grade tumor sections (n=3 animals, >6 sections/tumor) stained for DAPI and CD11b from GFP+ bone marrow transplanted RCAS mice, Scale bar 50μm(D) Quantification of cells labeled with GFP+, CD11b+, and co-stained (GFP+/CD11b+). Percentage of CD11b+/GFP+ cells.
