ITGAM and neoplasm: In the present studies, while we saw no statistically significant difference in the numbers of TAMs per gram tumor between different genotypes (data not shown), we did observe a lower frequency of MDSCs in general (CD11b+GR1+), as well as monocytic (Ly-6GnegLy-6CHi) and granulocytic MDSCs (Ly-6G+Ly-6CLo) in these animals (Figure 5A and 5B, respectively).
