ITGAX and neoplasm: Using flow cytometry and quantitative imaging approaches to characterize the site of engraftment 4 h after tumour inoculation, we found that CD11c+MHCII+ cells represent the predominant leukocyte subset, with higher numbers of these cells when tumour cells were inoculated at ZT9 compared with ZT21 (Fig. 2a–c and Extended Data Fig. 3a–c).
