Despite these observations, an aggregation assay (1.5 h aggregation) in the presence of an anti- ICAM1 neutralising antibody showed that, although the homotypic aggregation BC cell-BC cell and vCAF-vCAF was significantly inhibited, no significant effect was observed in the heterotypic clustering BC cell-vCAF (Figure 6C). This evidence concerns the gene ICAM1 and breast cancer.
