Some of the changes observed in the triple‐negative cells comprised (a) an increase in cancer stem cell markers, similar to what was found in collagen and spheroid models,44 (b) higher expression of the hypoxia‐inducible factor HIF1α, which promotes angiogenesis and capability to metastasize,45 and (c) an NFκB‐mediated inflammatory signature. Here, NFKB1 is linked to cancer.
