To this end, TNBC:MSC “Contact” co-cultures were established for 67 h with TNFα stimulation, leading to high CXCL8 levels and clear changes in tumor cell morphology (Figures 13A,B); then, TNFα was removed and the growth of TNBC:MSC “Contact” co-cultures was continued in TNFα-deprived medium for ~2 weeks. This evidence concerns the gene TNF and neoplasm.
