In three - dimensional ( 3D ) cell cultures consisting of MCF - 7 breast cancer cell spheroids that were placed on lymph - endothelial cell ( LEC ) monolayers , tumour cell spheroids induce " circular chemorepellent - induced defects " ( CCIDs ) in the LEC monolayer ; 12 ( S ) - Hydroxyeicosatetraenoic acid ( 12 ( S ) - HETE ) and NF - kappa B activity are major factors inducing CCIDs , which are entry gates for tumour emboli intravasating the vasculature .
