A model of breast cancer heterogeneity reveals vascular mimicry as a driver of metastasis

Different clones of a mammary tumour cell line possess differential abilities to contribute to the formation of metastasis; the expression of Serpine2 and Slp1 proteins drives vascular mimicry and metastasis to the lung, with similar associations observed in human data sets, and these proteins also function as anticoagulants, thus further promoting extravasation of tumour cells.
