Metastasis-related proteins are expressed in EVs from epithelial MCF-7, the highly aggressive triple negative breast cancer (TNBC)-derived MDA-MB-231, and epithelial T47D cell lines including the interleukins (IL-) IL-6, IL-8, IL-12, vascular endothelial growth factor (VEGF), FGF basic, G-CSF and GM-CSF (Dalla et al., 2020). Here, VEGFA is linked to triple-negative breast carcinoma.
