EVs secreted by invasive tumoroids (3D d10‐d14) included proteins promoting tumour growth (solute carrier family 12 member 2, SLC12A2; sodium bicarbonate cotransporter 3, SLC4A7) (Demian et al., 2019; Lee et al., 2016), tumour invasion (fatty acid binding protein 5, FABP5) (O'Sullivan & Kaczocha, 2020) and immunosuppression (cluster of differentiation 73, CD73) (Gao et al., 2014). Here, SLC2A12 is linked to neoplasm.
