As indicated by immunofluorescence staining and qRT‐PCR, after culture in MFC‐CM, mMSCs expressed higher levels of α‐SMA protein, FAP protein, and several tumor‐promoting cytokine genes including interleukin (IL)‐6, chemokine (C‐X‐C motif) ligand 15 (CXCL15), chemokine (C‐C motif) ligand 2 (CCL2), and vascular endothelial growth factor (VEGF) (Fig. 2A and B). Here, VEGFA is linked to neoplasm.
