VEGFA and rheumatoid arthritis: MSC-exosomal miR-150-5p suppressed the expression of the target genes MMP14 and VEGF by directly binding to their 3'-UTRs, thereby reversing the migration and invasion of RA-FLS and HUVEC tube formation induced by pro-inflammatory factors, including IL-1β, transforming growth factor β (TGF-β), and TNF-α.
