Fig. 7

A The therapeutic effects of SFC-derived exosomes on OA are mainly reflected in the following three parameters. (1) reduction of inflammatory cytokines, (2) inhibition of apoptosis, and (3) modulate miRNA-126-3p in exosome to promote the therapeutic efficiency. B The exosomes derived from SFC could mediate cell–cell communications and regulate diverse cell phenotype including inflammatory reaction, cell proliferation, migration, apoptosis and etc.
