Data from ELISA of conditioned media from rat HSCs treated for 24h with leptin (Lep, 100ng/ml), adiponectin (Adi, 10μg/ml), both (LA), or neither demonstrated that leptin stimulated formation of MMP-2/TIMP-1 complexes (*p < 0.05 vs. untreated), while co-administration of adiponectin in the presence of leptin significantly reduced the formation of MMP-1/TIMP-1 complexes compared with leptin alone (#p < 0.05 vs. leptin).
