Core Tip

Core tip: Appropriate stimulation of adipose-derived stem cells with thioacetamide (TAA) led to the production of a secretome enriched with proteins, especially peroxiredoxin-1, with higher antioxidant activity. Free radicals are principal pathogenic agents in the pathogenesis of TAA-induced hepatic injury. The TAA-induced secretome was superior to the naïve secretome in restoring hepatic function while minimizing inflammatory processes in mice with TAA-induced hepatic failure. However, it was less effective in the mice with partial hepatectomy, suggestive of disease-specificity. Our results suggest that appropriate stimulation of adipose-derived stem cells with pathogenic agents can lead to the production of a secretome specialized for protecting against the pathogen.
