The experimental procedure and the mechanism by which the ASC-secretome promotes liver regeneration. The model of liver ischaemia-reperfusion combined with partial hepatectomy was established by laparoscopy. The ASC-secretome of miniature pigs was prepared and injected into the liver parenchyma immediately after the operation. The ASC-secretome exerted obvious anti-inflammatory and liver regenerative effects. The mechanism may be as shown in Fig. 5. After partial hepatectomy, the STAT3 signalling pathway was activated to promote the proliferation of hepatocytes. Furthermore, a SOCS3 negative feedback loop was activated to terminate the STAT3 signalling cascade. The ASC-secretome acted on SOCS3 to reduce its expression and interrupted the negative feedback regulation of the STAT3 signalling pathway, accelerating the process of liver regeneration. Cytokines in the ASC-secretome regulate inflammation and promote liver regeneration.
