Core Tip

Core tip: Despite the rapid proliferation of future liver remnant induced by associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), the high mortality and morbidity rates have remained alarming. A plausible reason was the functional proliferation lagged behind the increase in volume. In this study, a rat model was established to evaluate the maturity of ALPPS-derived hepatocytes. Through the identification of hepatic characteristics, detection of liver function, and analysis of functional gene expression, we revealed the immaturity of ALPPS-derived proliferation in early regenerative response, which indicated that the volumetric assessment overestimated the functional proliferation. And clinically, the stage II of ALPPS should be performed prudently in patients with marginally adequate FLR, as the ALPPS-derived proliferation in volume lags behind the functional regeneration.
