Core Tip

Core tip: Hepatic sinus is important in the liver microcirculation, which is the basis for transplanted liver regeneration. Transplanted liver grafts with disturbed microcirculation of the hepatic sinus may affect liver energy metabolism. We investigated the protective effects of heme oxygenase-1-modified bone marrow mesenchymal stem cells (HO-1/BMMSCs) on rat reduced-size liver transplantation in terms of the microcirculation and hepatic energy metabolism. HO-1/BMMSCs promoted the equilibrium of ET-1/NO, repaired damaged hepatic sinusoidal endothelial cells, and lowered the portal vein pressure in rats following reduced-size liver transplantation, which improved the microcirculation of hepatic sinusoids and ATPase activity, and recover the energy metabolism of damaged hepatocytes.
