BACKGROUND Ischemia-reperfusion (I/R) injury associated with living donor liver transplantation impairs liver graft regeneration. Mesenchymal stem cells (MSCs) are potential cell therapeutic targets for liver disease. In this study, we demonstrate the impact of MSCs against hepatic I/R injury and hepatectomy. METHODOLOGY/PRINCIPAL FINDINGS We used a new(More)
This study investigated adequate liver graft selection for donor safety by comparing postoperative donor liver function and morbidity between the right and left hemilivers (RL and LL, respectively) of living donors. Between April 2006 and March 2012, RL (n = 168) and LL (n = 140) donor operations were performed for liver transplantation at Kyoto University(More)
The development of organ preservation solutions and associated technology has been a major effort in tissue transplantation recently. However, this research takes a great deal of time and resources. In this study, a novel method for the evaluation of preservation solutions was established by using islet cells. Primary islets were obtained by hand-picking(More)
BACKGROUND Liver transplantation (LT) used to be contraindicated in patients with portal vein thrombosis (PVT). In comparison to deceased donor LT, living donor LT (LDLT) still presents additional difficulties in determining appropriate vein grafts and overcoming small-for-size syndrome. Here, we introduce our LDLT strategies and assess their outcomes in(More)
The transjugular portosystemic shunt, widely used to treat portal hypertension today, may increase the risk of encephalopathy and reduce effective hepatic flow. To address these issues, a strategy to produce a portocaval shunt (PCS) with hepatic function using intestinal grafts was conceived, and rat models were developed. We transplanted ileal grafts from(More)
It is thought that the small intestine may provide a scaffold for pancreas regeneration. Herein, we investigated whether fetal pancreatic tissue could be transplanted into the segmental intestine in rats. Fetal pancreases from firefly luciferase transgenic Lewis rat embryos (embryonic day 14.5 and 15.5) were transplanted into streptozotocin (STZ)-induced(More)
BACKGROUND/AIM Worldwide shortage of donor organs has increased the use of donation after cardiac death (DCD). The aim of this study was to analyze the best time point for venous systemic oxygen persufflation (VSOP) supplemented with nitric oxide (NO) gas during the 1st and 24th hour of cold storage (CS) in warm ischemia (WI)-damaged experimental liver(More)
In developing therapeutic alternatives to liver transplantation, we have used the strategy of applying a small intestinal segment as a scaffold for hepatocyte transplantation and also as a portocaval shunt (PCS) system to address both liver dysfunction and portal hypertension. The aim of this study was to investigate the feasibility of such an intestinal(More)
Congenital bile duct dilatation (CBD) that developed in a parent and son is presented. Familial occurrence of CBD is rare, with only a few male cases having been reported. Since the initial report of CBD occurring in siblings in 1981, a total of 20 cases (10 pairs) have been published as of 2007. Clinical and genetic features of CBD are discussed.
BACKGROUND Due to a worldwide shortage of donor organs for liver transplantation, alternative approaches, such as split and living donor liver transplantations, were introduced to increase the donor pool and reduce mortality on liver transplant waiting lists. Numerous details concerning the mechanisms and pathophysiology of liver regeneration,(More)
