Aims: To evaluate the effect of donor liver resident mesenchymal cells, M2 macrophages on liver graft outcome after living donor liver transplantation.
Materials And Methods: Seventy donor biopsies were included in the study. Outcomes at day 3, 7, 30, and 180 postliver transplantation were assessed. Mesenchymal stem cells and M2 macrophages in donor liver biopsies were evaluated.
Results: Mean age of recipients was 40.9 ± 13.6 years. Sex mismatched transplants were 44 (M→F = 9; F→M = 35). On area under receiver operative curve analysis, donor biopsy (DB) nestin ≥3 and CD 163 ≥ 32/200x at day 3; CD163 ≥ 32 at day 7; CD 163 > 32, pRBC of <6.5 units at day 30, and DB nestin ≥3, CD 163 ≥ 32 and pRBC<6.5 units at day 180 predicted adequate graft functions. On multivariate analysis, higher DB nestin (P = .009) and lower cryoprecipitate (P = .009) usage at day 3, higher DB CD163 (P = .006) at day 7, higher DB CD163 (P = .018) and reduced transfusion of packed cell (pRBC) (P = .014) at day 30 and higher DB nestin (P = .011), higher CD163 (P = .009), and reduced pRBC (P = .045) at day 180 were the predictors of better outcome.
Conclusions: Donor liver biopsy nestin+ and CD163+ can predict early graft outcome in living donor liver transplantation.

Background: Liver transplantation is an important treatment option for liver cirrhosis in patients with HIV/HCV coinfection. In Japan, the limited number of deceased donors may force the selection of living donor liver transplantation. Appropriate graft selection is the key to success.

Static cold storage of donor livers at 4 °C incompletely arrests metabolism, ultimately leading to decreases in ATP levels, oxidative stress, cell death, and organ failure. Hydrogen Sulfide (HS) is an endogenously produced gas, previously demonstrated to reduce oxidative stress, reduce ATP depletion, and protect from ischemia and reperfusion injury. HS is difficult to administer due to its rapid release curve, resulting in cellular death at high concentrations.

Background: The viability of the liver pre-transplant depends on the type of donor, age, medical history, circumstances of death, result of analytics, and complementary exploration of the abdominal cavity. Abdominal ultrasound is the initial option for the assessment of previously unknown liver disease, such as the qualitative determination of hepatic steatosis . The presence of hepatic steatosis is considered a risk factor for graft failure after liver transplantation, therefore, at the time of clinical assessment of the donor or its presence in the macroscopic assessment in the operating room can be cause for rejection of the organ by the transplant teams.

Background: The spectrum of metabolic dysfunction-associated steatotic liver disease (MASLD) is highly prevalent, affecting 30% of the world's population, with a significant risk of hepatic and cardiometabolic complications. Different stages of MASLD are accompanied by distinct gut microbial profiles, and several microbial components have been implicated in MASLD pathophysiology. Indeed, earlier studies demonstrated that hepatic necroinflammation was reduced in individuals with MASLD after allogenic faecal microbiota transplantation (FMT) from healthy donors on a vegan diet.

End-stage liver disease includes liver failure and decompensated cirrhosis resulting from various etiologies and often leads to patient mortality due to complications and clinical symptoms such as severe jaundice, ascites, hepatic encephalopathy, coagulopathy, and hepatorenal syndrome. Liver transplantation is currently regarded as the most effective treatment, but its clinical application is limited by the shortage of donors, elevated expenses, and post-transplant rejection. Stem cells are a group of cells with multidirectional differentiation potential and self-renewal ability, which can improve the clinical indicator outcomes through mechanisms such as immunoregulation and promotion of tissue repair in patients with end-stage liver disease.
