Frédéric P. Lemaigre – 12 December 2014 – Slow renewal of the epithelial cells by proliferation ensures homeostasis of the liver, but extensive proliferation may occur upon injury. When proliferation is impaired, transdifferentiation of mature cells or differentiation of stem cells allows production of new hepatocytes and cholangiocytes. While lineage tracings using cyclization recombinase (Cre) recombinase–mediated cell labeling represent the gold standard for defining cell fate, there are more variables than was initially realized.

Pratima Sharma, Douglas E. Schaubel, Nathan P. Goodrich, Robert M. Merion – 11 December 2014 – Hyponatremia is associated with elevated wait‐list mortality among end‐stage liver disease candidates for liver transplantation (LT). However, the effect of low serum sodium on the survival benefit of LT has not been examined. We sought to determine whether pretransplant hyponatremia is associated with an altered LT survival benefit. Data were obtained from the Scientific Registry of Transplant Recipients.

Ruo‐Lang Pan, Li‐Xin Xiang, Ping Wang, Xiao‐Yuan Liu, Li Nie, Wendong Huang, Jian‐Zhong Shao – 11 December 2014 – Liver fibrosis, a major cause of end‐stage liver diseases, is closely regulated by multiple growth factors and cytokines. The correlation of fibroblast growth factor 2 (FGF2) with chronic liver injury has been reported, but the exact functions of different FGF2 isoforms in liver fibrogenesis remain unclear.

Fotios Sampaziotis, Charis‐Patricia Segeritz, Ludovic Vallier – 11 December 2014 – Liver disease is a leading cause of death in the Western world. However, our insight into the underlying disease mechanisms and the development of novel therapeutic agents has been hindered by limited availability of primary tissue, intraspecies variability associated with the use of animal models, and reduced long‐term viability of isolated and diseased liver cells.

Hong‐Yuan Hsu, Mei‐Hwei Chang, Yen‐Hsuan Ni, Cheng‐Lun Chiang, Jia‐Feng Wu, Huey‐Ling Chen – 11 December 2014 – To determine whether universal infant immunization affects occult hepatitis B virus (HBV) infection (OBI), serum samples from hepatitis B surface antigen (HBsAg)‐negative subjects <18 years enrolled during six sequential seroepidemiological surveys conducted between 1984 (just before universal infant immunization) and 2009 were analyzed. Study subjects were divided into unvaccinated cohorts (born before 1984) and vaccinated cohorts (born after 1984).
