Efficient human fetal liver cell isolation protocol based on vascular perfusion for liver cell–based therapy and case report on cell transplantation

Bruno Gridelli, Giovanni Vizzini, Giada Pietrosi, Angelo Luca, Marco Spada, Salvatore Gruttadauria, Davide Cintorino, Giandomenico Amico, Cinzia Chinnici, Toshio Miki, Eva Schmelzer, Pier Giulio Conaldi, Fabio Triolo, Jörg C. Gerlach – 27 October 2011 – Although hepatic cell transplantation (CT) holds the promise of bridging patients with end‐stage chronic liver failure to whole liver transplantation, suitable cell populations are under debate.

Growth‐hormone–induced signal transducer and activator of transcription 5 signaling causes gigantism, inflammation, and premature death but protects mice from aggressive liver cancer

Katrin Friedbichler, Madeleine Themanns, Kristina M. Mueller, Michaela Schlederer, Jan‐Wilhelm Kornfeld, Luigi M. Terracciano, Andrey V. Kozlov, Susanne Haindl, Lukas Kenner, Thomas Kolbe, Mathias Mueller, Kenneth J. Snibson, Markus H. Heim, Richard Moriggl – 26 October 2011 – Persistently high levels of growth hormone (GH) can cause liver cancer. GH activates multiple signal‐transduction pathways, among them janus kinase (JAK) 2‐signal transducer and activator of transcription (STAT) 5 (signal transducer and activator of transcription 5).

Human liver cell spheroids in extended perfusion bioreactor culture for repeated‐dose drug testing

Rui M. Tostões, Sofia B. Leite, Margarida Serra, Janne Jensen, Petter Björquist, Manuel J. T. Carrondo, Catarina Brito, Paula M. Alves – 26 October 2011 – Primary cultures of human hepatocyte spheroids are a promising in vitro model for long‐term studies of hepatic metabolism and cytotoxicity. The lack of robust methodologies to culture cell spheroids, as well as a poor characterization of human hepatocyte spheroid architecture and liver‐specific functionality, have hampered a widespread adoption of this three‐dimensional culture format.

Hepatitis C virus reinfection and superinfection among treated and untreated participants with recent infection

Jason Grebely, Son Truong Pham, Gail V. Matthews, Kathy Petoumenos, Rowena A. Bull, Barbara Yeung, William Rawlinson, John Kaldor, Andrew Lloyd, Margaret Hellard, Gregory J. Dore, Peter A. White, on behalf of the ATAHC Study Group – 26 October 2011 – The purpose of the study was to evaluate reinfection and superinfection during treatment for recent hepatitis C virus (HCV). The Australian Trial in Acute Hepatitis C (ATAHC) was a prospective study of the natural history and treatment of recent HCV.
