Application of 3‐Dimensional Printing in Pediatric Living Donor Liver Transplantation: A Single‐Center Experience

Pusen Wang, Weitao Que, Mingman Zhang, Xiaoke Dai, Kanru Yu, Chunguang Wang, Zhihai Peng, Lin Zhong – 15 February 2019 – Three‐dimensional (3D) printing has been used to support organ transplantations. However, whether it helps remains unclear. This study aimed to present and assess the application of 3D‐printed liver models in pediatric living donor liver transplantation (LDLT). The 3D images were printed to touchable liver models with transparent liver parenchyma, specifically colored hepatic vessels, and biliary structures.

Ex Vivo Hepatocyte Reprograming Promotes Homology‐Directed DNA Repair to Correct Metabolic Disease in Mice After Transplantation

Caitlin J. VanLith, Rebekah M. Guthman, Clara T. Nicolas, Kari L. Allen, Yuanhang Liu, Jennifer A. Chilton, Zachariah P. Tritz, Scott L. Nyberg, Robert A. Kaiser, Joseph B. Lillegard, Raymond D. Hickey – 15 February 2019 – Ex vivo CRISPR/Cas9‐mediated gene editing in hepatocytes using homology‐directed repair (HDR) is a potential alternative curative therapy to organ transplantation for metabolic liver disease.

Telomerase Variants in Patients with Cirrhosis Awaiting Liver Transplantation

Victor Chiu, Rachel Hogen, Linda Sher, Niquelle Wadé, David Conti, Anastasia Martynova, Hongtao Li, Gangning Liang, Casey O'Connell – 14 February 2019 – Telomeres are repetitive DNA sequences that protect the ends of linear chromosomes, and they are maintained by a ribonucleoprotein complex called telomerase. Variants in genes encoding for telomerase components have been associated with a spectrum of disease in the lung, skin, bone marrow, and liver.

Lusutrombopag for the Treatment of Thrombocytopenia in Patients With Chronic Liver Disease Undergoing Invasive Procedures (L‐PLUS 2)

Markus Peck‐Radosavljevic, Krzysztof Simon, Angelo Iacobellis, Tarek Hassanein, Zeid Kayali, Albert Tran, Mihaly Makara, Ziv Ben Ari, Marius Braun, Paul Mitrut, Sheng‐Shun Yang, Meral Akdogan, Mario Pirisi, Ajay Duggal, Toshimitsu Ochiai, Tomoko Motomiya, Takeshi Kano, Tsutae Nagata, Nezam Afdhal – 14 February 2019 – Thrombocytopenia may be associated with increased bleeding risk impacting timing and outcome of invasive procedures in patients with chronic liver disease (CLD).

Tissue Repair in the Mouse Liver Following Acute Carbon Tetrachloride Depends on Injury‐Induced Wnt/β‐Catenin Signaling

Ludan Zhao, Yinhua Jin, Katie Donahue, Margaret Tsui, Matt Fish, Catriona Y. Logan, Bruce Wang, Roel Nusse – 14 February 2019 – In the liver, Wnt/β‐catenin signaling is involved in regulating zonation and hepatocyte proliferation during homeostasis. We examined Wnt gene expression and signaling after injury, and we show by in situ hybridization that Wnts are activated by acute carbon tetrachloride (CCl4) toxicity. Following injury, peri‐injury hepatocytes become Wnt‐responsive, expressing the Wnt target gene axis inhibition protein 2 (Axin2).
