Being the winner of the Rising Stars Video Session organised by the YPT Committee at the ESOT2015 Brussels Congress Karl Hillebrandt gave an interview for the ESOT | YPT webpage.

His abstract "Optimized decellularization of rat livers byarterial and portal venous perfusion underoscillating pressure conditions" and the accompanying video were the most voted at the Rising Stars Session, where the audience voted live for the best video abstract. You can read Karl's abstract in the special ESOT2015 issue of Transplant International.

European Surgical Research accepted our latest paper entitled "Implantation of a tissue engineered Neo Bile Duct in domestic pigs" for publication. Authors are B. Struecker, K. Hillebrandt, N. Raschzok, K. Jöhrens, A. Butter, P. Tang, A. Andreou, H. Napierala, D. Polenz, A. Reutzel-Selke, T. Denecke, J. Pratschke, and I.M Sauer.

Extrahepatic bile duct injuries remain severe complications during cholecystectomy and often require reconstruction by bilioenteric anastomosis (i.e. hepatico-jejunostomy), which comes along with further long-term complications (e.g. recurring ascending cholangitis, secondary biliary cirrhosis). Furthermore, in case of inherent extrahepatic biliary atresia or during liver transplant artificial or engineered bile ducts could enable novel surgical strategies without the need for hepatico-jejunostomy. We present data on the implantation of in vitro generated Neo Bile Ducts in five domestic pigs. Neo Bile Ducts were engineered through decellularization of allogeneic blood vessels and recellularization with autologous cholangiocytes.On postoperative days 0, 1, 7 and 14 blood samples were taken and analyzed (AST, ALT, Bilirubin, Alkaline Phosphatase, Creatinine and Leukocytes). An magnetic resonance cholangiography was performed on postoperative day 14 with one pig. 14 days after implantation pigs were sacrificed and bile ducts were explanted. All pigs survived the complete study period without severe complications. None of the pigs showed signs of biliary leakage or peritonitis. Neo Bile Ducts were infiltrated by neutrophils and neo-angiogenesis was observed around and into the implanted tissue. Whether the presented technique enables the long-term replacement of native bile ducts has to be further evaluated.

Karl Hillebrandt won this year's YPT Rising Stars Video Session Award. He presented the studies on „Optimized decellularization of rat livers by arterial and portal venous perfusion under oscillating pressure conditions“ during the 17th congress of the European Society for Organ Transplantation (ESOT) 2015 in Brüssel. Young Professionals in Transplantation (YPT) is a forum for junior professionals throughout Europe working in the field of transplantation.

Rebeka Major: BIH Promotionsstipendium
Rebeka Major successfully applied for the BIH-Promotionsstipendium grant. Her work will focus in the role of the INDY („I’m Not Dead Yet“) gene in liver regeneration – a project in cooperation with Prof. A. Birkenfeld, Universitätsklinikum Carl Gustav Carus in Dresden.
In the Berlin Institute of Health (BIH), the Max Delbrück Center for Molecular Medicine (MDC) and the Charité - Universitätsmedizin Berlin have joined forces. The core idea is to combine translational research with an overarching systems medicine approach to bridge the gap between basic research and clinical application.
