Improved survival of orthotopic liver allograft in swine by addition of trophic factors to University of Wisconsin solution.

Serum-free preservation media such as University of Wisconsin (UW) may cause tissue damage through trophic factor (TF) deprivation. This study evaluated whether the addition of TFs to UW solution improves liver graft quality after extended cold preservation time in pigs. UW solution was supplemented with epidermal growth factor, insulin-like growth factor-1, nerve growth factor-beta, bactenecin, and substance P to create TF-supplemented (TFS) UW.
