A cell culture model that recapitulates CS-WR was used as previously described.17 (link) Briefly, a confluent monolayer of ECs underwent a 6-hour period of cold ischemia in University of Wisconsin (UW) solution (Bridge to Life, SC) at 4°C in a sealed hypoxic chamber preflushed with pure nitrogen (Airgas, SC). After cold ischemia, UW was removed and replaced with warm culture media to stimulate reperfusion injury. For mPTP modulation, 1μM NIM811 was added to the reperfusion media.
