Abstract
Determination of organ viability over a period of time is a key technology in the process of organ preservation. However, a robust methodology to address this issue has not been established. Luciferase-expressing organs enable the assessment of the variances in organ viability over time as well as the visualization of a damaged tissue region. Herein, we introduce the assessment method for organ viability in detail using luciferase-expressing organs harvested from transgenic Lewis rats (Luc-LEW Tg rats). We exemplify the femoral muscle pedicle flap for the methods of tissue preparation, of setting up the machine perfusion system, and of measuring emitted light to assess organ viability. This evaluation method would be applicable to other organ-preservation studies as an innovative tool for developing a profound understanding of organ preservation.
