In this context, NMP holds promise for expanding the use of marginal donor kidneys by enhancing viability assessment and potentially restoring function in grafts that might otherwise be discarded. In addition, NMP provides a valuable platform for studying molecular markers of injury and recovery in human organs, as well as for delivering targeted therapies aimed at modulating immunologic or transcriptomic profiles.
