The HµREL microlivers’ patent-pending, specially engineered packaging maintains 25˚C – 37˚C during travel to any destination world-wide, and keeps the cells ready for immediate, plug-and-play use after a brief, 4-hour media refreshment upon arrival.  No tissue culture or multi-day reacclimatization is required.  Shipping “warm” preserves the microlivers’ phenotype and high, stable, long-enduring metabolic competency.
