One of the most awaited technologies for the preservation of tissue-engineered product is long-term unfrozen storage (more specifically, dry storage) at ambient temperature. This approach allows storage without dependence on expensive freezers or liquid nitrogen, which require daily maintenance. This “off-the-shelf” availability and low cost should facilitate the usage of tissue-engineered products. Unfortunately, this is not yet a reality. However, many organisms can undergo a phenomenon called anhydrobiosis to survive in a completely dehydrated state for an extended time and resume activity upon rehydration (Crowe et al., 2002). The sugar trehalose is found at high concentrations in many anhydrobiotic organisms
