Click on PDF to download from Part 3 2023: [10.23] The first successful transplant of a functional cryopreserved mammalian kidney was reported. The study demonstrated a "nano-warming" technique for vitrification for up-to-100 days preservation of transplant organs. Sourced from [frontiersin.org] titled: “Supercooling: a promising technique for prolonged preservation in solid organ transplantation, and early perspectives in vascularized composite allografts.” Nature-inspired molecules like Trehalose, a complex sugar used by plants to avoid freezing, had also been experimented with. Different protocols were tested for various organs, involving diverse processes. A sugar called trehalose, which occurs in organisms capable of surviving extreme dehydration, is used for freeze-drying methods of cryopreservation. Trehalose stabilizes cell membranes, and it is particularl...
