Part 27 Article: Biotechnology My Blog Title: The world, from the past to the present, retold from the timelines. 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.” Several teams had been working on fast and uniform rewarming of vitrified organs using nanoparticles, with promising results in kidneys. In contrast to partial freezing, supercooling aimed to achieve preservation at below 0°C temperatures while avoiding ice nucleation. The prevention of ice formation had to be done both in the extracellular and intracellular spaces. Extracellular space refers to the part of a ...
