Are you hearing more about Transient Warming Events in the Cell and Gene Therapy ecosystem?
♨️ A Transient Warming Event (TWE) occurs when a cryopreserved sample is exposed to warmer-than-intended temperatures for any period of time, including the time it takes to remove a sample from the freezer. A temperature excursion like this might seem insignificant at first, but even brief exposure to higher temperatures can compromise the integrity of the frozen cells post-thaw.
♨️ In the latest Cytotherapy journal, Canadian Blood Services and Robert Ben of Panthera CryoSolutions (part of BioLife Solutions), explore TWEs and how different cryosolutions can impact stem cell grafts.
♨️ The study identifies ice recrystallization during warming as a dominant mechanism of cryoinjury and shows that the addition of ice recrystallization inhibitors (IRI) can effectively mitigate TWE-induced damage.
