"Cryopreservation doesn’t just preserve genetic lineages – it transforms extinction from a permanent loss into a temporary inconvenience we can choose to address later."

Cryolab has published a clinical comparison of vitrification vs slow freezing for IVF laboratories.

Oocyte survival 90%+ with vitrification vs 50–80% with slow freezing. Blastocyst survival 95%+ vs 70–85%. ESHRE 2020 guidelines recommend vitrification for oocytes and embryos. Slow freezing remains standard for sperm banking.

High-pressure freezing is a novel #cryopreservation technique that utilizes extreme pressure and rapid cooling to instantaneously freeze biological samples into a noncrystalline solid state via vitrification.

Successful use of high-pressure freezing for cell cryopreservation

A high-pressure method of instantaneously freezing cells proves to be effective in the first empirical validation of its kind.

Oh wow! Potentially crucial technical breakthrough for #cryopreservation! Individuals were frozen, placed in liquid nitrogen and then successfully revived 12 months later!

Obviously, that was done in #drosophila - what did you think? 😆

Permeabilization with fenchone enhances cryopreservation of Drosophila embryos

Abstract. The difficulty of cryopreservation has long been a limitation of Drosophila melanogaster as a genetic model organism. Here, we report a statistic

La UVigo logra criopreservar un gusano marino que sirve de modelo en estudios de neurociencia y desarrollo

La UVigo ha establecido el primer protocolo para criopreservar un gusano marino que forma parte de la fauna de las rías gallegas y cuya utilización como modelo para estudios de neurociencia, desarrollo y biología evolutiva va en aumento en todo el mundo. El logro es fruto de la colaboración entre investigadoras del Centro de Investigación Mariña (CIM) y expertos del Max Perutz Labs (Universidad de Viena) que cuentan con un biobanco de la especie Platynereis dumerilii para sus trabajos.

When storing organs outside the body by freezing them, there is the problem that the tissue may be damaged by ice crystal formation. For this reason it has been studied under which conditions glass can solidify without building up too much thermal stress. Using suitable solutions it looks feasible to bring and keep organs in a glass-like state without damaging them. See http://www.neat-news.com/3472.php. #cryopreservation #organ

Project to ‘freeze’ decline of iconic butterfly

A groundbreaking project has been launched to help protect one of the UK’s most spectacular insects – the British Swallowtail butterfly. The British Swallowtail’s population has significantly declined over the last 20 years and researchers from Anglia Ruskin University (ARU) in England are working with Jimmy’s Farm & Wildlife Park and Nature’s SAFE, a UK biobank specialising in conservation, to investigate if cryopreservation can support the long-term conservation of the species. It is believed this is the first time that cryopreservation, where the eggs will be stored in liquid nitrogen at -196 Celsius, has been attempted with butterflies.
