Cryopreservation of plant cell cultures – Diverse practices and ...
2021年5月25日 · Three approaches have been developed: slow freezing, vitrification, and encapsulation-dehydration. Typically, the protocols are iteratively adapted to accommodate the properties of different plant cell lines, taking time and …
Cryopreservation of tissues by slow-freezing using an emerging
2023年1月2日 · Slow-freezing has a low cooling rate and prevents intracellular ice formation (IIF) by dehydration of cells. Slow-freezing is widely used for dispersed single cells because it works...
Molecular Mechanisms Underlying Freezing Tolerance in Plants
2024年9月20日 · These include slow freezing, vitrification, encapsulation dehydration, encapsulation–vitrification, droplet vitrification, cryo-plates, and cryo-mesh techniques. A key challenge in the advancement of cryopreservation lies in our ability to understand the molecular processes underlying plant freezing tolerance.
Effects of freezing on cell structure of fresh cellular food materials ...
2018年5月1日 · Slow freezing normally forms large ice crystals in the extracellular regions of the frozen foods, which may cause damage to food microstructure, resulting in the color, flavor, nutrition and texture modification after thawing, such as tissue softening, increase in drip loss increasing, reduction in water holding capacity and tenderness, tissue ...
High-Throughput Cryopreservation of Plant Cell Cultures for …
2012年3月21日 · In the simple protocol, a thick expanded polystyrene (EPS) container containing the vials with the cell–LSP solution mixtures was kept at −30°C for 6 h to cool the cells slowly (pre-freezing); samples from the EPS containers were then plunged into liquid nitrogen before long-term storage.
Advances in the slow freezing cryopreservation of microencapsulated cells
2018年7月10日 · Currently slow freezing represents the most appropriate storage method of microencapsulated cells. CPA solution, sample preparation, cooling, thawing and CPA removal must be carefully selected. Several microencapsulated cell types have been successfully cryopreserved in small volumes.

2021年2月1日 · Three approaches have been developed: slow freezing, vitrification, and encapsulation-dehydration. Typically, the protocols are iteratively adapted to accommodate the properties of different...
Efficient long-term cryopreservation of pluripotent stem cells …
2016年10月3日 · For slow freezing, cells are loaded with a low concentration (typically 10% v/v) of cryoprotectant and then slow-cooled to an intermediate temperature, e.g. −80 °C in a deep freezer 20.
Responses of the Plant Cell Wall to Sub-Zero Temperatures: A Brief ...
2021年7月8日 · Understanding how tissue-specific cell-wall modifications in woody xylem parenchyma, dormant buds, tissues associated with plant meristems in grasses and herbs are key to advancing our understanding of plant freezing tolerance and avoidance. We can visualize tissue-level phenotypes using high-definition infrared thermography, nuclear magnetic ...
Cryopreservation of Plant Cell Lines | SpringerLink
2014年11月14日 · Most of the different cryopreservation approaches, which are generally used for plant tissues, have also been applied to plant cell cultures; they include slow freezing, vitrification, and encapsulation/dehydration approaches.
