During
cryopreservation, the samples survival will depend on the glassy state of explants, that is, the direct transition of water from liquid to an amorphous or glassy solid (Engelmann, 2011).
A further advantage of
cryopreservation over conventional storage techniques is that once in cryogenic storage there is virtually no risk of new microbial contamination and the development of disease.

The ability to freeze and store cells for cell-based therapies and research has taken a step forward in the paper 'A synthetically scalable poly(ampholyte) which dramatically Enhances Cellular
Cryopreservation.' published by the University of Warwick's Department of Chemistry and Medical School in the journal Biomacromolecules.
The researchers hope to apply their method to preserve various types of cells, including those that have been particularly sensitive to the
cryopreservation procedure.
Embryo
cryopreservation is the most established fertility preservation method for BC patients who have male partners, or for those women who are using donor sperm, but it has several ethical and legal concerns such as prohibition of this method in some countries, posthumous reproduction or divorce (20).
Cryopreservation is thus the most promising option for the long-term storage of recalcitrant seeded species (Walters, Berjak, Pammenter, Kennedy, & Raven, 2013).
The agreement allows LenioBio to use Fraunhofer IME's proprietary vector solution and technology for the
cryopreservation of cell lysates.
The American Society of Clinical Oncology (ASCO) has recently updated its guidelines for fertility preservation in cancer patients according to same pregnancy rate results obtained from both oocyte and embryo
cryopreservation which were reported by American Society for Reproductive Medicine (ASRM) (10).
This program aims to lead the research and development (R and D) for the design of a stand-alone urban-farm system and establish protocols for micropropagation,
cryopreservation and nursery management of rare, endangered and economically valuable native plant species.
