Effect of Cryopreservation on the Ex Vitro Establishment of Olive Plants Regenerated via Somatic Embryogenesis

open access: yesPlants, 2021
Cryopreservation is considered the best technique for the safe, long-term conservation of embryogenic cultures. However, before integrating it into a somatic embryogenesis system, the influence of cryopreservation on the final production of plants should

Stepped vitrification technique for human ovarian tissue cryopreservation [PDF]

open access: yes, 2019
The advantage of stepped vitrification (SV) is avoiding ice crystal nucleation, while decreasing the toxic effects of high cryoprotectant concentrations. We aimed to test this method for human ovarian tissue cryopreservation.

Cryopreservation of Byrsonima intermedia embryos followed by room temperature thawing [PDF]

open access: yes, 2015
Byrsonima intermedia is a shrub from the Brazilian Cerrado with medicinal properties. The storage of biological material at ultra-low temperatures (-196°C) is termed cryopreservation and represents a promising technique for preserving plant diversity ...

Cryoprotectant-free vitrification of human spermatozoa in new artificial seminal fluid [PDF]

open access: yes, 2016
Vitrification is a new method that has been recently introduced in Assisted Reproduction Technique programs. The aim of this study was to design a new medium similar to normal human seminal fluid (SF), formulation artificial seminal fluid (ASF), and to ...
