摘要

BACKGROUND: Embryo cryopreservation has been used for the creation of genetic banks with diploid resources, and among different techniques, vitrification is considered as the most promising method. OBJECTIVE: The goal is to evaluate the major aspects of the existing vitrification techniques and to evaluate their efficacy in terms of embryo morphology. METHODS: Electronic searches in the PubMed and ScienceDirect databases were performed with the keyword conbination: fish, embryo and vitrification. Pubmed retrieved 26 articles and Science Direct resulted in 464 articles. For this review, only studies that developed and tested vitrification protocols in fish embryos were included. Research regarding cryoprotectant toxicity and permeability were excluded. There were no restrictions on publication date or language. With these criteria, a total of ten articles were evaluated. RESULTS: In these articles, the major aspects to be considered for the development of new vitrification protocols are: the cryoprotectants%26apos; toxicity, the embryos%26apos; development stage, the exposure to and the permeability of the cryoprotectants, vitrification devices and vitrification-warning cycle. CONCLUSION: The survival were limited, however, the preservation of embryonic morphology after thawing indicates the possibility of preserving fish embryos via the vitrification technique.
