Abstract:

Cryopreservation of embryos is important for long-distance embryo transfer and conservation of genetic resources. However, porcine embryos are sensitive to low temperatures due to their high cytoplasmic lipid content, which increases the difficulty of their preservation. Studies have indicated that techniques such as reducing lipid content and optimizing medium composition can significantly enhance the efficiency of porcine embryo cryopreservation. Additionally, protecting the cytoskeleton and restoring mitochondrial function are also crucial strategies that contribute to this advancement. These improvements collectively foster the broader application and sustainable development of this critical technology.Therefore, this article introduces embryo cryopreservation and summaries multiple methods and measures to improve embryo freezing efficiency. Meanwhile, the writers'team will focus more on the mechanism of cryopreservation of porcine embryos by discussing the intrinsic properties of embryos and the effects of cryopreservation on transcriptome alteration to help people better understand and advance research on porcine embryo cryopreservation.
