家禽种质资源超低温冷冻保存研究进展OA
Research Advances of Ultra-low Temperature Cryopreservation in Poultry Germplasm Resources
超低温冷冻保存是建立家禽种质资源冷冻库的关键.禽类种质资源冷冻库的建立面临精子低温敏感、卵子无法冷冻、冻后活力下降及遗传物质复原技术不成熟、后代存活时间短等多重挑战.目前家禽遗传物质超低温冷冻保存技术尚不成熟,超低温冷保存效果与冷冻机制等核心问题仍需深入研究.本文主要综述了家禽精液、体细胞、原始生殖细胞(primordial germ cells,PGCs)及性腺组织在超低温冷冻保存方面的研究进展,以期为家禽种质资源超低温冷冻保存提供参考.
Ultra-low temperature cryopreservation is essential for establishing a poultry germplasm bank.The establishment of poultry germplasm cryobanks faces multiple challenges,including the inherent cryosensitivity of spermatozoa,the inability to successfully cryopreserve oocytes,reduced post-thaw viability,immature genetic material resuscitation technologies,and limited survival of offspring.Currently,ultra-low temperature cryopreservation technologies for poultry genetic resources remain underdeveloped,with core issues such as ultra-low temperature cryopreservation efficacy and underlying freezing mechanisms requiring further in-depth investigation.In this paper,advances in the cryopreservation of semen,somatic cells,primordial germ cells(PGCs)and gonadal tissues of poultry were reviewed,and the findings were summarized to provide a reference for the conservation of poultry germplasm resources.
