畜禽遗传资源保存方法中,生殖细胞的冷冻保存因其遗传资源保存的稳定性和长效性,是目前进行畜禽保种的一种主要手段。文章对鸡精液、原始生殖细胞、囊胚细胞、睾丸细胞、性腺细胞以及卵巢组织等生殖细胞的冷冻技术及在遗传资源保存和应用进行了综述,并对不同生殖细胞的保存效果进行了比较。
In the method of conserving livestock genetic resources, cryopreservation of germ cells is one of the main means of preserving livestock and poultry because of the stability and long-term preservation of their genetic resources. In this paper, the freezing techniques of chicken semen, primordial germ cells, blastocysts, testis cells, gonadal cells and ovarian tissues and other germ cells were summarized, and the preservation and application of genetic resources were reviewed. The preservation effects of different germ cells were compared.
