摘要
孤雌生殖是一种独特的生殖方式,指的是卵母细胞在不经过受精的情况下,可以自发或通过物理、化学刺激发育为正常个体,而无需精子参与。在低等动物中,孤雌生殖可以仅由雌性个体完成,从而实现从单个雌性个体产生后代。然而在哺乳动物中,能够通过孤雌生殖发育为正常个体的实例极为罕见。该文介绍了孤雌激活的方式,孤雌胚胎获取方式和印记基因在孤雌生殖中的应用,以期为未来孤雌生殖的相关应用提供思路。
Parthenogenesis is a unique form of reproduction that refers to the fact that an oocyte can develop into a normal individual without fertilization,either spontaneously or through physical or chemical stimulation,without the involvement of sperm.In lower animals,parthenogenesis can be accomplished by females alone,thus enabling the production of offspring from a single female.In mammals,however,instances where parthenogenesis can develop into normal individuals are extremely rare.In this paper,we describe how parthenogenesis is activated,how parthenogenic embryos are acquired,and how imprinted genes are used in parthenogenesis,with a view to providing ideas for future applications of parthenogenesis.
