Interspecific chimeras have been produced by nuclear transplantation inDrosophila. The following species were used:Drosophila melanogaster, D. simulans, D. mauritiana, D. teissieri, D. yakuba, D. erecta andD. ananassae.Nuclei transplantated into fertilized eggs were able to multiply in a foreign cytoplasm and heterologous cells become integrated into the embryo to give viable adult chimeras.The morphological pattern of differentiation was autonomous both from that of the host and donor. In some cases, a possible non-compatibility between nuclei and cytoplasm has been postulated to explain the lack of chimeras.
通过核移植在果蝇中产生了种间嵌合体。使用了以下物种:黑腹果蝇、拟暗果蝇、毛里求斯果蝇、泰氏果蝇、雅库布果蝇、直立果蝇和阿纳萨果蝇。移植到受精卵中的细胞核能够在异源细胞质中增殖,异源细胞整合到胚胎中,从而产生有活力的成年嵌合体。分化的形态模式与宿主和供体的形态模式都是自主的。在某些情况下,有人假定细胞核与细胞质之间可能存在不相容性,以解释嵌合体的缺失。
