摘　　要：This paper reports the development of the nuclear transplanted eggs obtained by transplanting Xenopus laevis blastomere nuclei to Bufo raddei. The formation of the donor nuclei is similar to that of the male pronuclei in the normal development egg in the early stage while shows degradation in the late stage after transplanting. The chromosome complement formes in some eggs 30 minutes after transplantation, which is assumed to contribute to the development of the transplanted eggs.This paper reports the development of the nuclear transplanted eggs obtained by transplanting Xenopus laevis blastomere nuclei to Bufo raddei.
