... Centrosome duplication Electrofusion Maturation division Meiosis Starfish Artificial parthenogenesis in starfish was pioneered in the early 1980s by Obata and Nemoto ( Obata and Nemoto,1984 ) and later, Washitani-Nemoto et al.( Washitani-Nemoto et al.,1994 ) found that suppression...

... allele type remained in the egg after meiosis. Also in tetrapioid embryos, generated by electrofusion of homozygous fertilized eggs from the two strains, both genomes seemed to be activated at the same time at day 4; here, however, the GPI-1BB allozyme remained predominant up to day 6. After removal...

... of cytochalasin B-induced tetraploid mouse embryos, no other researchers have achieved development of tetraploid embryos beyond the early postimplantation period. We now report advanced postimplantation development of tetraploid mouse embryos following electrofusion of blastomeres at the 2-cell stage...

... 1988 nuclear transfer electrofusion parthenote androgenote imprinting mouse embryo Over the past three years, nuclear transfer experiments have firmly established that the participation of both male and female gamete nuclei is essential for full-term development of mouse embryos...
