Round Spermatid Nuclei Injected into Hamster Oocytes form Pronuclei and Participate in Syngamy1

1 Feb 1993

Abstract excerpt

Round spermatids are spermatogenic cells that have just completed meiosis. To discover whether nuclei of these haploid cells are genetically ready for fertilization, nuclei were individually injected into mature hamster oocytes via a microsurgical technique. In the majority of oocytes that were successfully injected and activated, spermatid nuclei transformed into pronuclei and underwent DNA synthesis. Ultimately...
