Production of Nuclear Transfer Horse Embryos by Piezo-Driven Injection of Somatic Cell Nuclei and Activation with Stallion Sperm Cytosolic Extract1
1 Aug 2002
Abstract excerpt
We investigated the use of direct nuclear injection using the Piezo drill and activation by injection of stallion sperm cytosolic extract for production of cloned equine embryos. When metaphase II horse oocytes were injected with either of two dosages of sperm extract and cultured 20 h, similar activation rates (88% vs. 90%) and cleavage rates (49% vs. 46%) were obtained. The successful reconstruction rate of...
