Somatic Cell Cloning without Micromanipulators
1 Jun 2001
Abstract excerpt
Until now, micromanipulators have been regarded as indispensable for somatic cell nuclear transfer. This paper describes an improved zona-free nuclear transfer procedure with manual bisection of oocytes, selection of cytoplasts by Hoechst staining, and two-step fusion of somatic cells from primary granulosa cell cultures with two cytoplasts. Blastocyst rates in the three systems tested for zona-free embryo...
