Demecolcine-induced oocyte enucleation for somatic cell cloning: coordination between cell-cycle egress, kinetics of cortical cytoskeletal interactions, and second polar body extrusion.

Abstract excerpt

Studies were designed to further explore the use of pharmacological agents to produce developmentally competent enucleated mouse oocytes for animal cloning by somatic cell nuclear transfer. Metaphase II oocytes from CF-1 and B6D2F1 strains were activated with ethanol and subsequently exposed to demecolcine at various times postactivation. Chromosome segregation, spindle dynamics, and polar body (PB) extrusion...
