Ethylenediamine-N,N,N′,N′-Tetraacetic Acid Induces Parthenogenetic Activation of Porcine Oocytes at the Germinal Vesicle Stage, Leading to Formation of Blastocysts1

Abstract
The present study showed that treatment with a cell membrane-impermeable metal ion chelator, EDTA, of porcine oocytes at the germinal vesicle (GV) st
