Haploid embryonic stem cells (haESCs) have been recently generated from parthenogenetic (PG) or andro- genetic (AG) blastoeysts of different mammals, including mouse, rat and monkey, enabling genetic screening a...
This study was conducted to investi- gate the pattern of DNA methylation in pronuclearstage mouse embryos derived from vitrified-warmed oocytes. Mouse oocytes at metaphase II (MII) stage of meiosis were allocated ra...
After the third prezygotic division during conjugation of Paramecium caudatum,migratory and stationary pronuclei are produced.The migratory pronuclei remain in the paroral region tightly against the conjugating bounda...

A cell-free system based upon the egg extracts from gynogenetic gibel carp (Carassius auratus gibelio)or bisexual red common carp (Cyprinus carpio red variety) was developed to investigate developmentalbehaviors of th...
Objective To determine the function of, in vivo, renin and its role in the pathogenesis of hypertension. Methods A renin 2 gene restriction map was constructed by endonuclease digest ion and Southern blotting hy...
The chronological and morphological changes of the nucleus during mouse oocyte maturation and fertilization were systematically studied. Although most oocytes went through GVBD 2-4 hrs after culture, 13.6% remained at...
