Effect of Estradiol and Nonylphenol on mRNA Levels of VitellogeninII in the Liver of Chicken Embryos
nonylphenol estradiol vitellogenin II chicken embryo RT-PCR
2009/8/3
Nonylphenol is one of the endocrine disrupting agents with estrogenic activity in some vertebrates. The present study was conducted to assess estrogenic activity of p-nonylphenol (NP) in chicken embry...
Population of Circulating Primordial Germ Cells in Early Japanese Quail Embryos
primordial germ cells circulation erythrocytes quail embryo
2009/8/3
Avian primordial germ cells (PGCs) show a unique migration pathway during early development. As soon as the blood vessels have formed, PGCs enter the circulatory system, and migrate to the gonadal pri...
Fate of the Donor Blastodermal Cells Derived from the Central Disc,Marginal Zone and Area Opaca Transferred into the Recipient Embryos
chicken blastodermal cell GFP gene gene expression lipofection
2009/8/3
In order to trace the donor blastodermal cell movement in the recipient embryos, stage X blastodermal cells derived from the central disc (CD), marginal zone (MZ) and area opaca (AO) were transfected...
