Genome reprogramming during the first cell cycle in in vitro produced porcine embryos

I. Barnetova K. Okada

CZECH JOURNAL OF ANIMAL SCIENCE 55(2) 49-57 2010年2月 [査読有り]

Conflicting data still exist regarding the extent of paternal pronuclear DNA demethylation in one cell-stage mammalian embryos. Demethylation of paternal pronuclear DNA was observed in in vivo produced porcine zygotes, whereas in vitro produced em...

Viability, acrosome morphology and fertilizing capacity of boar spermatozoa treated with strontium chloride

Konosuke Okada Chiara Palmieri Leonardo Della Salda Irena Vackova

ZYGOTE 16(1) 49-56 2008年2月 [査読有り]

The positive effect of strontium ions (Sr(2+)) on sperm motility, capacitation and acrosome reaction has been demonstrated in the mouse, human, guinea pig and hamster. In the present study, we have evaluated the effect of Sr(2+) on the viability a...

DNA methylation pattern in pig in vivo produced embryos

Josef Fulka Helena Fulka Tomas Slavik Konosuke Okada Josef Fulka

HISTOCHEMISTRY AND CELL BIOLOGY 126(2) 213-217 2006年8月 [査読有り]

DNA methylation/demethylation pattern, determined by 5-methylcytosine (5-MeC) immunostaining, was evaluated in porcine "in vivo" produced embryos from zygote up to the blastocyst stage. In one-cell stage embryos, only the maternal pronucleus showe...

Loss of Rec8 from chromosome arm and centromere region is required for homologous chromosome separation and sister chromatid separation, respectively, in mammalian meiosis

Jibak Lee Konosuke Okada Sugako Ogushi Takashi Miyano Masashi Miyake Masakane Yamashita

CELL CYCLE 5(13) 1448-1455 2006年7月 [査読有り]

Chromosome separation in meiosis I is different from those in mitosis and meiosis II in that homologs separate from each other in the former while sisters do so in the latter. We show here that meiosis-specific cohesin subunit Rec8 in mouse oocyte...

Development of pig embryos after electro-activation and in vitro fertilization in PZM-3 or PZM supplemented with fetal bovine serum

K Okada Krylov, V R Kren J Fulka

JOURNAL OF REPRODUCTION AND DEVELOPMENT 52(1) 91-98 2006年2月 [査読有り]

The aim of present study was to optimize culture conditions for pig embryos. Initially, we evaluated three different basic culture conditions. When embryos from electro-activation (parthenotes) or in vitro fertilization (IVF-embryos) were cultured...
