Ivanov "Ascania-Nova" - National Scientifical Selectional-Genetics Center of Sheep Breeding popup.description2 Object of research - the regularities of influence of protein, hormonal and energetic substances on oo- and early embryogenesis in mammals, the speed of blastomeres dissociation and cavitation in early embryos of different origins in sheep and mouse. Purpose of research - the investigate of features action of protein, hormonal and energetic substances on oo- and ear-ly embryogenesis in mammals, functionality and character of placement of intercellular contacts in early mammalian embryos made and cultured in different condition, to work out the scientific concept of mechanism of compactization in early mammalian embryos, to improve the some stages of method of reception of embryos after oocyte in vitro cul-ture. Research methods - culture in vitro, microscopy, cytogenetic analysis, statistic and correlative analysis, dialectic and comparative methods of the data analysis. The influence of protein, hormonal and energetics substances on oo- and early embryogenesis in mammals had been investigated, the dependences of duration of dissociation of embryos on blastomeres from ways of reception and composition of culture mediums had been calculated, the state of a scientific concept of mechanism of compactiza-tion and cavitation in early mammalian embryos had been postulated, methodic aspects of procedure production of sheep and mouse in vitro embryos had been expounded. Field of using - biology of reproduction, reproductive biotechnology. Product Description popup.authors Жулінська Оксана Степанівна Лобачова Ірина Вікторівна popup.nrat_date 2020-04-02 Close
