Workshop "The precosity of mammals"
The workshop "The precosity of mammals" will be held on the 24th of October at 12:00.
Lecturer - Elena Lavrentieva
Subject: The dynamics of germinal vesicle and nucleolus in preovulatory ovocytes of a mouse.
On the ground of a common configuration of chromatin, preovulatory (GV) ovocytes of mammals are divided into two main types (NSN and SN). It’s generally thought that a mouse's SN-ovocytes are more competent because they alone can get embryos, can invitro develop to blastocyte. The location of a germinal vesicle and nucleoloid bodies is another measure of the ovocytes' competence over the ripening. For the moment, the connection between the location of a germinal vesicle and the configuration of chromatin with the mouse ovocytes' capacity over the ripening is the one of the key issues of embryology, which is caused by the necessity of improvement of reproductive technologies. Laws of behaviour of predecessors of germinal vesicles and nucleoles in the ovogenesis and in the embryogenesis will be examined in the lecture.
