The magic of a new beginning: how an oocyte becomes an embryo

Precongress Course 2

 Special Interest Group Embryology


Course coordinators
Susanna Apter (Finland), Giovanni Coticchio (Italy), Yves Guns (Belgium), Monica Marques (Portugal), Debbie Montjean (France), Sophie Debrock (Belgium), Ioannis Sfontouris (Greece), Roger Sturmey (United Kingdom), Leonie Van Den Hoven (The Netherlands)

 

Course type
Advanced


Course description
The course will consider the molecular, nuclear, biochemical and cellular changes that occur as an oocyte develops into an embryo. In particular, the programme will cover crucial aspects of oocyte-embryo transition, such as changes in cell design, regulation of meiosis and mitosis, maternal control and zygotic gene activation, energy in oocytes and embryos and mechanisms of self-correction as the blastocyst is formed.
 

Target audience
Clinical embryologists, biotechnologists and reproductive specialists

 

Educational needs and expected outcomes

Oocytes and embryos represent a continuum that, is finely co-ordinated to achieve preimplantation development. However, such dynamic development presents major challenges to cell regulatory mechanisms. Although the oocyte provides the majority of the buiding blocks required to design a fully developed blastocysts, the maternal cellular, metabolic and molecular legacies are subject to extensive rearrangements and regulation to respond to the embryo's evolving developmental needs. Further optimization of oocyte and embryo development in vitro depends on a deep understanding on such regulatory mechanisms, in order to maximize the chances of implantation and establishment of a full term pregnancy.
