Team of scientists from Münster discovers important principle to examine different culture media for in vitro fertilisation
August 15, 2017
Reproduction medicine is a booming business; the number of fertility treatments is continuously growing – firstly, because couples postpone their decision in favour of children, but also because taboos on assisted reproduction are breaking. To further improve assisted reproduction, basic research in animal models is indispensible. A team of scientists from the Max Planck Institute for Molecular Biomedicine and the Centre of Reproductive Medicine and Andrology of the University of Münster has now discovered in early mouse embryos that the first two cells, which arise after the first cleavage of the fertilised egg, are not equal in most cases. These differences question the scope of totipotency and offer the opportunity to investigate how culture media that are used in fertility clinics influence embryo development.
