Welcome


Welcome to the website of our research laboratory for reproductive biology and placenta immunology!

 

The placenta is a completely transient 5 in 1 organ. It performs the actions of the lungs, kidneys, liver, intestines and glands. All in order to ensure a proper metabolic supply of the fetus.

A normally developed and functioning placenta is essential for the growth and development of the fetus. A poorly developed placenta is often associated with higher perinatal morbidity and mortality caused by preterm delivery, pre-eclampsia and other severe pregnancy associated disorders. The development of a haemochorial placenta involves the invasion of extravillous trophoblast cells into the uterine wall and the remodelling of the uteroplacental vessels. (Zygmunt 1998)

During pregnancy, immune homeostasis is crucial for pregnancy maintenance. Local and systemic immune adaptations facilitate the implantation and later the accommodation of the growing fetus. These adaptations include the promotion of uterine vascular remodeling and the induction of immune tolerance. Both maternal lymphocytes and fetal derived cells including trophoblast establish a complex interaction to balance the inflammatory environment providing protection against pathogens and the necessary cytokine milieu that allows local structural modifications during placentation. (Heusler 2021)

The unfulfilled wish for a child affects many couples. A common reason for this is a proximal tubal occlusion. In close cooperation with the Institute for Implant Technology and Biomaterials e.V. and the University of Rostock, we are working on the development of a fallopian tube stent to enable a natural pregnancy.

 

Yours sincerely,

Damián Muzzio and Marek Zygmunt

Congress of the Society of Reproductive Investigation (SRI) in Vancouver 2024

Once again we attended the Congress of the Society for Reproductive Investigation (SRI) this year. In beautiful Vancouver, Canada, we used the time to exchange ideas with colleagues and discuss the latest developments in reproductive medicine. As always, it was a great experience.
