Research interests

“Science is the search for truth that is the effort to understand the world.” (L. Pauling)

In placental research, the “truth” of a series of processes that takes place at the fetal-maternal interface, and that is a prerequisite for a successful pregnancy outcome, still needs to be unraveled. In detail, the fetal placenta anchors with its villous tree to the maternal uterine tissue, referred to as decidua. Afterward, precisely controlled differentiation processes give rise to proliferative cell columns, which differentiate into highly invasive extravillous trophoblasts (EVTs) at their distal end. These cells penetrate the decidua and fulfill fundamental functions (e.g., invasion/ remodeling of vessels and glands, secretion of pregnancy-related factors, and interaction with immune cells). Importantly, defective EVT functions are associated with severe pregnancy complications (e.g., recurrent spontaneous abortion [RSA], preeclampsia, and intrauterine growth restriction). Hence, the overall goal is to identify the mechanisms that underlie abnormal placental development and function and to transfer these findings into clinically useful tools to improve pregnancy outcomes.

Currently, my research interests encompass two issues:

1. The interaction of decidual vessels and immune cells in healthy pregnancies vs. idiopathic RSA 

2. EVT-derived secretome to identify diagnostic markers for pregnancy complications

 

Techniques, methods & infrastructure

  • Primary cell culture of human trophoblasts, trophoblastic cell lines, villous explant culture model systems, trophoblast organoids
  • various biochemical, cell biological and imaging techniques (e.g., immunofluorescence of sections  and cells, western blot, RNA interference, semi-quantitative/real-time PCR, ELISA, flow cytometry and laser-captured microdissection)
  • Clinical Research
