Techniques, methods & infrastructure

Our research interests lie in the principles of extravillous trophoblast (EVT) differentiation and function. In addition, we focus on immunological aspects during early pregnancy.

We currently have four main areas of research:

  1. Polyploidization and gene copy number variations in EVTs of normal and complete mole placentas
  2. Characterization of the EVT-specific secretome
  3. Characterization of tissue-specific macrophage signatures in the placenta and decidua
  4. Vascular alterations, immune cell distribution and function in decidual and endometrial tissues of women suffering from idiopathic, recurrent pregnancy losses.

Moreover, we are currently interested to study the regulatory effect of placenta-derived EVTs on transcriptional and phenotypical variations within decidual macrophages. To this end, we aim to perform SLAM-seq based analyses of 2D and 3D placenta organoid co-culture systems. Finally, we are interested to determine placenta-specific, EVT-enriched, secreted factors with the potential to serve as prognostic marker signatures to predict placental pathologies during early pregnancy.
