Abstract:

Following fertilization, the blastocyst has to complete two distinct steps to assure further development of pregnancy. After apposition it establishes a firm connection with the luminal epithelium of the endometrium (attachment) and subsequently enters the decidualizing stroma (invasion). If this step is not achieved successfully, fertility problems arise. Development of the placenta ensures an adequate supply of nutrients and gas between the mother and the fetus. Preeclampsia is a prevalent disorder arising from defects in the process of placentation. It is associated with an increase of maternal morbidity and mortality. Numerous attempts have been made in order to elucidate the etiology of the syndrome and identify women at risk.

The lack of reliable animal models has turned the attention to the development of in vitro assays, which could provide a better insight into the individual processes that will later trigger preeclampsia symptoms. In particular, 3D in vitro models more closely resemble the complexity of the extracellular environment. The choice of the scaffolding material should be done carefully as cell-matrix interactions are very often as important as cell-cell interactions for the correct attachment, proliferation and differentiation of cells.

The following review is aimed to provide a general overview of the scaffolds available for the in vitro modeling of these complicated systems as well as to discuss the importance surrounding the choice of the scaffolding material and its influence on the results obtained.

Keywords: 3D in vitro models, early pregnancy, scaffolds, biomaterials, decidualizing stroma, endometrium.
