| Outline of Final Research Achievements |
A placenta-on-a-chip was developed in this study in order to reproduce the structure and function of the microenvironment of a human placenta. Media channels, which model intervillous space and fetal blood vessel, were placed flanking the three parallel gel channels which mimic the extracellular matrix. Gas channels through which gas mixtures are supplied to control the oxygen tension inside the chip were placed above the media channels. A method to form monolayers of human choriocarcinoma cells (JEG3s) and human umbilical vein endothelial cells (HUVECs) in the media channels, and a method to measure the permeability of the monolayers were established. The co-culture of JEG3s and HUVECs under a controlled oxygen tension at different concentrations showed variations of cell morphology and cell junctions, implying that oxygen tension can influence the cell-cell interaction.
