| Outline of Final Research Achievements |
We constructed a microfluidic system that enabled us to analyze the function of human placental barrier under the fluid flow microenvironment. We used a human trophoblastic cell line, human umbilical vein endothelial cells and a vitrified collagen scaffold to reconstruct the polarized multi-layered barrier structure between two microfluidic channels. Using our device, we found that fluid flow induced the formation of microvilli in the placental barrier construct, as observed in the placental barrier tissue, whereas static culture failed to induce microvilli. Fluid shear stress also affected the material transfer through the barrier constructs. We further revealed that the microvilli are induced via a mechanosensitive activation of TRP channel.
