| Outline of Final Research Achievements |
Purpose of our research is to elucidate possible mechanism of maternal vascular remodeling by extravillous trophoblast (EVT) that takes place at human implantation sites. Here, we demonstrated that both CD9 and CD59 are highly and specifically expressed on EVT invading maternal vessels (eEVT). Accordingly, functional experiments were carried out using immotile EVT cells (Swan71) and choriocarcinoma cell line (BeWo).
As for CD9, knock down of this molecule inhibited lumen formation in Swan71, suggesting that CD9 is involved in the replacement of maternal endothelium by eEVT. As for CD59, we found that Swan71 but not BeWo expresses this molecule, and further experiments are currently in progress.
