| Research Abstract |
Fetus develops mineralized bones during very last days of pregnancy. However, the molecular mechanism of the mineral transport has still been unclear. In an attempt to the molecular identification of the maternal-fetal mineral transport during fetal bone formation, I found TRPM6 as a candidate mineral entry pathway. TRPM6 was mainly localized in the intraplacental yolk sac, which is thought to be the place for the maternal-fetal mineral transport, and its expression was significantly increased during the last 4 days of pregnancy, which coincides with the fetal bone formation in mice. Moreover, TRPM6-like activity was observed in a cell line derived from human placental trophoblasts. These results suggest that TRPM6 plays an important role in the maternal-fetal mineral transport in order to sustain fetal bone formation.
