| Outline of Final Research Achievements |
[Purpose] H19 is maternally imprinted long non-coding RNA and also serves as a precursor for miR-675. Even though both are highly expressed in the placenta, expression cell types are still not reported. This time, we analyzed expression of H19 and miR-675-3p in mice term placenta.[Methods] Total RNA extracted from B6D2F1 placenta (E7.5~E18.5) was used for expression of H19 and miR-675. Expression positive cells were identified by in situ hybridization (ISH) using E18.5 placenta.[Results] By ISH at E18.5 labyrinth, H19 was expressed in fetal vascular endothelial cells and mononuclear trophoblasts, but not in syncytio trophoblasts. But miR-675-3p was positive in all placental barrier constituent cells. In addition, miR-675-3p was also positive in H19 negative spongy trophoblasts in the junctional zone.[Conclusion] This is the first report that miR-675-3p produced from H19 expressing cells was secreted to nearby H19 negative cells and need further investigation for detail functions.
