| Outline of Final Research Achievements |
To reveal novel roles of LPA4 and LPA6 in embryonic blood vessel formation, LPA4-deficient mice were crossed with LPA6-deficient mice to generate the double mutants. Mouse embryos at different developmental stages were macroscopically observed. At embryonic day (E) 9.5-10.5, almost all of the LPA4/LPA6-double deficient mice had some morphological abnormalities, such as severe pericardial effusion, developmental delay, poor vascular network in head and intersomitic regions and enlarged dorsal aorta. Furthermore, the yolk sacs of LPA4/LPA6-double deficient lacked large vessels.. Of note, all double mutants died by E11.5.
