| Outline of Final Research Achievements |
Proper formation of the heart and blood vessels is achieved by the combinatory functions of various cellular molecules. Among those, transcription factors play central roles in regulating when, where and how much those functional molecules are produced. We previously identified the Hrt/Hey family of transcription factors and reported their significance during cardiovascular differentiation (acquirement of proper cell characteristics) and morphogenesis (construction of functional architecture). By using Hrt/Hey deficient model mice and molecular biological techniques in this study, we further demonstrated that the functions of Hrt/Hey in endothelial cells were essential for embryonic vascular formation.
