| Outline of Final Research Achievements |
The Ehlers-Danlos syndrome (EDS) is a heterogeneous group of heritable connective tissue disorders. In order to investigate the mechanism of subcutaneous hematoma in DD-EDS patient, in this project, we established DD-EDS specific iPS cells from three patients, and then induced the differentiation of vessel smooth muscle cells, examined the contratility function of them.
All the findings showed reduced contractile response to vasoactive agonists such as endothelin-1 and carbachol and fewer vessel tube-like structure formation in DD-EDS patient iPS-derived VSMCs. Therefore, we can conclude that the insufficient contractile properties of VSMCs and abnormal blood vessel formation might be some reasons of subcutaneous hematoma which repeatedly happened in DD-EDS patient.
