| Outline of Final Research Achievements |
The purpose of this study was to investigate the role of midkine in the progression of aortic stenosis (AS). From the preparation after operation of AS, the existence of midkine was confirmed in valve interstitial cell (VIC) by HE-stain and immnostaining of midkine. Next, in many preparations of aortic valve from autopsied patients showed the existence of midkine. In many patients who showed the staining of midkine without AS had malignancy or severe infectious disease.
We, next, investigated the expression of mRNA of midkine using RT-PCR method, but the density of VIC in the valve was too low to identify the mRNA of midkine, because of severe calcification of the valve.
