| Outline of Final Research Achievements |
Cultured cells were obtained from arteriovenous malformation specimens obtained from surgical specimens. RNA extracted from these cells was comprehensively examined by microarray and further immunohistochemical study showed higher expression of selectin-P (SELP) than human normal artery-derived endothelial cells and human umbilical vein-derived endothelial cells. In refluxing culture, the growth of the cultured cells did not spread in the flow direction of the culture medium, but rather grew in a reverse manner. SELP seemed to have the high possibility of being concerned in the abnormal blood vessel breeding of AVM of the body surface. It was proven that the flow had some effects on the cell proliferation, because the cell proliferated against the flow of the culture solution.

| Academic Significance and Societal Importance of the Research Achievements |
動静脈奇形は臨床上治療困難とされる脈管奇形の一つであり，今回の結果でその増殖因子の一つが解明でき，薬物療法を含めた治療法の開発に寄与できる可能性がある．また流動刺激に逆行して細胞が増殖していたことから，血流をコントロールすることで増殖を抑制できる可能性が示唆される結果となり，これについても治療に応用できる可能性が示された．
