Research Abstract

扁平上皮癌の腫瘍性間質誘導が、浸潤を契機に実質細胞から間質細胞に移管される(スイッチング)のではないかという仮説をたて、これを証明するために扁平上皮癌細胞と線維芽細胞の共培養系を作製して、細胞外基質分子代謝を軸に検討し、口腔癌組織の結果と照合した.その結果、上皮内癌に相当する分離共培養では癌細胞側に、浸潤癌に相当する混合共培養では、線維芽細胞側にECM 産生の主体があり、間質誘導が扁平上皮癌浸潤によって開始することを証明し、この概念を病理診断の理論的背景として適用することに成功した.この結果、非浸潤性腫瘍の腫瘍細胞間隙の細胞外基質を腫瘍細胞によって産生される上皮内基質という概念でとらえることを提唱することになった.
