| Outline of Final Research Achievements |
We succeeded the development of xenogragt model of hepatocellular carcinoma (HCC) by ultrasonography(US)-guided implantation of human HCC cell line "hepG2" into the liver parenchyma of immunodeficienct pigs. We demonstrated angiography and contrast CT scan after confirming the engraftment of tumor by US and early enhancement and washout were observed, which was compatible with human HCC. Furthermore, the engrafted tumor was pathologially compatible with poorly to moderately differentiated HCC. This model can be applied to develpment of novel treatment modality for human HCC or evaluation of efficacy of current treatments.
