我们用Urethane诱发的小鼠肺腺癌在裸小鼠皮下移植传代并研究了该肿瘤的生长及转移特性。此转移模型具有移植成功率高,生长迅速,血管血窦丰富,并有较高的自发肺转移倾向,浸润性强等特点。这对于研究肿瘤转移、浸润以及肿瘤血管生成具有一定意义。 We used Urethane-induced mouse lung adenocarcinoma to subcutaneously transplanted in nude mice and examined the tumor growth and metastasis characteristics. The transfer model has the characteristics of high success rate of transplantation, rapid growth, rich blood sinus, high tendency of spontaneous lung metastasis and strong infiltration. This is of significance for the study of tumor metastasis, invasion and tumor angiogenesis.
