摘要
目的 : 在白色ICR小鼠建立B16细胞株黑色素瘤模型 ,以便于接种、测量和观察 ,既能降低研究成本 ,又能满足不同实验目的要求。 方法 :将B16细胞株黑色素瘤对数生长期细胞接种于ICR小鼠足垫、皮下、腹腔和尾静脉等部位 ,建立移植瘤模型和肺部转移瘤模型。观察小鼠成瘤特点 ,并作病理和免疫组化染色检查 ,分析接种细胞数与肿瘤生成的关系以及肿瘤生长对小鼠生活状态和生存时间的影响。 结果 :6天后白色小鼠浅表部位和深部脏器 (解剖后 )可陆续观察到芝麻样或点线状到结节状、菜花状黑色瘤组织 ,直到发展至溃烂和 (或 )小鼠死亡。成瘤率与接种细胞数成正比 ,在接种细胞数 >1× 10 6 后成瘤率为 10 0 %。 结论 :B16细胞株黑色素瘤在ICR小鼠具有成瘤率高、观察和测量方便、费用低等优点 。
Objectives: To establish melanoma models of B16 cell line in ICR mice. Methods: Inoculating B16 Melanoma cells in ICR mice's feet, back, abdomen and caudal vein, to establish transplanted and metastatic melanoma models. We observed the morphologic characteristics and examined the pathological parameters of melanoma. We analyzed the relations between the number of B16 cells inoculated and the genesis of tumors, the influence of tumor growth on mice's behavior,and growth curve of the melanoma. Results:Six days later, sesamoid, linear and nodal even kaulifloweroid melanoma were seen gradually in ICR mice's feet, back, abdomen and lung (anatomid) after inoculating. The bearing tumor rates have a positive relation to the number of inoculated B16 cells. The rates of bearing tumor was near 100%, after inoculating with 5×10 6 B16 cells. Conclusions: The B16 melanoma cell line derived from C57/B16 mice(black ) has high rates of bearing tumor in ICR mice (white). The B16 melanoma models in ICR mice are ideal tumor models that have the characteristics of easy established,easy observing and easy obtaining.
