The growth of 6 different human melanomas xenografted into athymic mice was followed by measuring 2 vertical diameters twice weekly. The growth rate of the xenografts was expressed as the tumour doubling time, measured in the volume range 30-60 mm3. None of the xenografts increased their growth rate with increasing number of passages. The tumour lines, which were histologically very similar, showed individual, characteristic growth rates differing by a factor of 3. Evidence was obtained that resistance to cytostatic drugs in the patients is retained in the xenograft. Procedures for evaluating response to chemotherapy are discussed.
将6种不同的人类黑色素瘤移植到无胸腺小鼠体内,通过每周两次测量两个垂直直径来跟踪其生长情况。异种移植物的生长速率用肿瘤倍增时间表示,在30 - 60立方毫米的体积范围内进行测量。没有一种异种移植物随着传代次数的增加而提高其生长速率。这些组织学上非常相似的肿瘤系显示出各自独特的生长速率,相差3倍。有证据表明,患者对细胞抑制药物的耐药性在异种移植物中得以保留。文中讨论了评估化疗反应的程序。
