Abstract

A type I interferon resistant variant (beta-MIP101) of the poorly differentiated human colon cancer cell MIP101 has a more aggressive phenotype in vivo in the nude mouse. Subcutaneous tumours grew at twice the rate of MIP101, but with similar morphology. beta-MIP101 also produced liver metastases at a higher frequency. beta-MIP101 tumours were diploid while MIP101 tumours were aneuploid. Both cell lines had doubling times of approximately 25 h in vitro.

摘要

低分化人结肠癌细胞MIP101的I型干扰素抗性变体(β-MIP101)在裸鼠体内具有更具侵袭性的表型。皮下肿瘤生长速度是MIP101的两倍,但形态相似。β-MIP101产生肝转移的频率也更高。β-MIP101肿瘤为二倍体,而MIP101肿瘤为非整倍体。两种细胞系在体外的倍增时间均约为25小时。
