    4T1是從410.4瘤株中未經(jīng)誘變篩得的6-硫鳥(niǎo)嘌噙抗性細(xì)胞株。當(dāng)注射到BALB/c小鼠中時(shí)，4T1自發(fā)產(chǎn)生高轉(zhuǎn)移腫瘤，可轉(zhuǎn)移到肺，肝，淋巴結(jié)和大腦，同時(shí)在注射部位形成始發(fā)灶。誘導(dǎo)轉(zhuǎn)移時(shí)不需要摘除始發(fā)灶。4T1細(xì)胞在BALB/c小鼠中的生長(zhǎng)與轉(zhuǎn)移特性與人體中的乳腺癌十分相近。這種腫瘤是人VI期乳腺癌的動(dòng)物模型。4T1-誘導(dǎo)的腫瘤在手術(shù)后及未手術(shù)情況下轉(zhuǎn)移的動(dòng)力學(xué)相近，可以用作手術(shù)后及未手術(shù)模型。跟其他腫瘤模型相比，由于4T1的抗6-硫鳥(niǎo)嘌噙特性，微小的轉(zhuǎn)移細(xì)胞團(tuán)(少到僅僅1個(gè))也可以在許多遠(yuǎn)端器官中檢測(cè)到。
