我们检查了 C57Bl/6J 小鼠中同基因小鼠黑色素瘤的眼部转移,并比较了体内维持的 B16F10 肿瘤细胞与培养中维持的 B16F10 肿瘤细胞的转移能力。我们证明,只要肿瘤细胞来自体内,眼内肿瘤就很容易转移到肺部。当体内来源的肿瘤作为前房内 (ic) 细胞悬浮液或作为植入虹膜上的固体片段引入时,100% 的动物在 5-6 周后因广泛的肺转移而死亡。相反,当B16F10细胞在培养物中传代五次并接种ic时,可以看到转移的频率和程度显着降低,并且存活率增加。这些研究证明培养的 B16F10 细胞从眼睛转移的能力发生了变化。当将来自眼睛的体内肿瘤转移与来自眼外位置的转移进行比较时,肺转移的程度和频率以及宿主的存活率是相同的。之前仅使用培养细胞检查了去核对 B16F10 从眼睛转移的影响。在本文中,我们证明去核的功效取决于 B16F10 黑色素瘤细胞是否在体内或体外传代。
We examine ocular metastasis of syngeneic murine melanoma in C57Bl/6J mice and compare the metastatic capability of B16F10 tumor cells maintained in vivo with those maintained in culture. We demonstrate that as long as the tumor cells are derived from an in vivo source, intraocular tumor readily metastasizes to the lungs. When in vivo derived tumor is introduced as an intracameral (ic) cell suspension, or as a solid fragment implanted on the iris, 100% of the animals die with extensive pulmonary metastasis 5-6 weeks later. In contrast, when B16F10 cells are passaged five times in culture and inoculated ic, a marked decrease in the frequency and extent of metastasis, and an increase in survival is seen. These studies demonstrate an alteration in the ability of cultured B16F10 cells to metastasize from the eye. When metastasis of in vivo derived tumor from the eye was compared with metastasis from an extraocular location, the extent and frequency of pulmonary metastasis and survival of hosts was the same. The effect of enucleation on the metastasis of B16F10 from the eye has only previously been examined using cultured cells. In this paper, we demonstrate that the efficacy of enucleation depends upon whether B16F10 melanoma cells have been passaged in vivo or in vitro.
