小鼠软脑膜黑色素瘤原位模型的建立及其在评价脑肿瘤疫苗中的应用
发布时间:2023-08-11 19:55
软脑膜黑色素瘤(LMM),从颅外黑色素瘤的转移灶或从本有的黑色素细胞开始发展,在预后差的黑色素瘤患者中,有22%的发病率。在本实验研究中,我们建立了一个小鼠大脑LMM模型,在C57BL/6小鼠的头骨上打孔,使用一个自我改良的微量注射器将B16细胞直接注入到蛛网膜下腔。35%至40%的小鼠大脑或大脑和小脑延髓池浸润黑色素瘤,.10%的小鼠大脑或小脑浸润,15%的小鼠枕大池和脊髓浸润。黑色素瘤在大脑半球的表面形成了一个约1.5×1.3×1.0厘米大小的黑色胶状团块,有多处隆起并聚集的小瘤块。在脑基底部的柔脑膜、大脑和脊髓无可见黑色素瘤。组织病理学检测可见黑色素瘤组织充满B16细胞且血管生长迅速,脑组织无黑色素瘤细胞,黑色素细胞广泛地渗透在软脑膜层。在临床上,在小鼠身上发现的肿瘤位置和可检测的症状的相关性,在患者LMM是同样适用的。为了测试的小鼠模型的可行性,我们也尝试了用肿瘤细胞B16裂解物(TCL)免疫LMM模型小鼠去诱导抗LMM免疫。
