MicroRNA profiling of human glioblastoma cell line U87 cell spheroids before and after migration on collagen

U87 cell spheroids were harvested from collagen on day 0 (no migration), or day 3 (extensive migration). The RNA extracted from these cells was used to identify microRNA alterations that occur during glioma cell line migration.

U87细胞球（U87 cell spheroids）于第0天（无迁移状态）或第3天（发生广泛迁移）时从胶原中收获。从上述细胞中提取的RNA被用于鉴定胶质瘤细胞系迁移过程中出现的微小RNA（microRNA）表达改变。
