Tissue: Brain; Derived from metastatic site: bone marrow. Modal number = 44, XX; Most cells were monosomic for chromosomes 10, 11, 13, 14 and 19; All cells were missing both copies of chromosome 2; Five marker chromosomes of unknown origin were observed in each cell. One of the marker chromosomes contains a homogeneously staining region (HSR); No double minutes were seen. 组织:脑;来源于转移部位:骨髓。模态数 = 44, XX;大多数细胞在 10、11、13、14 和 19 号染色体上是单体的;所有细胞都缺失了 2 号染色体的两个拷贝;在每个细胞中观察到五个来源不明的标记染色体。其中一个标记染色体包含一个均匀染色区(HSR);没有看到双分钟。
