背景描述 |
MCF7细胞是人类乳腺癌研究中广泛使用的研究模型,被广泛用作激素依赖性乳腺癌的体外模型。MCF7细胞起源于一名患有转移性腺癌的69岁白人女性的乳腺组织,是一种广泛用于激素依赖性乳腺癌的体外模型,反映了LuminalA亚型。与更具侵袭性的乳腺癌相比,该亚型的特征是分级较低,预后较好。 |

核型 |
modal number = 82; range = 66 to 87.The stemline chromosome numbers ranged from hypertriploidy to hypotetraploidy, with the 2S component occurring at 1%. There were 29 to 34 marker chromosomes per S metaphase; 24 to 28 markers occurred in at least 30% of cells, and generally one large submetacentric (M1) and 3 large subtelocentric (M2, M3, and M4) markers were recognizable in over 80% of metaphases. No DM were detected. Chromosome 20 was nullisomic and X was disomic. |
