乳腺癌是女性常见的癌症类型之一,长期以来科学家们知道并不是所有的乳腺癌都是相似的,腔体肿瘤主要包含一些和乳腺管内层细胞非常相似的细胞类型,而其它肿瘤所包含的细胞则同乳腺上皮组织外层的细胞相似,研究者认为,这种多样性起源于不同干细胞或祖细胞的突变,而目前研究人员也并没有完全理解这些特有的祖细胞群体的身份和其形成肿瘤的能力。
Breast cancer is one of the common types of cancer in women. For a long time, scientists know that not all breast cancers are similar. Cavity tumors mainly contain some cell types that are very similar to those of breast duct lining cells, while other tumors contain The cells are similar to those in the outer layer of the mammary gland epithelium. Researchers believe this diversity stems from mutations in different stem or progenitor cells. At present, researchers do not fully understand the identity and formation of these specific progenitor populations Tumor ability.
