乳腺上皮成分被认为是由干细胞产生的,干细胞经历自我更新和分化。自我更新已被证明是由Hedgehog,Notch和Wnt途径和转录因子B淋巴瘤Mo-MLV插入区1(Bmi-1)调节。我们回顾有关乳腺干细胞存在的数据和调节这些细胞自我更新的途径。我们提出的证据表明,在干细胞/祖细胞的自我更新失调可能是乳腺癌发生的一个关键事件。如果“肿瘤干细胞”本身对目前的治疗方法具有抗性,那么靶向干细胞自我更新途径可能为乳腺癌治疗提供一种新的方法。
The mammary gland epithelial components are thought to arise from stem cells that undergo both self-renewal and differentiation. Self-renewal has been shown to be regulated by the Hedgehog, Notch, and Wnt pathways and the transcription factor B lymphoma Mo-MLV insertion region 1 (Bmi-1). We review data about the existence of stem cells in the mammary gland and the pathways regulating the self-renewal of these cells. We present evidence that deregulation of the self-renewal in stem cells/progenitors might be a key event in mammary carcinogenesis. If 'tumor stem cells' are inherently resistant to current therapies, targeting stem cell self-renewal pathways might provide a novel approach for breast cancer treatment.
