Systemic hormones are key regulators of postnatal mammary gland development and play an important role in the etiology and treatment of breast cancer. Mammary ductal morphogenesis is controlled by circulating hormones, and these same hormones are also critical mediators of mammary stem cell fate decisions. Recent studies have helped further our understanding of the origin, specification, and fate of mammary stem cells during postnatal development. Here we review recent studies on the involvement of hormone receptors and several transcription factors in mammary stem/progenitor cell differentiation and lineage commitment.
全身性激素是出生后乳腺发育的关键调节因子,在乳腺癌的病因学和治疗中发挥重要作用。乳腺导管形态发生受循环激素控制,而这些相同的激素也是乳腺干细胞命运决定的关键介质。最近的研究有助于我们进一步了解出生后发育过程中乳腺干细胞的起源、特化和命运。在这里,我们综述了关于激素受体和几种转录因子参与乳腺干/祖细胞分化和谱系定向的最新研究。
