使用小鼠模型的研究已经确定了常驻卫星干细胞在骨骼肌发育和再生中的关键作用,但对人类肌肉的这种模式知之甚少。在这里,我们使用人类肌肉干细胞来研究它们的谱系进展、分化、迁移和自我更新。分离的人卫星细胞表达α7-整合素和其他决定性的肌肉标志物,在层粘连蛋白底物上具有高度的运动性,可以进行有效的肌管分化和肌纤维形成。然而,只有一小部分成肌细胞表达Pax7,并且通过desmin和MyoD表达表现出可变的谱系进展。分析发现了一个具有分化抗性的祖细胞群,它是Pax7+/desmin -,能够自我更新。这项研究扩展了我们对pax7在调节人卫星干细胞分化和自我更新中的作用的理解。
Studies using mouse models have established a critical role for resident satellite stem cells in skeletal muscle development and regeneration but little is known about this paradigm in human muscle. Here using human muscle stem cells, we address their lineage progression, differentiation, migration and self-renewal. Isolated human satellite cells expressed α7-integrin and other definitive muscle markers, were highly motile on laminin substrates, and could undergo efficient myotube differentiation and myofibrillogenesis. However, only a subpopulation of the myoblasts expressed Pax7 and displayed a variable lineage progression as measured by desmin and MyoD expression. Analysis identified a differentiation-resistant progenitor cell population that was Pax7+/desmin− and capable of self-renewal. This study extends our understanding of the role of pax7 in regulating human satellite stem cell differentiation and self renewal.
