Why stem cell numbers decline with age is a major question in regenerative biology and medicine. Skeletal muscle has emerged as a powerful paradigm to address this issue. Recently, genetic and cell marking strategies were used to uncover a new and causal relationship between muscle stem cells and differentiated fibers that constitute their niche and provoke their loss.
为什么干细胞数量会随着年龄的增长而减少,这是再生生物学和医学中的一个主要问题。骨骼肌已成为解决这个问题的有力范例。最近,遗传和细胞标记策略被用来揭示肌肉干细胞与其构成其生态位并促使其丧失的分化纤维之间的一种新的因果关系。
