Understanding the cellular cues that direct muscle stem cell specification

该项目的目的是确定调节肌肉干细胞特性的代谢因素，并研究局部代谢环境的变化如何影响干细胞对生物扰动的反应。骨骼肌生物学中最重要和最悬而未决的问题之一是了解肌肉干细胞在生长发育、适应和可塑性调节中的作用。我们已经证实局部骨骼肌代谢环境可能调节骨骼肌干细胞的活性。该项目可能揭示骨骼肌干细胞可以被调控的新机制。这些信息对于我们对干细胞生物学及其未来应用的基本理解至关重要。

The project aims are to identify the metabolic factors that regulate muscle stem cell identity and to examine how changes in the local metabolic environment can influence how stem cells respond to biological perturbations. One of the most important and unresolved issues in skeletal muscle biology is understanding the role of muscle stem cells in the regulation of growth and development, adaptation and plasticity. We have identified that the local skeletal muscle metabolic milieu may regulate the activity of skeletal muscle stem cells. This project could reveal novel mechanisms by which skeletal muscle stem cells can be regulated. This information is crucial for our fundamental understanding of stem cell biology and its future applications.
