Understanding the cellular cues that direct muscle stem cell specification

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.
