The goal of the research in my laboratory is to understand the molecular regulatory pathways that control proliferation and differentiation of stem cells during regeneration and underlying molecular mechanisms in stem cell dysfunction related to aging or degenerative diseases. Our current research is focused on the elucidation of regulatory mechanisms and in vivo function of key stem niche signals (Sonic hedgehog and Wnt), cell adhesion molecules and protein arginine methyltransferases by utilizing knockout mice, disease animal models and stem cells as model systems. The long-term goal of this research is to identify molecular targets for the development of therapeutic tools to intervene the aging-related muscle atrophy, cardiovascular diseases or degenerative diseases.
