Dr. Hansen lab studies the interactions between satellite cells and the vasculature. Satellite cells are skeletal muscle progenitor cells that are known to play an important role in muscle repair after injury and adaptation to exercise. However, the Hansen lab focuses on a previously underexplored role of satellite cells in vascular growth. They have found that satellite cells, when activated, produced a number of chemoattractant growth factors that drive the migration of vascular smooth muscle and endothelial cells which in an important factor in the growth and development of blood vessels. This area is of particular interest in the context of peripheral artery disease (PAD), where patients suffer from ischemic tissue damage but treatment options are still limited. We
