CD34+ progenitors are predictive of mortality and are associated with physical activity in cardiovascular disease patients (2021)
Journal Article
Muggeridge, D., Dodd, J., & Ross, M. D. (2021). CD34+ progenitors are predictive of mortality and are associated with physical activity in cardiovascular disease patients. Atherosclerosis, 333, 108-115. https://doi.org/10.1016/j.atherosclerosis.2021.07.004

Background and aims Circulating progenitor cells (CPCs) play an important role in vascular repair and can influence cardiovascular (CV) health and longevity. Exercise is known to modulate these cells via mobilization from the bone marrow. The primar...
