Aging, CVD risk factors and progenitor cells

Cardiologists Ibhar Al Mheid, Arshed Quyyumi and colleagues from Emory’s Clinical Cardiovascular Research Institute recently published a paper that weaves together insights from past research on circulating progenitor cells. They tease apart the influences of age and cardiovascular disease (CVD) risk factors on these cells, whose regenerative capacity has made them the target of much investigation. From this research, one can infer that the circulatory system has a limited regenerative capacity, and stress upon the system earlier in life depletes it later.

Circulating progenitor cells are rare cells in the blood that can become white or red blood cells, as well as endothelial cells, which line blood vessels and repair them when damaged by cardiovascular disease. Quyyumi and his colleagues have sought to deliver progenitor cells, derived from the patient’s own bone marrow, to the heart – or less invasively, spur them out of the bone marrow with drugs.
