human studies indicate that aging is associated with an increase in
somatic mutations in the hematopoietic system, which gives rise to blood
cells; these mutations provide a competitive growth advantage to the mutant hematopoietic
cells, allowing for their clonal expansion — a process that has been shown to be associated with a greater incidence
of atherosclerosis, though specifically how remains unclear.
