The Claim

Pericytes are significantly more abundant in asymptomatic carotid plaques (19% of ROI) than in symptomatic plaques (3.8% of ROI), and human pericytes in vitro secrete osteoprotegerin and undergo osteoblastic differentiation, which is associated with plaque stabilization through bone-like calcification and inhibition of osteoclast activity.

How it works
1 study reviewed
In plain English

Pericytes are found in higher numbers in stable carotid plaques than in unstable ones. In laboratory conditions, these cells produce osteoprotegerin and transform into bone-like cells, which correlates with reduced plaque breakdown through calcification and suppression of bone-resorbing cells.

See the scientific wording

Pericytes are significantly more abundant in asymptomatic carotid plaques (19% of ROI) than in symptomatic plaques (3.8% of ROI), and in vitro, human pericytes secrete osteoprotegerin and undergo osteoblastic differentiation, suggesting they may contribute to plaque stabilization through bone-like calcification and inhibition of osteoclast activity.

Why this might work

Pericytes in carotid plaques turn into bone-like cells and release a protein that blocks the cells responsible for breaking down bone. This causes mineral deposits to form in a stable, organized pattern instead of a weak, fragile one, making the plaque less likely to rupture.

  1. Study: Osteoprotegerin, Pericytes and Bone-Like Vascular Calcification Are Associated with Carotid Plaque Stability

    This study found that stable carotid plaques have way more pericytes—cells that can turn into bone-like cells and release a protein that stops bone breakdown—than unstable plaques. This suggests these cells help make plaques less likely to rupture.
