Fig. 1From: Circulating microparticles in severe pulmonary arterial hypertension increase intercellular adhesion molecule-1 expression selectively in pulmonary artery endotheliumCirculating MP counts are elevated in PAH rats. The number of MPs per microliter of platelet-free plasma was determined using flow cytometry. Compared to 8-week control rats, the number of circulating MPs is significantly greater in 8-week PAH rats. n = 5 * = p < 0.05Back to article page
