Proximal Pulmonary Artery Stiffening as a Biomarker of Cardiopulmonary Aging
To investigate cellular and molecular mechanisms associated with the age-related remodeling observed in the proximal pulmonary artery, we analyzed transcriptomic changes of resident pulmonary arterial cells. Overall design: Proximal pulmonary arteries were excised from young and aged mice and analyzed using scRNAseq.
