    Abstract

    Pericytes Contribute to Pulmonary Vascular Remodeling via HIF2α Signaling

    Using single-cell RNAseq and hypoxia-induced pulmonary hypertension models, researchers showed that hypoxia-inducible factor 2α (HIF2α) was a major molecular regulator for the transformation of pericytes into smooth muscle cell-like cells.
