Abstract 105: Smooth Muscle Cell-derived Vascular Progenitor Cells Promote Arterial Remodeling and Fibrosis Through Loss of Hedgehog/Wnt/β-catenin/Klf4 Activity

Resident vascular adventitial progenitor cells express the stem cell marker, Sca1 (AdvSca1 cells). Using smooth muscle cell (SMC) lineage tracing models and YFP reporter knock-in, we identified a s...
