SNAI2 and pemphigus foliaceus: Therefore, we developed a new animal model, by sequential administration of bleomycin and MCT in rats, that better recapitulates the histological differences (vascular remodeling in both fibrotic and non‐fibrotic areas) and molecular differences (Slug and PIP upregulation) observed in our PF‐PH patients (Figs 4 and 5).
