Figure Lengend Snippet: Depletion of pulmonary BMPRII‐short and long fragments in humanized BMPR2 +/R899X mutant mice caused vascular remodeling independent of pulmonary caveolin‐1 expression under normoxic conditions. Male and female wild type (WT) and BMPR2 +/R899X mice were genotyped using amplification refractory mutation system PCR (ARMS‐PCR) with 428 bp indicating the full‐length BMPR2 and 193 bp, amplification of the BMPR2 mutated fragment. Genotyped animals were kept under normoxia for 1 month, and then perfused lung tissue was obtained to evaluate the expression level of BMPRII short and long fragment (SF/LF), phosphorylated‐SMAD1/5/8 (P‐SMAD1/5/8), β‐actin, and caveolin‐1 (Cav‐1) (a, b) by western blot or fixed for histological analysis of the microvessel area and collagen deposition using Picrosirius FAST Red staining (c, d). The percentage of fully muscularized microvessels was quantified using von Willebrand Factor (vWF; Red) and alpha‐smooth muscle actin (α‐SMA; green) staining (b, d). Normally distributed data were evaluated using the Student t ‐test. * p < 0.05, ** p < 0.01, **** p < 0.001, ns, non significant.
