We tested the speculation that phenotypically modulated steady muscles cells (SMCs) and related irritation are associated with the development of experimental occlusive pulmonary vascular disease (PVD). Plexiform lesions composed SMA+, vimentin+, SM1-, SM2- myofibroblasts protected by endothelial monolayers. Immature SMC-rich plexiform and intimal lesions had been proliferative and had been infiltrated by macrophages, while fibrous… Continue reading We tested the speculation that phenotypically modulated steady muscles cells (SMCs)
