Endothelial dysfunction and vascular remodeling are the hallmarks of pulmonary arterial hypertension (PAH). For PAH treatment, there is a rising demand of Stem cell therapy. Interestingly, research reveals that stem/progenitor cells may have an impact in disease progression and therapy in PAH patients. Clinical trials for stem cell therapy in cardiac cell regeneration for heart repair in PAH patients are now underway. The clinical potential of stem/progenitor cell treatment that offers to PAH patients helps in lesion formation which occurs through regaining of vascular cell activities. Majorly the stem cells which are specifically derived from bone marrow such as mesenchymal stem cells (MSCs), endothelial progenitor cells (EPCs) and induced pluripotent cells (iPSCs), adipose-derived stem cells (ADSCs), and cardiac stromal cells (CSCs) are among the subtypes that are proved to play a pivotal role in the repair of the heart. But with only MSCs and EPCs, have shown positive outcomes and act as therapeutically efficient in regaining cure for PAH in clinical trials. This chapter also seeks to explain the potential limitations and challenges with most recent achievements in stem/progenitor cell research in PAH.
