ANGPT1 and pulmonary edema: In endotoxin-induced lung injury, the protective effects induced by MSC-EVs on pulmonary edema were mediated partly by transfer of KGF mRNA to airway epithelial cells and angiopoietin-1 (Ang-1) mRNA to endothelial cells (Zhu et al., 2014; Tang et al., 2017; Mahida et al., 2020b).
