Exosomal miR-221-3p derived from bone marrow mesenchymal stem cells alleviates asthma progression by targeting FGF2 and inhibiting the ERK1/2 signaling pathway
Abstract:Exosomes derived from human bone marrow mesenchymal stem cells (BMSCs) play potential protective roles in asthma. However, the underlying mechanisms remain not fully elucidated. Herein, exosomes were isolated from BMSCs, and their morphology, particle size and exosome marker proteins were identified by transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA) and Western blot, respectively. Then airway smooth muscle cells (ASMCs) were treated with transforming growth factor-β1 (TGF-β1) to… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
