ABSTRACT
Neurogenic locus notch homolog protein (Notch) signaling mediates intracellular communication and may regulate cell fate decisions, including cell proliferation, differentiation, and apoptosis. Mesenchymal stem cells (MSCs) possess immunomodulatory properties and the potential for use in stem cell replacement treatments. The aim of the present study was to evaluate the therapeutic effects of human placentadeviated MSCs (hPMSCs) in asthma and to investigate the mechanisms of Notch signaling mediated by transplanted MSCs. A SpragueDawley rat ovalbumin (OVA)sensitized acute asthma model was established and challenged. MSCs derived from human placenta (hPMSCs) were transplanted into the asthmatic rats. Transplantation resulted in reduced Notch1, Notch2 and jagged1, and increased Notch3, Notch4 and deltalike ligand (delta)4 expression in lung, blood, and lymph samples. Notch1, Notch2, and jagged1 expression in OVAtreated rats was significantly decreased compared with controls and hPMSCtreated rats; however, Notch3, Notch4 and delta4 expression was significantly increased. Serum interferonγ significantly increased after hPMSCs transplantation, whereas interleukin4 and immunoglobulin E decreased. In OVAtreated rats, Notch1, Notch2 and jagged1 levels were increased in the lymph compared with the blood, although Notch4 and delta4 levels were decreased. Peribronchial infiltration of cells and goblet cell hyperplasia were markedly decreased in the OVA + hPMSCs group compared with those in the OVAtreated and control groups. Alterations in Notch signaling pathway expression were accompanied by decreased inflammatory cell infiltration, goblet cell hyperplasia and mucus production in lung tissues. The results of the present study are consistent with hPMSC suppression of asthma symptoms and inflammation by regulating the Notch signaling pathway in the rat asthma model.
