ABSTRACT

Background: Asthma is affecting more than 300 million people worldwide, which represents the most common chronic disease among children. We previously found that mesenchymal stem cells (MSCs) derived from induced pluripotent stem cells (iPSCs) modulated the immune response on Th2‐mediated asthma in vivo and in vitro. This study further evaluated the immunomodulatory effects of MSCs from human embryonic stem cells (hESCs) on asthma. Methods: Multipotent hESC‐MSCs were obtained using a feeder‐free method. The hESC‐MSCs were analysed for the expression of stem cell surface markers by flow cytometry, their differentiation potentials were analysed using in vitro trilineage differentiation methods hESC‐MSCs were transplanted into the murine model with ovalbumin (OVA)‐induced airway allergic inflammation. The expression levels of allergic related genes were measured by the mRNA PCR arrays. Results: The hESC‐MSCs expressed classical MSC markers and held the capability of differentiation into multiple mesoderm‐type cell lineages. hESC‐MSCs were able to suppress allergic inflammation by modulating Th2 cells and eosinophils in the mice, and reversed the reduction of regulatory T cells. By using PCR array, 5 mRNAs‐ chemokine (C‐C motif) ligand 11 (Ccl11), Ccl24, interleukin13 (Il13), Il33 and eosinophil‐associated, ribonuclease A family, member 11 (Ear11) were identified the most relevant in murine airway allergic inflammation and hESC‐MSCs treatment. Conclusions: The therapeutic effects of hESC‐MSCs were identified in the murine model of airway allergic inflammation with key mRNAs involved. This study will provide a better understanding regarding the mechanisms underlying hESC‐MSCs therapeutic application in airway allergic inflammation.
