Abstract Background Asthma is a chronic respiratory illness characterized by lung tissue remodeling, T helper cell imbalance, and the generation of inflammatory factors. The Human amniotic mesenchymal stem cells-conditioned medium (hAM-MSC-CM) contains various immunomodulatory components and has been utilized in certain studies as a source for anti-inflammatory factors. We investigated the impacts of CM on splenocytes pro-inflammatory cytokines and alpha-smooth muscle actin (α-SMA) expression in Balb/c mice with Ovalbumin (OVA)-induced asthma.Methods and results Forty mice were separated into four groups of ten: control (challenged and sensitized with normal saline solution), asthma (sensitized on days 1, 8, and 14 and challenged daily with OVA from days 21 to 28), OVA+CM (asthmatic mice treated with CM on days 29 and 30), and OVA+DMEM (DMEM-treated asthmatic mice on days 29 and 30). The spleen and lung tissues were removed 48 hours after the final challenge, and the expression of the inflammatory factors in the splenocyte culture supernatant was determined by ELISA, while the α-SMA expression in the lung was determined using western blotting. α-SMA protein expression was significantly greater in lung tissue. Also, inflammatory agents were significantly higher in the splenocytes supernatant in the DMEM and asthma groups compared to the control group. CM therapy has been shown to inhibit the production of the α-SMA protein and inflammatory cytokines. Conclusions Results showed that CM Treatment was able to decrease the α-SMA expression in lung and splenocytes pro-inflammatory cytokines.
