Construction and verification of the plasmid including IL-33. a Morphology of MSCs infected with lentivirus observed under an inverted fluorescence microscope (left panel, bright field; right panel, fluorescence field). Bar, 200 μm. Real-time PCR (b) and ELISA (c) were used to determine the expression of IL-33 in MSCs infected with different lentivirus. ***P < 0.001, as indicated, ANOVA. Each experiment was performed three times
