Fig 1: rhIL-37 inhibited the development of lesion in the endometriosis mouse model. At 24 h after the last rhIL-37 administration, (A) the formation of ectopic lesions were observed; (B-C) the weight and volume of ectopic lesions were measured; (D-H) the serum IL-37, IFN-γ, TNF-α, IL-4, and IL-13 levels were measured using ELISA assay. N = 6. **P < 0.01 compared with Control, and ##P < 0.01 compared with EMs
