Next, we established a murine peritoneal endometriosis model to confirm this finding (Figure 1B), and ELISA results showed that chemerin was significantly enhanced in peritoneal lavage fluids of EM mice (3131.6 ± 102.7 pg/ml) compared with those of sham-treated mice (2814.9 ± 120.2 pg/ml) (Figure 1C). Here, RARRES2 is linked to erythema multiforme.
