CXCL14 and endometritis: To investigate whether CXCL14 mediates the protective effect of guanosine in ameliorating E. coli‐induced mouse endometritis, we employed an anti‐CXCL14 monoclonal antibody which is capable of neutralizing CXCL14 in vivo to assess the impact of CXCL14 on the protective effect of guanosine in improving E. coli‐induced endometritis (Figure8A).
