Fig. 2From: Expression of IL-23 in gilt endometrium and oviduct after insemination with seminal plasma, spermatozoa or semen extenderIL-23 immunolabelling in gilt endometrium at 35–40 h after insemination. Longitudinal sections of surface epithelium and sub-epithelial connective tissue of gilt endometrium (A–C). IL-23 immunolabelling in gilt endometrium after insemination with seminal plasma (A) or Beltsville thawing solution (BTS; B). C Negative control (rabbit IgG) shows no obvious staining of the endometrium 35–40 h after insemination with BTS. Representative pictures from each group are presented.
