Effects of the intrauterine device (IUD) on transcripts of prostaglandin-endoperoxide synthase-2 (PTGS2) (A, D), prostaglandin E2 synthases (PTGES) (B, E) and prostaglandin F2α synthases (PTGFS) (C, F) in equine epithelial (A, B, C) and stromal (D, E, F) cells, collected during the early luteal phase, after 24 h of incubation with the presence of IUD. Succinate dehydrogenase A (Sdha) – reference gene. Asterisks indicate significant differences (*P < 0.05; **P < 0.01; ***P < 0.001) from the respective control
