Diagram of sample collection procedure. (A) After slaughter, reproductive tracts were trimmed free of connective tissues; (B) The uterine horn ipsilateral to the corpus luteum was isolated. Starting from the utero-tubal junction (UTJ), locking tweezers were positioned every 8 cm to isolate the anterior, medial and posterior uterine thirds. (C) The ipsilateral anterior third was individually flushed by injecting 3 mL of PBS into the UTJ edge. (D) Intercaruncular endometrial samples were dissected from the UTJ (black arrow) and from the lengthwise intermediate region (white arrow) of the third, at the mesometrial side.
