OCR-2 reporter expression was found in sensory neurons. These sensory neurons have no known role in egg laying. In addition, OCR-2 reporter was expressed in cells of the egg-laying system. These were the four uterus-associated
uv1 cells attached to the ventral surface of the uterus, as well as the syncytial
uv1-associated cell utse. In adults, OCR-2 reporter expression was much stronger in
uv1 than in utse; in larval animals, it was the reverse.
