Serous ovarian cyst fluids contain high levels of endometrial placental protein 14.

Abstract

This paper reports the detection and characterization of endometrial placental protein 14 (PP14) in human ovarian cyst fluids. PP14 from ovarian cyst fluid has the same molecular size as PP14 purified from human amniotic fluid. No clear difference was found in the PP14 concentrations between benign, borderline and malignant cyst fluids, but serous ovarian cyst fluids had significantly higher PP14 concentrations (median 253.3 micrograms/l) than mucinous cyst fluids (median 17.5 micrograms/l).
