Effects of normal and PE sera on CRL1730 cell apoptosis. Apoptosis was determined in CRL1730 cells treated with serum from normal and PE pregnant women using Annexin V and PI double staining methods. A) 24-h normal pregnant group; B) 48-h normal pregnant group; C) 72-h normal pregnant group; D) 24-h PE group; E) 48-h PE group; and F) 72-h PE group. A representative image from three independent experiments is shown.
