Impaired endothelial layers in severe preeclampsia
The results are shown in Figure 2. Endothelial cells in the NP group were uniformly and regularly arranged, and the nucleus was oblong, bluish and protruded slightly from the official cavity (Fig. 2A). In the SP group, the walls of placental arterioles were thickened, collagen fibers were increased, the arterioles were hyalinized, the endothelial cells were disorderly arranged, and the endodermis was obviously damaged (Fig. 2B).
