Decidua. (A) Necromys in mid gestation (MZUSP/APC 1140). HE. Maternal spiral arteries (MA) in the decidua (D) on their way to the junctional zone (JZ). They were associated with large cells (arrows). (B) Necromys, near term (MAV/CEMAS 01). Immunohistochemistry for vimentin. An artery in the mesometrium possessed an intact endothelium (arrow). (C) Oligoryzomys, near term (MZUSP 32729-1). Immunohistochemistry for vimentin identified remnants of the endothelium (arrow) of a maternal artery.
