Glycogen cells in mid gestation. (A) Hylaeamys (MZUSP/APC 1022-1). PAS. Glycogen cells (arrows) at the outer margin of the junctional zone (JZ) just above the decidua (D). (B) Necromys (MZUSP/APC 1140). HE. Glycogen cells (arrows) invading the decidua near a maternal blood channel (MBC) that was entering the placenta. (C) Necromys (MZUSP/APC 1140). Immunohistochemistry for cytokeratin confirmed the trophoblastic nature of cells that originated from the junctional zone and invaded the decidua.
