7.3 ​POJA-L1442. Survey of the chorionic plate and intervillous space (human placenta, full-term)
7.3 POJA-L1442
Title: Survey of the chorionic plate and intervillous space (human placenta, full-term)
Description: Stain: Perjodic acid-Schiff reaction (PAS). At the top the chorionic plate (1) with cross-sections of umbilical vessels (2). At (3) the folded amnion covering the chorionic plate. Ramifications of thicker stem villi demonstrate free-floating terminal villi (tertiary). At several places reddish-stained PAS-positive fibrinoid accumulations (4) associated with the villi are present. On the opposite side (bottom) the maternal decidua is stripped off, but the decidua cells still appear PAS positive (arrows 5).
Keywords/Mesh: placenta, tertiary villi, decidua, chorionic plate, chorionic villi, trophoblast, histology, POJA collection.
