Introduction
This page introduces the histology of the placenta, the placental cord and fetal membranes.
Various developmental stages of the placental villi are shown including maternal decidua.
There are images of placental cord and the placental vessels (vein and arteries).

Hofbauer Cells
Hofbauer (1903) identified a sub-population of cells in the placenta that could be identified by specific histological stains, the finding he published 2 years later in 1905.[2]
- human villous macrophages
- highly vacuolated cells
- located the core of placental villi and cord
- macrophages with micropinocytotic activity and phagocytosis ability
- possible paracrine role for early stages of placental vasculogenesis
