Introduction

Placental villi with RBC detail.

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

Placental villi Hofbauer cells^[1]

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] The cells have subsequently been named Hofbauer cells, see also the historic 1918 paper by Meyer.^[3]

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
