A personal message from Dr Mark Hill (May 2020)  
Mark Hill.jpg
I have decided to take early retirement in September 2020. During the many years online I have received wonderful feedback from many readers, researchers and students interested in human embryology. I especially thank my research collaborators and contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!

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
