Architecture of Normal Villous Trees

  • Chapter
Pathology of the Human Placenta

Abstract

The ramifications of the villous trees can be subdivided into segments that differ mainly as to caliber, stromal structure, vessel structure, and position within the villous tree (Figure 7.1). Five villous types have been described (Kaufmann et al., 1979; Sen et al., 1979; Castellucci & Kaufmann, 1982a,b; Kaufmann, 1982; Castellucci et al., 1984, 1990; Burton, 1987), some of which can be further subdivided. As is discussed, all villous types derive from single precursors, the mesenchymal villi, which correspond to the tertiary villi of the early stages of placentation.
