Human Term Placental Villi

  • Placental villi at term.
  • Surface layer of vill now lack cytotrophoblast cell layer and now are covered with only a syncitotrophoblast layer (shell).
  • Syncitotrophoblast layer is variable in thickness from a thin cytoplasmic layer to regions of clumped nuclei.
  • Vill core mainly occupied by fetal capillaries and larger blood vessels, with only a small amount of connective tissue.
  • Fetal red blood cells now appear to lack the earlier distinctive nuclei.
