Human Term Placental Villi
- Placental villi at term.
- Note both the larger number of smaller villi at the same magnification as the first trimester.
- The second difference is in the cell layer now forming the shell of each villi.
- 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.
