| description | A trophoblast cell that invades the uterine wall to anchor the placenta to the uterus. An interstitial extravillous trophoblast cell differentiates from an extravillous trophoblast cell, becoming hyperchromatic and changing its morphology to a fibroblast-like spindle-shaped cell. In humans, this cell can be distinguished by the expression of placental-specific protein 8, which stimulates migration. |
