| When Fisher and researchers at a fertility clinic examined unused human embryos donated for research, they found that human trophoblasts make L-selectin. |
| Flt-1 is also present on trophoblasts and macrophages, whereas KDR is present on hemopoietic stem cells, megakaryocytes, and retinal cells. |
| Membrane microscopic chorionic pseudocysts are associated with increased amount of placental extravillous trophoblasts. |
| Placental trophoblasts express and produce coagulation components, participating not only in haemostasis but also in placental vascular development and differentiation. |
| Choriocarcinoma is a malignant tumor derived from trophoblasts that has high metastatic potential. |
| The placenta derives from embryonic cells called trophoblasts, which form a ball around the cells that ultimately develop into the fetus. |
