| pubmed-article:12387199 | pubmed:abstractText | Successful implantation and placentation are essential for the normal intrauterine development of the fetus. Trophoblast cell proliferation, differentiation, invasive behaviour and interaction with the maternal immune system are known to have an impact on these processes. Trophoblast cells do not only physically anchor the developing fetus to the uterus, but they give rise to the syncytiotrophoblast. This is the principal endocrine component of the placenta, and participates in essential metabolic processes and in the defence against transplacentally transmitted infections. Therefore, placental trophoblasts play an important role in the establishment and maintenance of pregnancy. | lld:pubmed |
