trofoblasti
Trofoblasti are the cells that form the outer layer of the mammalian blastocyst and participate in implantation and placental development. They are derived from the trophectoderm, the first lineage to differentiate from the inner cell mass after fertilization.
During placentation, trofoblasti differentiate into two main lineages: cytotrofoblasts, which proliferate to form a continuous monolayer,
Functions of trofoblasti include mediating nutrient and gas exchange between mother and fetus, producing hormones such
Clinical relevance is significant: impaired trofoblast invasion or function is associated with obstetric complications such as
