Trophoblasts are the outermost cell layer of a blastocyst primarily responsible for the implantation process [1]. A trophoblast develops into extra-embryonic tissues, and these include the placenta. [2]
Trophoblasts are specialized cells that play a pivotal role in the early stages of mammalian development, particularly in the formation of the placenta. Originating from the outer layer of the blastocyst—the early stage embryo—trophoblast cells have the primary functions of facilitating embryo implantation and interfacing with the maternal endometrium to establish nutrient and waste exchange.
Trophoblasts also functions in controlling oxygen and metabolite exchange that transpires between the embryo and the mother [3]. Trophoblasts are also sometimes referred to as trophoderm. [4]
During early pregnancy, the trophoblast cells undergo differentiation and invasion, which are essential for placenta formation and successful pregnancy outcome. Differentiation includes the transformation from cytotrophoblasts to syncytiotrophoblasts and extravillous trophoblasts, as mentioned above.
