Blastocyst: Implantation is initiated

Implantation is initiated, when the blastocyst comes into contact with the uterine wall. The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass, which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoele. The trophoblast gives rise to the placenta. In humans, blastocyst formation ... The blastocyst is composed of the outer cell layer called as the trophoblast and the inner cell mass. The inner cell mass will form all the tissues of the embryo and differentiate into embryo proper. The trophoblast will form the placental structures. När plussade ni med blastocyst ? Vilket test? Jag är på ruvardag fem med en blastocyst . Testade i dag men inte en tillstymmelse till extra streck. Testade med test från Testlagret och de testerna ska ju vara extremt känsliga. Dessutom fäster ju blastocysten för det mesta det första dygnet efter insättning. Alltså borde det vara kört nu, eller? När har ni plussat med blastocyst och vilket test använde ni? This is followed by formation and development of blastocyst and its attachment to the uterine wall (implantation), embryonic development (gestation) and delivery of the baby (parturition).
