Verified step by step guidance

Understand the role of the trophoblast in early human development. The trophoblast is the outer layer of cells in the blastocyst, which is an early stage in the development of the embryo.

Recognize that the trophoblast is responsible for facilitating implantation into the uterine wall. This is a key function as it helps the blastocyst attach to the uterine lining.

Acknowledge that the trophoblast contributes to the formation of the placenta. The placenta is crucial for nutrient and gas exchange between the mother and the developing embryo.

Identify the inner cell mass as a separate component of the blastocyst. The inner cell mass is responsible for forming the embryo itself, not the trophoblast.

Conclude that the statement 'It differentiates into the inner cell mass' is NOT a property of the trophoblast, as the inner cell mass is a distinct part of the blastocyst that does not originate from the trophoblast.
