Inner Cell Mass Blastomeres?

The physical and functional separation of the inner cell mass from the trophectoderm

trophectoderm
83029. Anatomical terminology. Trophoblasts (from Greek 'trephein': to feed; and 'blastos': germinator) are cells that form the outer layer of a blastocyst. They are present four days post-fertilization in humans. They provide nutrients to the embryo and develop into a large part of the placenta.
› wiki › Trophoblast
(TE) is a special feature of mammalian development and is the first cell lineage specification in these embryos. ... Each cell of the morula, called a blastomere, increases surface contact with its neighbors in a process called compaction.

Is inner cell mass pluripotent?

The inner cell mass (ICM) forms within the blastocyst, prior to its implantation within the uterus. ... The ICM is the only pluripotent cell lineage in the blastocyst. The ICM forms the epiblast and hypoblast layers, which develop into to the embryonic tissues and extraembryonic tissues, respectively.

What does the inner cell mass become?

The inner cell mass differentiates into a bilaminar embryo, consisting of an epiblast (presumptive embryonic ectoderm, mesoderm, and endoderm, as well as some extraembryonic ectoderm and mesoderm) and a hypoblast (presumptive yolk sac endoderm and extraembryonic mesoderm).
