This structure forms in the earliest steps of development, before implantation into the endometrium of the uterus has occurred.The ICM lies within the blastocyst cavity and is entirely surrounded by the single layer of cells called trophoblast. [Wikipedia:Inner_cell_mass]
A group of cells found in the mammalian blastocyst that give rise to the embryo. [Biology_Online][VHOG]
