In the development of the embryonic stage, the morula staged group of cells (blastomeres) change into blastocyst. The cells within this form an outer layer called trophoblast - attaches to the endometrium of uterus. The inner cells of the structure form the inner cell mass which later differentiates into embryo proper.
