Cells in an embryo’s _______________ will later form muscle, bones, and the circulatory system.

select one or more statement correctly describe how inner cells can be distinguished from outer cells in the pre-implantation mouse embryo Outer cells are sealed via zippering of actin rings, inner cells are not sealed. Hippo signalling is off in the outer cells, but on in the inner cells.Outer cells are pluripotent (= giving rise to any organ of the adult body), inner cells are determined to give rise to extraembryonic tissue only Inner cells have a “contact-free” surface, outside cells are entirely surrounded by neighbour cells.
