inner cell mass

The cluster of cells located inside the blastocyst that eventually develops into the embryo proper.

Noun

pl: inner cell masses

This term is a specialized biological designation used primarily in embryology and developmental biology. It describes a specific group of pluripotent cells that possess the capacity to give rise to all the tissues of the body, distinguishing them from the surrounding trophoblast cells which form the placenta.

In a clinical or laboratory context, the inner cell mass is the source of embryonic stem cells. Because it refers to a specific anatomical structure within a blastocyst, it is treated as a singular entity in most scientific descriptions.
