It is in just those few cells in the inner cell mass that we have our origins.

This removes the constraint on the physical size of the cell mass.

The hypoblast is a tissue type that forms from the inner cell mass.

The inner cell mass can be used for stem cell research.

This is because the inner cell mass has not been affected by external factors.

The epiblast layer is derived from the inner cell mass.

This will lead to one inner cell mass and one blastocyst.

The internal organs are lost in varying degrees down to a cell mass.

It is responsible for moving cells toward the inner cell mass in developing blastocysts.

He extended this work to study physical properties of mammalian cell mass and stiffness.
