morula
Pre-blastocyst cell ball
A morula is an early stage of embryonic development, when a fertilized egg has divided into a solid ball of cells resembling a mulberry.
The morula forms before the cells hollow out to become a blastocyst.
The term appears in biology and fertility medicine: The embryo reached the morula stage on day four.
