Any of the cells resulting from the cleavage of a fertilized ovum during early embryonic development.
Derived from a single fertilized ovum or embryonic cell mass. Used especially of identical twins.
twins developed from the same fertilized ovum (having the same genetic material).
Of or relating to a twin or twins developed from the same fertilized ovum and having the same genetic makeup and closely similar appearance;monozygotic.
An early embryonic form produced by cleavage of a fertilized ovum and consisting of a spherical layer of cells surrounding a fluid-filled cavity.
However, the method of obtaining embryonic stem cells has created controversy in and outside Australia, because the process must destroy a fertilized ovum that may grow and become a human being.
When the cell starts to split you take out the cell and replace it into another unfertilized ovum.
