Each of the three major strategies of cell specification summarized in TABLE  offers a different way of providing each embryonic cell with a set of determinants (often transcription factors) that will activate specific genes and cause the cell to differentiate into a particular cell type:

Given are certain facts which define ‘specification’ of a developing embryo.

 A. At the specification stage, commitment to cell identity is labile.

 B. At the specification stage, cell is capable of differentiating autonomously.

 C. The cell “knows” very early what it is to become without interacting with other cells.

 D. A phase where inductive signals trigger cell to determines their fate.
