Antibody | An antibody is formed to bind to a particular gene product. |
Label | The antibody is labeled so it is easily visible when bound to its antigen. |
2-8 Cells | Until the 2-8 cell stage, gene expression is consistent in all cells. |
Later | After the 2-8 cell stage, gene expression begins to vary from cell to cell. |
Conclusion | Loss of totipotency is due to differential gene expression. All cells remain genomically equivalent, though different genes become activated in different cells. |
