Having worked out how early embryos can be used as synchronous models for studies, then we are able to isolate cells at different cell cycle stages. Cells were isolated and fused together by addition of

. This fused cell is known as

due to the presence of 2 nuclei.

The conclusions from cell-fusion experiments were the following: 1. Mitotic cells contain an M-phase activator that will push a cell in any phase of the cycle (directly/indirectly/gradually)

into mitosis. S-phase cells contain an

that pushes G1 cells into S-phase. G2-cells were found to be (sensitive/insensitive)

to S-phase promoting factor. This is a

mechanism. G1 and G2 phases do not contain either of the factors.
