Answer:
1) Cells exhibit a characteristic called "contact inhibition." Cells will grow and divide until they begin to touch other cells. Then cells will slow down their division and will eventually stop reproducing.
2) Cells have chemical signals that tell them when to divide more rapidly, and cells that are nearby send signals for other cells to slow down or stop dividing. These signals ensure that cells don't "overgrow" their boundaries and get in the way of other tissues. On the other hand, if you were to cut your finger, the cells around the wound would receive signals to divide more quickly so that the cut could heal.
