Certain cells inhibit cell division by expressing signaling molecules on their surfaces. These molecules are MOST likely involved in which of these processes? Anchorage dependence, apoptosis, density-dependent inhibition, or transformation?
The molecules expressed on the surfaces of the cells that inhibit cell division are MOST likely involved in density-dependent inhibition. In density-dependent inhibition, when cells are crowded together and the cell density reaches a certain threshold, these molecules send signals to neighboring cells to stop dividing, thereby preventing excessive cell growth and maintaining tissue homeostasis.
