Question

What does cell size in a proliferating cell population require?

Answer 1

Cell proliferation:

1. It is the process of increasing the number of cells.
2. It is characterized by the equilibrium between dividing cells and cell loss via cell death or differentiation.
3. In a growing cell population, cell size must be maintained by doubling in mass during each cell cycle.
4. To coordinate growth and division, the signaling pathways that govern cell growth are often related to those that control cell division in some way.
5. In yeast, for example, the rate of cell division is proportional to the rate of cell growth, thus cells divide only when a certain growth rate is reached.
