Mitogens match cell numbers to local demand.
Although the control of cell proliferation has been studied intensively at the level of the single cell, less is known about how cell numbers are controlled in developing populations and organs. Often, proliferation provides a pool of cells for organ construction, but the rate of this proliferation must be coordinated with patterning to avoid imbalances in cell numbers. Recent research on the development of the Drosophila eye and the proliferation signals (mitogens) can act to coordinate cell numbers.
