How Cells Communicate To Activate The Cell Division Machinery

A study performed on the fruit fly unveils how distinct signaling pathways operate between neighboring cells in order to activate the cell proliferation machinery that results in the organized growth of the fly wing. The signaling pathways involved in this process are also conserved in humans, and when altered give rise to the appearance of different types of cancer, including cancer of the colon and skin, and leukemia.
