Embryos’ Signaling Proteins Go With the Flow

March 04, 2019

How cells in developing embryos communicate depend a great deal on context, according to scientists at Rice University. They found that a protein signaling pathway is known as WNT and its interactions are far more dynamic than once thought as the response of different cell types to the same signals is dramatically different. Researchers already knew that WNT, which carries messages across the cell membrane, is central to the early development of organisms and later helps stabilize cells in adults. Now they're gaining a more complete picture of the pathway's function.
