title: Guidepost cells.
abstract: Guidepost cells, as classically defined in the grasshopper embryo have only rarely been found in other systems. If the concept of guidepost cells is expanded, recognizing that any special role of specific cells in axon guidance is a function of the entire landscape in which axons are growing, and that growth cone--guidepost interactions may share mechanisms with many other cell--cell interactions, then numerous examples are found in both the peripheral and central nervous systems of many species.
