Abstract
A gradient of EGFR-ERK signaling has been classically implicated in various developmental processes. In this issue of Developmental Cell, Ogura et al. (2018) show that in the Drosophila tracheal placode, EGFR-ERK signaling propagates via a cell-by-cell relay mechanism rather than a gradient, and this sequential ERK activation controls proper placode invagination.
