Iterative Relay of EGFR-ERK Signaling Regulates Epithelial Invagination via a Wave of Cellular Contractility

Activity of ERK FRET biosensor was was quantified from time-lapse images of Drosophila embryos carrying pubi-ekarev-nes and pubi-TagRFP-T-CAAX. TagRFP-T-CAAX signal was used to segment cells and averaged FRET/CFP ratio and position (in polar coordinate) or time of each segmented cell is listed in each table. Those data set were used to create the graphs in Figure 1 of Ogura et. al.(2018).
