Extended Data Fig. 8. Other patterns of ER dynamics in saltatory moving cells.
a–b, Time-lapse sequences of a SEC61B-mEGFP+ cell in hSO (a) or hCO (b) moving in a saltatory pattern. The hFA is generated by assembly of SEC61B-mEGFP hSO with unlabeled hCO. Triangles mark the nucleus and arrows mark ER localization at the leading branch or the trailing process during saltatory movement. The cell in (a) showed no detectable ER displacement. The cell in (b) has partial ER signal “left behind” the nucleus after nuclear translocation.
