Epiblast Ca2+ waves propagate from the apical to basal domain. The images show selected time points from movies of E5.5 GCaMP6f embryos imaged using a ZEISS lattice light-sheet 7 microscope. Top row: An example of an epiblast wave involving a large proportion of the tissue captured by imaging a volume of the embryo at 20-s intervals. A total of 9/16 embryos showed at least one epiblast Ca2+ wave. Bottom row: Faster imaging at 5-s interval revealed that the Ca2+ wave in the epiblast can be preceded by a transient in a neighboring VE cell—this was observed in 5/19 events from 9 embryos (white arrowheads).
