Fig. 7. Loss of Par-1 disrupts Delta localization during lateral inhibition. Embryos were injected with buffer (A,E) or par-1 dsRNA (B-D,F-H) and immunostained at stage 9 for Notch (A-D) or Delta (E-H). All embryos were stained for E-cadherin. (A,B) Merged image of Notch (green) and E-cadherin (red), with individual channels in B shown in (C-D). (E,F) Merged image of Delta (green) and E-cadherin (red), with individual channels in F shown in (G-H).
