GFP-tagged keratin BAC reporters expressed in periderm cells at 48hpf. The first row shows maximum intensity projections, the second and third rows show optical sections highlighting the microridge-like pattern at the apical surface of cells (red outlines) or the filamentous pattern within the same cells (blue outlines). Dashed lines indicate the outlines of individual periderm cells. Images were inverted so that high-intensity fluorescence appears black and low-intensity fluorescence is white. Video 1 shows all optical sections for these images. Scale bar: 10 µm.
