Live visualization of a GMR>cindr-IR2+3 retina 18–22 h APF. Selected pre-1° cells are pseudo-colored in shades of green to emphasize the displacement of one pre-1° cell by another cell (left ommatidium) and the unstable 1°–1° cell interface (right ommatidium); AJs were detected by expression of α-cateninGFP.
