Using intracellular injection of small fluorescent molecules, we examined the gap-junctional communication properties of cells in the wing imaginal disk of Drosophila. We observed extensive spread of the injected dye between cells in all parts of the wing disk epithelium, but we found that this spread is not uniform. Instead, the cell-to-cell movement of dye is partially restricted at several defined boundaries such that cells on one side of the boundary have a low level of communication with… CONTINUE READING
