FIG. 6.
Expression of dys during tracheal development. Images reveal the relative dynamics of Dys and Trh protein localization and esg expression. Embryos that express lacZ in an esg pattern (esg05730 P[esg-lacZ]/TM3) were triple stained with α-β-Gal (blue), α-Dys (red), and α-Trh (green). Shown are five successive stages of dorsal trunk (DT) development and five successive stages of lateral trunk (LT) development. The stages and tracheal branch type are indicated to the left of the images. The merge column shows triple staining, and the two α-Trh column are different magnifications of the same cells. Arrowheads indicate the location of selected tracheal fusion cells.
