 Induction of ectopic tracheal fates by the Trh–bSim construct. (A) Wild-type 1-eve-1 embryo shows staining of the trh enhancer trap in the 10 tracheal pits. (B,C) Ectopic expression of the Trh–bSim construct induced the formation of ectopic pits (tp0 and tp11), as monitored by the expression of the btl H82 enhancer trap. (D) The Trh–bSim construct also induced the expression of tracheal lumen antigens on the ectoderm at stage 15 (arrowheads), as monitored by anti-lumen antibodies (no. 84).
