Figure 2. The function of tinman in the formation of mesodermal tissues. The (eft column shows wild-type embryos and the right column tinman mutant embryos of the same stage and stained with the same markers. (A, B) Neither cardioblasts nor pericardial cells are formed in tin mutants (embryos stained as in Figure 1 ). (C, D) The midgut musculature (stained for flCal expression from an enhancer trap insertion is completely m ssing in tinman mutants. (E, F Dorsal muscles (stained for [iCa expression from a .cZ reporter insertion Yin and Frasch, 1998) are not properly specified in tinman mutants. (G, H) Earlv stage 12. The muscle founders of the S59 cluster I (as detected with an S59 antibody), which give rise to muscles 5 and 25, are not specified in tinman mutants. By contrast, the founder cells of S59 cluster II are formed normally and will develop into muscles 26, 2(r, and 29, (I, J) Stage 11. huttonlesi niRN.A expression in the DM cell precursors (arrow) is absent in tin mutants and DM cells are not formed.
