![](images/spacer.gif) Schematic diagrams of the Drosophila embryo at different developmental stages (left panel) and the wild type host embryo for microinjection of dsRNAs stained with X-gal, showing the expression pattern of the D-mef2-lacZ reporter gene and normal heart morphology during embryogenesis. S12, S13, and S17 indicate the different embryonic stages 12, 13 and 17, respectively. CC, SC and DV designate cardial precursor cells, a subset of somatic muscle founder cells and dorsal vessel (heart), respectively. |
