Expression of PfCdx and PfXlox in transforming larvae. Whole mount (A, D) and sagittal sections (B, E) of the transforming larvae hybridized with antisense probes against PfCdx (A-C) or PfXlox (D-F). Panels C and F are higher magnifications of panel B and E, respectively. Arrows and arrowheads indicate the in situ hybridization signals of PfCdx and PfXlox, respectively. The scale bar is 200 μm.
