Co-expression analysis of marker genes by double fluorescent WMISH during the development of Ph. harmeri. Relative spatial expression of otx and foxA (a), otx and gsc (b, f, l), gata4/5/6 and foxA (c), foxA and twist (d), six3/6 and twist (e, h), cdx and nk2.1 (g), bra and nk2.1 (i), bra and foxA (j) and six3/6 and otx (k). Right insets in d, e, k show embryos in vegetal view. Every picture is a full projection of merged confocal stacks. Nuclei are stained blue with DAPI. Anterior is to the left
