From: Myogenesis in the sea urchin embryo: the molecular fingerprint of the myoblast precursors

Figure 6

Dynamics of gene expression in the putative myoblast precursors of the sea urchin embryo. Fluorescent whole mount in situ hybridization and relative position of FoxY (green), FoxC (red) and FoxF (magenta) transcripts in the interval from 24 to 45 h. Each picture is a full projection of merged confocal stacks. Yellow circles indicated by yellow arrowheads show co-expression cells; white circles show absence of co-expression. White arrows in panel A indicate the emergence of FoxY transcription in the NSMs. For single-channel full projections of the images reported in D-I see Additional file 11: Figure S9. All the embryos are viewed in lateral view along the animal top/vegetal down axis with the exception of A, B and C that are seen in a vegetal view. Nuclei are labeled blue with 4',6-diamidino-2-phenylindole (DAPI).
