Details of the outer girdle field and the plate fields. ac Tube-likes structure of the presumptive spicule formation cells (arrows) in the outer girdle field (ogf). a CLSM 3D projection showing F-actin “tubes” (arrows). b, c Semithin section cross the outer girdle field showing similar structures (arrows). c is a magnified image corresponding to the area indicated by the box in b, in which the two recognizable tubes are highlighted by dashed lines. d Longitude section showing the posttrochal region of a 48-hpf larvae, with anterior to the right and dorsal on the top. Plate fields (arrowheads) and ridges (arrows) can be recognized. Note that the cells adjacent to the prototroch (pt) are not invaginated, indicating that the first plate field does not reach this distance. Bars represent 20 μm
