Fig. 4

Process of morphogenesis of the fin rays and radials. Calcified bones (Alizarin Red) and chondrogenic cells (col2a:EGFP) of the left pectoral fin in individual tracing specimens were observed at 28 dpf (a), 32 dpf (b), 36 dpf (c), and 40 dpf (d). The observed fish were crossbred. Orange arrowheads with numbers indicate the most posterior fin ray. White arrowheads with dr3–7 indicate newly appearing distal radials. The scale bar in a indicates 200 μm. CSZ, cartilage subdivision zone. sc, anlagen of the scapula. The asterisk in a indicates the reflected signal of the iridophore on the swim bladder
