Patterning of the autocentrum. Confocal images of the osteoblast transgenic reporter sp7:nlsGFP, counterstained with the bone marker alizarin red S, were taken at different stages of zebrafish development to show the conformation of the compound centrum. Terminology: aut, autocentrum; cU1 + 2, ural chordacentrum 1 + 2; H1–5, hypurals 1 to 5; haPU1, haemal arch of the preural centrum 1; naPU1-U1-U2, neural arch of the preural centrum 1 or ural centra 1 or 2; PL, pleurostyle. Scale bar: 100 μm
