Abstract：Using whole mount and tissue section in situ hybridization techniques , the expression patterns of two Sox9 homologues genes ,Sox9a and Sox9b,were comprehensively compared and analyzed in four stages of developing embryo (12, 24, 48 hpf and 4 dpf) and mature gonads of zebrafish (Danio rerio).The two genes were persistently expressed in brain and eyes ,but differentially expressed in otic vesicle , head cartilage , pectoral fin buds and somites .Distinct from high expression of Sox9b in the yolk granules of oocytes, Sox9a was specifically expressed in lateral line , tail neural crest , primary renal tubular and Sertoli cells in testis . Compared with other published results , the present data revealed a more extensive differential expression pro-file of two Sox9 genes in the developing embryo and gonads of zebrafish .
