Expression pattern of polycomb gene Nspc1 at the early developmental stage in zebrafish / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To study the expression pattern of Polycomb gene Nspc1 at the early developmental stage in zebrafish.</p><p><b>METHODS</b>In situ hybridization probe for Nspc1 was designed according to the GenBank information. Collecting zebrafish embryos at different stages including one cell stage, two-cell stage, bud stage, and somites stage, we hybridized them with the prepared probe. Then the hybridization signals at different intervals were observed and photographed at the right time.</p><p><b>RESULTS</b>Nspc1 was expressed globally at the early stage. Its expression specificity began at the somites stage, mainly in the nervous system of the head.</p><p><b>CONCLUSION</b>Nspc1 may play essential roles in the early stage development of zebrafish, especially in the nervous system.</p>
