查询词典 nymphae

In order to understand these differences on gene transcript level, even to get the genes and their expression related to cell culture, we researched the differences of total mRNA of these tissues by RAPD-PCR, the result showed that the difference between embryo and head of nymphae was much closer than embyo with others, which was accorded to the time order of insect upgrown, and the tissue which is more different from embryo on transcript level ismore diiBcult to be cultured in vitro.

四种组织的培养难易程度和分离出的细胞形态的不同，说明存在着组织表达的差异，为了从转录水平上来认识它们的差异，甚而获得与细胞培养难易相关的基因及其表达产物，本实验还采用了RAPD分析的方法进行了这四种组织：中后期虫卵胚胎、若虫头部组织、成虫的精巢和卵巢的mRNA表达差异研究，结果表明：从发育方向上看，四种组织的表达差异有分化越大差异系数越大的趋势，而在相同条件下则越难培养。
