查询词典 somatic effect

Although the biological significance of DNA methylation has been recognized to some extent, the mechanisms of DNA methylation regulation and of the establishment of tissue-specific DNA methylation pattern in somatic cells are still unclear, since the knowledge of the enzymes responsible for de novo DNA methylation and demethylation of DNA is very limited and up to now only two functional DNA methyltransferases in mammals have been cloned.

目前，虽然对DNA甲基化的作用已有一定认识，但DNA甲基化的调节以及发育过程中组织特异的DNA甲基化谱的建立机制还不清楚。问题主要在于对催化重新甲基化和去甲基化反应的酶的了解很少。至今仅克隆出两种有功能的哺乳动物DNA甲基转移酶。

During somatic embryogenesis, we were able to trace the FAC1 expression to single embryogenic cells, suggesting its critical role in early induction.

FACl在体细胞胚胎发育过程中的表达可以追踪到单个的胚性细胞，说明它在激活早期胚胎发育中的关键地位。

We propose that, in inducing pluripotency, the number of reprogramming factors can be reduced when using somatic cells that endogenously express appropriate levels of complementing factors.

之所以有可能这样，是因为这些神经细胞比胚胎干细胞表达更高水平的内生Sox2 和 c-Myc，这说明具有适当匹配的转录因子的体细胞是生成iPS细胞的一个潜在有用的起始点。

The results showed that karyotypic type of Ya01-21was 2n=104＝100m+4sm（4SAT）, Chromosome length ratio of the longest and the shortest 4.25, the average arm-ratio 1.35, belonging to 2C type of chromosome. Molecule identified combine with chromosome studied indicated that Ya01-21 was a progenies of Erianthus arundinaceum. following the law of n+n; ITS identify showed that Ya01-21 is a progenies of Erianthus arundinaceum, the somatic chromosome karyotypic type of Ya01-36 was 2n=132＝130m+2sm, Chromosome length ratio of the longest and the shortest 3.94, the average arm-ratio 1.27, belonging to 2B type of chromosome, combining the advance of characters the law of 2n+n can be resumed.

研究结果表明，崖城01－21的体细胞染色体核型公式为2n＝104＝100m+4sm（4SAT），最长与最短染色体的长度比为4.25，平均臂比1.35，染色体属2C型，分子鉴定结合细胞学研究认为其为斑茅的真实后代，其染色体遗传为n+n；崖城01－36经ITS签定为真实杂种，其体细胞染色体核型公式为2n＝132＝130m+2sm，最长与最短染色体的长度比为3.94，平均臂比1.27，染色体属2B型，结合其性状的进展，推断亲本向其传递染色体可能以2n+n的方式进行。
