查询词典 reprogramming

During the two critical periods—gametogenesis and preimplantation development, there are genome-wide epigenetic reprogramming in gametes and embryos, which plays important roles in the erasion or creation of imprinting, gene silencing and tissue-specific gene expression.

其中关键时期是配子形成期和胚胎植入前期，最主要内容是全基因组DNA"CpG岛"甲基化和染色质组蛋白乙酰化的有规律变化，结果是配子遗传印记的消除与重建、植入前胚胎大范围基因的静默和组织特异性基因表达的确定。

It was shown that glia cells need some days for the reprogramming until they take the normal shape of a nerve cell.

结果表明，胶质细胞在呈现一般的神经细胞形状之前，需要几天的程序调整时间。

But this is the litmus test for finding the genes that are essential for reprogramming, he says.

他说"但这种试验是至关重要的"，因为人们发现了基因对细胞的改编过程是必不可少的。

We're setting the foundation for reprogramming healthy life, said Valter Longo, the study leader.

研究负责人瓦尔特·朗哥表示："我们正在为健康生命的程序重设奠定基础。"

In any case, scientists would have to deliver different reprogramming signals to other kinds of cells, Melton said.

Melton说，科学家将不得不把不同的重组信号传送到其他细胞。

Recently generated ESC-like pluripotent cells by reprogramming somatic cells, named induced pluripotent stem cells, open a new gate for cell transplantation-based regenerative medicine.

经体细胞重编程产生的诱导多能干细胞(induced pluripotent stem cells， iPS)也被证明有类似胚胎干细胞的特性。

These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

以上结果显示，6－DMAP能增加胚胎干细胞异种重构卵的卵裂率，对重构卵囊胚的发育率影响不大；高培养代数和低培养代数的胚胎干细胞用于异种核移植不影响异种重构卵的卵裂率和囊胚发育率；用胚胎干细胞作为供核细胞；比体细胞作为供核细胞所构建的异种重构胚更容易进行重编程，并且胚胎于细胞指导异种克隆胚胎正常发育的能力强于体细胞。

Such direct reprogramming, however, might be simpler and safer than using pluripotent cells to treat some diseases.

但是，这种直接编程在治疗疾病方面，可能比运用多细胞疗法更简单和更安全。

Reprogramming a program memory is done through a serial cable in a program for application development.

在应用程序开发中，通过一个串行电缆可以对程序存储器进行重新编程。

The cloning of mammals by somatic cell nuclear transfer requires epigenetic reprogramming of the differentiated state of donor cell to a totipotent, embryonic ground state.

由于供体核支持整个克隆动物的发育，所以当供体核被移入去核的卵母细胞后，必需进行重编程，回到胚胎发育的起始阶段。

Aquatic or marsh-growing fern allies; known to have existed since the Cenozoic; sometimes included in Lycopodiales.

生活于水中或湿地的蕨类；从新生代生存至今；有时归于石松目之中。

The engine was uprated from a 90hp Franklin to a 125hp Lycoming.

改良过的引擎是从90hp到125hp莱康明富兰克林。
