再分化

The reliance of regional tourism to the information is the internal agent of tourist managemental informatization,which is the base of an electric goverment.

江西的旅游信息建设经过分化整合及经营策略的再探索，取得了一定的成效，已逐渐进入一个成熟稳健的发展时期。

All of those confirmed the odontogenetic ability of adipose-derived stem cells, offered theory and experimental basis for the abundant seed cells in tooth tissue engineering, construct new research model for the micro-environment of the odontogenesis in vitro and vivo.

目的 本研究通过酶消化法分离培养脂肪干细胞，运用牙胚细胞条件培养液体外诱导脂肪干细胞向成牙本质样细胞分化，再将脂肪干细胞与成釉器上皮细胞混合接种入体内建立牙髓-牙本质复合体模型，证实大鼠脂肪干细胞的成牙潜能，为牙齿组织工程化研究获得大量、稳定、可靠的种子细胞提供理论和实验依据；并为体内、外成牙微环境的机理研究构建新的模型。

The dry seeds of Dendrobium nobile and Pleione maculata were cultured on MS, B5 and KC liquid media for inducing protocorms, and the protocorms were subcultured on MS, KC and B5 solid media to study the growth of protocorm differentiation seedlings in the different medium.

方法］将石斛兰和秋花独蒜兰的干种子培养于MS、B5、KC液体培养基上，诱导原球茎形成，再将原球茎培养于MS、KC及B5固体培养基中，研究原球茎分化苗在不同培养基上的生长发育情况。

Results showed that the frequencies of shoot regeneration of cotyledons explants from 4 d old in vitro grown seedlings were markedly increased from 34% to 46% via a preculture procedure of 2 days period using the media containing the hormone combinations of 2,4 D 0.5-1.2 g/L and 6 BA 0.2 mg/L.

结果表明，苗龄4d的幼苗子叶于含2，4－D0.5－1.2mg／L和6－BA0.2mg／L的培养基培养2或6d后再转到分化培养基上培养，芽再生率提高34％－46％。

The results showed that, using transient GUS expression, the frequency of resistant calli and shoot differentiation as a criteria, wheat mature embryos were cultured on the preculture medium of CM4C1P for 14 days, and immersed in inoculation suspension Ⅰ for 3 hours, then the explants were co-cultured under desiccation conditions for 3 days, which was optimal conditions for Agrobacterium-mediated transformation of wheat mature embryos.

为了进一步完善根癌农杆菌介导的小麦遗传转化体系，以小麦成熟胚为转化受体，研究了根癌农杆菌介导法转化小麦的主要影响因素，结果表明，以gus基因瞬时表达率、抗性愈伤组织获得率和分化率为转化指标，小麦成熟胚在预培养基CM4C1P上预培养14d后，用侵染培养液Ⅰ侵染3h，再经干燥共培养方式处理3d，是根癌农杆菌介导成熟胚转化的合适条件。

During the process of nuclear reprogramming, the zygotes of the normal embryos and the donor nuclei of thecloned embryos cease their unique repertoire of gene expression and reset their gene expression to the totipo-tent status, and then the normal and cloned embryos redifferentiate from the totipotent status to variousdifferentiated states for tissue generation or organogenesis.

通过细胞核重编程，首先，受精卵和克隆胚胎的供体核停止其特有的基因表达程序，恢复为全能状态的基因表达程序；然后，受精胚胎和克隆胚胎的细胞再从全能状态重新进入分化状态，最终形成各种组织和器官。

The reprogarmming of embryonic genome is likely the molecular foundation of the transition of highly differentiated oocytes into totipotential embryonic blastomeres.

基因表达的&再程序化&可能是高度分化的卵母细胞转变成胚胎中具发育全能性分裂球的分子基础。

［Objective］ To determine the sensitivity of Andrographolide in gastric cancer cell lines in various degrees of differentiation.
