Objective To establish the spontaneous differentiation culture system of embryonic stem cells in vitro and provide methodological and morphological basis for the directional differentiation of ES cells.

目的建立胚胎干细胞(embryonicstemcells，EScells)体外非定向分化培养系统，为其向各种成熟细胞的定向诱导分化提供方法学和形态学基础。

At the same time, a fertilized ovum to the uterine cavity gradually moving ,3-4 days after the arrival of intrauterine growth when cells become more than an entity, shaped like mulberry, so called morula.

与此同时，受精卵逐渐向宫腔方向移动，3—4天后到达宫腔时已发育成为一个具有多个细胞的实体，形状象桑椹，所以称为桑椹胚。

Our result showed that the tissues of neurodermatitis witnessed chronic inflammatory reactions, including infiltration of inflammatory cells, migration of Langerhans' cells to dermis and up-expression of CD40, all of which correlated to the seriousness of the disease.

结果显示神经性皮炎组织呈现慢性炎症反应，炎症细胞的浸润，LC向真皮迁移以及CD40分子表达增加，这些均与疾病严重程度相关。

However, we can reconstitute the biosynthetic pathway by supplying the cells with catalytically active polypeptides.

但是，我们可以通过向细胞簇提供催化活性肽来重建生物合成的途径。

When cells were illuminated Ca〓 exfluxed from mitochondria to cytoplasm (Roux et al 1981). Therefore, Ca〓 may be an active factor in the regulation of green cell metabolism under the condition of illumination.

照光时Ca〓从线粒体向细胞质排出（Roux et al 1981），因此Ca〓在调节照光时绿色细胞的代谢中可能起重要作用。

Growth curves of different passges (P=5 and P=10) of rabbit MSC were drawn according to the MTT test. Modified Woodbury protocol was adopted to induce the neuron-oriented differentiation of rabbit bone marrow-derived MSC, that is, BME was applied to MSC in low dose and a relatively short span (D=3mM, and T=2h).

尝试使用膜片箝全细胞记录的方法记录诱导前后MSC的钾离子电流的变化，以反映细胞的电生理功能郑州大学20抖年硕士研究生学位论文间充质干细胞的体外培养及向神经元的诱导分化状态。

Anaplastic'.'' cells that tend to invade surrounding tissue and metastasize to new body sites.

Any of various malignant neoplasms characterized by the proliferation of anaplastic cells that tend to invade surrounding tissue and metastasize to new body sites.

癌症一种恶性肿瘤，其特征为退化细胞侵入周围组织和向新的身体部位移转并大量增生

Results showed sTGC-CM, which is similar with the effect of hTGC-CM, was able to induce human DPSCs to make odontoblastic changes as indicated by remarkable morphological changes, increased proliferation ability, higher multipotential and colony forming capability, and expression of some odontogenic markers in gene and protein levels,such as DSP, DSPP, DMP1, BSP, OCN, OPN.

结果表明：人牙髓干细胞经过一定时间的猪牙胚条件培养基诱导后，能在细胞形态上和细胞周期上发生改变，能具有更高的克隆形成能力和多向分化能力，能维持更好的干细胞特性，具有更强的增殖能力，表达更高水平的碱性磷酸酶，免疫组化和RT-PCR提示诱导后的牙髓干细胞能在蛋白水平和基因水平表达出一些牙向分化的标志，如DSP、DSPP、DMP1、BSP、OCN、OPN等。

We find α-latrotoxin lowers the Ca~(2+) threshold required for exocytosis without the RRP change employed the ramp [Ca~(2+)]i stimulation generated by continuous UV illumination; Using combined techniques of membrane capacitance measurement and Ca~(2+) uncaging, we show that α-latrotoxin accelerates the fusion kinetics of the readily releasable pool of vesicles, and α-latrotoxin shifts the Ca~(2+)-dependence toward lower Ca~(2+) concentrations.

通过Ca~(2+)光解释放技术，我们也发现分泌的立即可释放囊泡库的分泌动力学明显加快，在同样的[Ca~(2+)]i下，α-latrotoxin使β细胞分泌的最大速度加大并且使β细胞的分泌与Ca~(2+)依赖关系向低钙方向移动。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
