在乳大鼠肝脏细胞的培养体系中，每隔24h收集培养上清并更换新鲜培养液，检测上清中酪胺的浓度；结果显示，每次更换培养液后，都能够在培养24h后的上清中重新检出酪胺，而细胞中检测不到酪胺。

And the effects of supernatant of transfected umb ilical blood cells were investigated alone or in coordinate with GM-CSF by colo ny formation test of human bone marrow cells in semisolid culture.Results SCF mRNA was expressed in transfected umbilical blood cells.

In the current human form, some cells are well fed, other cells underfed, and some not fed at all, which cause such cells to die over time.

在当前人类形体中，一些细胞被良好地供给，其他细胞缺乏供给，而另一些完全没有被供给，其导致了这些细胞随时间死亡。

The citric acid-producing strain Aspergillus niger 2363-2, was isolated and used in our research. The fermentation conditions were optimized as follows: sucrose as carbon source 8. 0-14. 0%, ammonium chloride as nitrogen source 3. 0-4. 0g/l, initial pH 2. 0, and cultural temperature 30℃. The influential factors of formation of spores were also studied, and a series of measures were taken to restrain the spore formation on the basis of our experimental results. With the consideration of the cultural environment and microbial cell itself, the factors affecting the duration of citric acid-producing activity of microbial cells were examined, and it is found that undissociated citric acid and the ageing of microbial cells are the main factors. The experimental results also show that partial replacement of fermentation broth can lengthen the duration of citric acid -producing acitivity of microbial cells.

筛选出了用于试验研究的柠檬酸发酵用菌Aspergillus niger 2363-2，确定了其最适发酵条件—碳源选用蔗糖，浓度8.0~14.0%，氮源为NH〓Cl，浓度3.0~4.0g/l，发酵初始pH值为2.0，培养温度30℃；讨论了分生孢子产生的影响因素，并通过试验提出了抑制分生孢子产生的措施；从分析微生物所处的环境和微生物本身两个方面出发，探讨了影响微生物菌体产酸活性持久性的因素，认为分子态柠檬酸和菌体本身的老化是影响微生物产酸活性持久性的两个主要因素，并提出采用部分置换发酵液发酵能延长微生物菌体的产酸活性。

It indicated that MyoD transfected ES cells can be induced into skeletal muscle cells unexceptionally by DMSO and one can gain plenty of skeletal muscle cells in vitro by this method.

说明通过MyoD基因转染再经DMSO诱导的方法可以从ES细胞获得大量骨骼肌细胞。

The observation showed that sterile plants and fertile plants in the pollen mother cell stage is not very different, when microspore mother cells of male sterile plants enter meiosis period, it could form normal tetrad cell , tetrad cell is normal in early development stage, In the uninucleate microspore stage , tapetal cells were vacuolization, the microspores were extruded to the middle by tapetal cells.

本研究利用石蜡切片法，结合光学显微镜技术对樱桃萝卜核质互作雄性不育系的不育株和对应保持系可育株的花药发育过程进行细胞形态学观察，观察结果表明：不育株与可育株在花粉母细胞时期差别不大，不育株的花药小孢子母细胞进入减数分裂期后，可以正常的形成四分体，四分体前期发育正常，而在单核小孢子期绒毡层细胞出现液泡化，绒毡层细胞向中间挤压小孢子。

Finally, cells that only produce identical copies of themselves are called unipotent. Like skin cells, when they divide, they only make more skin cells.

最后，那些只能复制它们自己的细胞就是单独型干细胞，像皮肤细胞，当它分裂的时候，它只能制造更多的皮肤细胞。

But in 2007, scientists made a revolutionary breakthrough. Three different groups simultaneously announced that they had converted unipotent, mature skin cells back into an undifferentiated state. In other words, they had created cells that behaved like embryonic stem cells without using any embryo derived materials.

可是在2007年时，科学家们取得了革命性的突破，三个不同的小组同时宣布他们能够把已分化、成熟的表皮细胞转会一种未分化的状态，换句话说，他们制造了一种类似胚胎干细胞的细胞，但没用到任何源于胚胎的原料。

This suggested there might have cis-acting element in 3'-UTR. In order to search the possible trans-acting factor, we found RNA-protein band in H〓 cells and no band in 95D cells using 3'-UTR probe by RNA EMSA assay. At the same time, this band could be competed with the unlabled probe. There was also no band obsearved using 5'-UTR probe in both cells.

为了寻找可能与3'-UTR结合的蛋白质反式作用因子，用RNA凝胶阻滞(electrophoresis mobility shift assay，EMSA)的方法，我们在H〓细胞的胞浆蛋白质提取物与3'-UTR探针的结合反应中，发现了一条RNA-蛋白质的结合带，而在95D细胞没有结合带出现；而且这种结合带能被未标记探针竞争性抑制；5'-UTR的结合反应也没有观测到结合带的形成。

When SA-bFGF-Math1 transferred to the epithelial cells(UEC-4) of utricle,these cells showed the potential to differentiate hair-cell-like cells.

通过脂质体将bFGF-Math1转染大鼠椭圆囊斑的上皮细胞(UEC-4)，可使其分化为新毛细胞。
