色素母细胞

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

PONI skin health research centre, with advanced skin care technology and causes skin pigment, successful research and development of a "'8 'black-suppression, the corresponding treatment and conditioning" technology, not undermine, not suppressed, does not damage the ecology of the skin Under the circumstances, the skin pigment formation of a smart decomposition, hypnosis pigment cells, skin in a relatively short time, reaching Suji elegant, Whitening Source lucent effect, lasting effect, the relative safety of similar products increased 68 percent.

&8&重抑黑，对应疗理，彰显透亮白嫩！柏宁皮肤健康研究中心，结合先进的护肤科技和皮肤色素成因，成功推出&8重抑黑，对应疗理&科技，在不破坏、不压制、不损伤肌肤原生态的情况下，对皮肤色素形成过程进行智能分解，催眠色素母细胞，使肌肤在较短时间内，达到素肌雅致，净白透亮的效果，效果持久、安全性相对同类产品提高了68%以上。

The result is consistent with previous studies. Whereas, tapetal cells of sterile anthers were disintegrated since tetrad cells were disjoined, indicating that disintegration of tapetal cells is earlier occurred in sterile anther than that in fertile anther. DNA ladder revealed that the cleavage of nuclear DNA into oligonucleosome-sized fragments to

结果表明，在花粉母细胞减数分裂后的四分体解离时期，不育花药的绒粘层细胞较可育花药提前开始裂解；在不育系S-Mo17rf3rf3花药和花粉S-(rf3)中均明显出现PCD过程的DNA片段化以及线粒体细胞色素C外渗的现象，证明了玉米CMS-S的花粉败育与花药绒粘层细胞的提前凋亡和小孢子细胞的细胞程序性死亡有关。

In neurite outgrowth assays, the recombinant PEDF demonstrated neurotrophic activity by potentiating the differentiation of human Y-79 retinoblastoma cells as reported for the native PEDF.

於神经突生长检验中，这基因重组色素上皮因子以促进Y-79视网膜胚母细胞瘤细胞株之分化来表现其神经滋养活性。
