  1. The primary results showed : using m199 as diluents containing 20 % bovine serum, it is better to freeze the cells slowly freezing at fist then increase freezing speed ( for example, from 0 to - 6 freezing speed is about - 0. 05 a minute, from - 6 to - 40, freezing speed is about - 0. 5 a minute ), studies on effect of various concentration of dmso demonstrate that about 12. 5 % dmso gave the highest post - thaw percentage of viable cells. the concentration of bovine serum had no different effect on the percentage of the viable embryo cells of misgurnus auguillicaudatus. the embryo cells derived 6 from the later stage of blastula offish is more resistant to the cryogen than the cells of early stage of blastula. the cells preserved in liquid nitrogen at - 196 were thawed and cultivated, a few cells were found adhere to the surface of culture vessel when the percentage of viable cell was more than 30 %. the cells in only two culture vessels were found to proliferated and gave rise to many small morphologically undifferentiated cells

    研究初步表明:以細胞培養液m199 （含2既的小牛血清，常規量雙抗）為凍存稀釋液對泥鰍胚胎細胞冷凍保存宜採取先慢后快的方式（例如，從0一一6 ，凍存速度為一0 . 05 / min ，再以一0 . 5 / min的速度從一6一一40 ） ; dmso的保護效應濃度為12 . 506左右;小牛血清的濃度對泥鰍胚胎細胞的成活率影響不明顯;囊胚晚期細胞抗凍性比中早期強;通過對不同批次的凍存細胞解凍培養，解凍后成活率為30 %以上細胞培養數天後均有少數細胞貼壁，但只發現兩瓶培養細胞有明顯增殖現象產生許多未分化的小細胞。
  2. Embryonic stem ( es ) cell lines isolated from primitive embryonic cells are highly undifferentiated and totipotent cells. in vitro, es cells can spontaneously differentiate into embryoid bodies ( ebs ) containing derivatives of three germ layers

    胚胎幹細胞（ embryonicstemcell ， escell ）系是從早期胚胎細胞分離培養而建立的高度未分化的具有全能性的細胞系。
  3. Among them, selenocosmia huwena and selenocosmia hainana belong to theraphosidae while macrothele raveni belongs to hexathelidae. all of them could kill insects and some small vertebrate with their venoms. in this article, using whole - cell patch - clamp technology, we observed the effects of the venoms from the three kinds of spider on the voltage - activated tetrodotoxin - sensitive ( ttx - s ) sodium current and delay - rectified potassium current of undifferentiated ng108 - 15 cells

    虎紋捕鳥蛛（ selenocosmiahuwena ） 、海南捕鳥蛛（ selenocosmiahainana ）和雷氏大疣蛛（ macrotheleraveni ）均是在我國近年來發現的蜘蛛新種，前兩者屬于捕鳥蛛科，而後者屬于異仿蛛科。
  4. Rather than injecting undifferentiated stem cells into damaged tissue, using precursor cells from a later stage of development - - ones already “ programmed ” to become retina or some other type of cell - - may be more successful, he says

    不是通過注射未分化的幹細胞進入損傷組織，使用來自發育後期的前體細胞（已經程序化成為視網膜或其他種類的細胞）可能更成功。
  5. Squamous cell carcinoma was dominant, followed by undifferentiated cell carcinoma, olfactory neuroblastorma and malignant lymphma

    病理以鱗狀上皮癌居多，其次依序為分化癌、嗅覺神經母細胞癌、惡性淋巴瘤等。
  6. Escs can be induced into neuron - like cells by sequential neural induction the undifferentiated escs grew in colonies, with clear bound. alkaline phosphatase staining showed dark brown positive particles were distributed in every esc colony. after the sequential neural induction, the cells converted into neuron - like cells, with homogeneous forms, which had round bright cell bodies and thin long bipolar or multipolar processes

    5誘導分化前後細胞端粒酶活性檢測（ trap ）結果1 .使用序貫誘導法可將escs大比例誘導分化為神經元樣細胞未分化的escs聚集成團狀生長，細胞排列緊密，集落邊界清楚，堿性磷酸酶染色呈強陽性，胞漿布滿棕黑色顆粒。
  7. The method inoles the use of protein markers under the control of cell - specific promoters to conert undifferentiated human embryonic stem cells into highly - specialized cells

    這種方法用細胞特異性啟動子控制的蛋白標志物使未分化人類胚胎幹細胞轉化成高分化細胞。
