embryonic layer 中文意思是什麼
embryonic layer
解釋
胚層-
We deduce frondose algorithm of three layers bp neural networks which is used in common, and discuss several important issues in designing neural networks which is used to forecast, for example, number of hidden layer, nerve cell number of hidden layer, epoch of learning, embryonic power value, decision of node number about input and outputo at the same time, this dissertation sums up things that conventional bp algorithm is improved on considering disadvantages of it
3推導了常用的三層bp神經網路具體演算法，討論了實際預測應用中神經網路設計方面的幾個重要問題，如隱層數、隱層神經元數、訓練次數、初始權值、輸入節點數以及輸出節點數的確定。同時，針對傳統bp演算法存在的各種各樣的缺點，文中綜述了對其改進的情況。 -
The quality of feeder layer is affected by a lot of factors, such as animal breed, culture medium, passages in vitro and experiment condition, etc. as to the production of feeder layer, there are a few reports about morphological and histologic change when of embryonic body fibroblast when culturing in vitro and cryopreservation, so kunming mouse were chosen as experimental animals and morphological and histologic changes were studied in course of its embryonic body culturing. we expect to offer theoretical foundation to our laboratory for setting up feeder layer storehouse. at the same time, the feasibility of myocardium tissue culturing with fibroblast layer altogether was studied so that established foundation for studied the biological characteristic of heart outside body
小鼠胚體成纖維細胞的培養是制備飼養層的重要途徑，其制備、傳代及冷凍保存均有不同的研究報道，飼養層的質量受許多因素的影響，如動物的品種、培養液、所傳代數及實驗條件等，關于飼養層制備過程中的胚體細胞培養、傳代、冷凍后的細胞形態、組織學等方面的研究報道很少，故本實驗以昆明小白鼠為實驗動物，研究其胚體培養過程中細胞的形態學、組織學等方面的變化，以期為本實驗室建立飼養層細胞庫提供理論依據，同時探討心肌細胞和成纖維細胞層共培養的可行性，以期為心臟生物學特性的體外研究奠定基礎。 -
The primary primordial germ cells is obtain from the human embryos after 4 - 8 weeks of pregnancy. after mechanical desection and enzymic digestion, the cells were cultured on mouse embryonic flbroblast or human embryonic flbroblast feeder layer inactivated by mitomycin. the medium contains several cytokines : lif ( leukemia inhibitory factor ), bfgf and foskolin
從4 ? 8周的流產胎兒的原始生殖嵴部位分離到原始生殖細胞，經過機械和化學方法的解離后培養於事先用絲裂黴素處理過的小鼠胚胎成纖維細胞或人胚胎成纖維細胞飼養層上，培養基中添加了lif ， bfgef ， foskolin等細胞因子，此後大約每7天左右傳代一次。 -
Thus, it was evident that, as in embryonic mice, the proteins play a crucial role in the maintenance of cells in the region, and revealed a previously unknown function for them in assuring ependymal layer integrity
因此，它證實了，在胚胎小鼠，該蛋白在維持這個區域的細胞扮演著重要的角色，同時揭露了先前無人知曉的確保室管膜層完整性的功能。 -
We also investigated the factors including feeder layer cells, growth factors and complements, which may affect the cultivation and differentiation of these cells in vitro. the main contents as follows : ( 1 ) isolation and culture of mouse embryonic fibroblast ( pmef ) and preparation the feeder layers
主要內容包括： （ 1 ）小鼠胚胎成纖維細胞（ mef ）的分離培養和飼養層細胞的製作以妊娠13 . 5天或14 16天的小鼠為材料，建立了mef分離培養體系。 -
The blastocyst was obtain from the mouse after 3. 5 days of pregnancy, and was cultivated on the mouse embryonic flbroblast feeder layer. the blastocyst usually attach to the feeder layer after 48 hours, then the inner cell mass began to grow and form a big cell mass of embryonic stem cells. these cells can form cell clones with the conformation of embryonic stem cell
囊胚一般在48小時后貼壁並脫去透明帶，由囊胚中的內細胞團增殖形成一個胚胎幹細胞球，待其生長至一定程度后對其進行酶解傳代，在傳代后的細胞中重新生成es集落形態的細胞集落，在集落生長至一定程度后再進行傳代，此後大約每5 ? 7天傳代一次。
