spindle stage 中文意思是什麼
spindle stage
解釋
旋轉針臺-
Anaphase the stage in mitosis or meiosis when chromatids are pulled toward opposite poles of the nuclear spindle
後期:在有絲分裂或者減數分裂過程中染色單體分別朝相反的兩極運動。 -
The mice showed also ageing - associated decline in oocyte quality, as indicated by increased frequency of premature chromatid separation, spindle disruption and / or chromosome misalignments in mii oocytes of aged mice. the gv oocytes from aged mice normally matured in vitro. the percentages of pronuclear - stage embryos, 2 - cell embryos and blastocyst derived from mii oocytes of aged mice by in vitro fertilization ( ivf ) were comparable with ones of young mice, but pronuclei formed 1 h later in aged mice than in young mice
老齡小鼠gv期卵母細胞能正常體外成熟；老齡小鼠m期卵母細胞經體外受精后形成原核期胚、 2 -細胞期胚和囊胚的比率與年輕小鼠比較無顯著差異，但原核形成時間延遲1小時；在老齡小鼠卵母細胞，注射牛精子抽提物或sr ~ （ 2 + ）處理時所誘發的ca ~ （ 2 + ）振蕩以及在減數分裂成熟及早期胚胎中的pkc分佈未發生改變。 -
W7 was added when the cells entered anaphase, we found that although some cells had elongated, the distribution patternof cam at central spindle was normal, and it seemed that a cleavage furrow would possibly form soon, however, these cells stopped cytokinesis at this stage, no furrow ingression followed
在細胞進入有絲分裂後期時，加入w7 ，我們發現有的細胞雖已拉伸變長，中區紡錘體處也有gfp cam的分佈，存在形成分裂溝的跡象，但分裂溝卻不繼續縊裂加深。 -
3. when the cells were treated with w7, a ca2 + / cam inhibitor, the central spindle assembly was affected, and the abnormal central spindle was formed ; besides, when w7 treatment was applied at an early stage of cytokinesis, the division furrow index would decrease substantially. these results show that cam is really involved in the regulation of furrow formation and this involvement may be fulfilled by regulating the dynamic structure of central spindle
我們利用w7抑制cam活性，發現cam活性喪失會引起中區紡錘體結構異常；如用w7處理同步化于胞質分裂早期的細胞，可使細胞的分裂溝形成指數明顯下降，這表明cam的確參與調控了分裂溝的形成，而且可能是通過調控中區紡錘體的動態結構參與這一過程的。 -
5. the position of buffalo oocyte nucleolus related to its pb1 during the final stage of ivm, and the feasibility of increasing enucleation rate using spindle - view system were studied. the space between pbi and spindle ( sp ) of ivm buffalo oocytes increased as the ivm duration prolonged
9 ， 64刀） ，但當成熟時間增加到24h時，這一比例下降到57石（ 726 vs57石， p 0刀5 ） ，如採用spindle view系統去核貝可消除這種位置變化對去核率的影響。
