Methods Mesenchymal stem cells were collected from the femora of SD rats by density gradient centrifugation and identified by flow cytometric analysis and alkaline phosphatase staining.

方法采用梯度离心法，分离纯化SD大鼠的MSCs，流式细胞仪检测和碱性磷酸酶染色鉴定细胞类型。

Methods: We transplanted neural stem cells from embryobrain of rats in hippocampi of AD model rats transecting fimbria fornix with or without FG.

目的：观察神经干细胞纤维蛋白凝胶支架移植治疗阿尔茨海默病模型的效果以及神经元分化的情况。

The sheer complexity of climate science, from atmospheric physics to polar glaciology, makes it harder to convey than some other science-based issues such as space policy, stem cells or HIV/Aids.

与太空政策、干细胞和艾滋病等其它一些科学问题相比，气候科学的极度复杂性--从大气物理学到极地冰川学--使其更加难以表达。

NEW YORK - Gleaning stem cells from cloned monkey embryos, as a team of Oregon researchers has done, is an impressive step.

纽约电——从克隆猴的胚胎中获取干细胞给人的印象非常深刻。俄勒冈州的一个科学家小组就是这样来提取干细胞的。

Findings from these studies reveal that neural stem cells are self-renewing, multipotent progenitors that give rise to the diverse types of neurons and glia.

NTD的发生与神经干细胞的增殖、细胞的粘附分子、神经细胞的迁移等有关的分子信号的改变或作用途径被阻断密切相关。

In the closed position, they are seated by thrust from the stem like a globe valve.

在关闭状态下，这种阀门正如截止阀一样，通过阀杆推力将阀座封闭住。

The Stem Extension is made to accept the handwheel from the valve to which it is being attached.

所制造的阀杆加长件能够配合阀门上的手轮。

Because genetic engineering has the potential to conquer cancer,grow new blood vessels in the heart,block the growth of blood vessels in tumor s,create new organs from stem cells and perhaps even reset the primeval genetic coding that causes cells to age

因为遗传工程有可能征服癌症，在心脏里培植新的血管，阻断肿瘤中血管的生长，从干细胞中选出新的器官，甚至可能重组可以延长细胞寿命的原始遗传编码。

Now it is generally accepted that CD34〓 cells represent stem cells and progenitor cells. CD34〓 cells are better target cells for studying regulation of hemopoiesis, as they are relatively homogenous, compared with mononuclear cells seperated from bone marrow or blood.

目前普遍认为CD34〓细胞代表造血干细胞和祖细胞，因为与骨髓或血中分离的单个核细胞比较，具有相对的均一性，在造血调控的研究中是一个较好的靶细胞。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
