Objective: To study the angiogenesis promoting effect of Sexiang baoxin Pill on chicken embryo chorioallantoic membrane and cultured microvascular endothelial cells.

目的：探讨麝香保心丸在鸡胚绒毛尿囊膜模型及培养的微血管内皮细胞系统中的促血管生成作用。

We also found an angiostatin-like protein and the detection of its activity on chick embryo chorioallantoic membrane model shows a sign of inhibition of the positive effect of lung cancer cell culture supernatant on CAM.

对angiostatin类蛋白的功能鉴定结果发现在一定程度上可以抑制A459肺癌细胞培养上清对鸡胚尿囊膜血管生长的促进作用。

The purified immunoglobulins were effective in the inhibition of endothelial cell adhesion, proliferation and angiogenesis in chick chorioallantoic membrane in vitro, and in anti-tumor activity by the adoptive transfer in vivo.

将该抗体纯化后，纯化的免疫球蛋白可以有效地抑制体外内皮细胞的粘附、增殖和鸡胚绒毛尿囊膜的新生血管形成，体内过继输入治疗亦可引起抗瘤效果。

METHODS: In september 1999, human embryonic tendon cells and artificial materials were co-cultured in vitro to construct tissue engineered tendon, which repaired coracoclavicular ligament injury.

1999年9月采用人胚肌腱细胞与材料体外复合培养，构建组织工程化肌腱，修复喙锁韧带损伤。

At globular embryo stage, calcium concentrated on plasma membrane and certain areas of cytoplasm; at cotyledonary embryo stage, calcium presented on cell wall and intercellular space.

胚性愈伤组织细胞的ATP酶活性高，定位于细胞壁、胞间隙、质膜及细胞核，为物质的吸收和积累提供能量。

We propose that the noncell-autonomous effects of Spemann's organizer on dorsoventral patterning are executed in part by diffusible signals that directly bind to and neutralize ventral BMPs during gastrulation.

我们提出，施佩曼组织器对背腹式的非细胞自发功能，有部分是通过原肠胚形成过程中，直接结合和抵消腹部BMP的扩散性信号所发挥的。

The dult stem cells abilities of differentiation, self-renewing and self-maintenance tended to be limited so that it, which is characterized of short life time, could differentiate by means of mono-direction or double direction. What is the most important is that it can not differentiate all cells from the three embryonic layer.

成体干细胞具有一定的生长期，其分化能力、自我更新、自我维持能力具有局限性，生存时间相对较短，仅能单向或双向分化，其重要特点之一是它不能分化成机体所有的三个胚层来源的细胞。

On the base of review the research development in tissue culture and genetic transformation, Comparative analyses were made on the callus induction and embryogenetic abilities of anther and non-pollinated ovules of rubber tree. Fluorescence detection was implemented with the different in vitro material of Hevea brasiliensis.

本研究在综述了橡胶树组织培养及遗传转化研究进展的基础上，系统地比较了橡胶花药和未授粉胚珠愈伤组织诱导及体细胞胚胎发生能力，对橡胶树不同离体组织进行荧光背景检测，将在植物胚胎发育时期起重要作用的BBM基因导入橡胶树，对电激法转化游离小孢子细胞以及农杆菌介导花药愈伤组织进行初步探索。

Embryogenic suspension cell is ideal material of protoplast culture of gramineous plants.

胚性悬浮细胞是禾谷类作物原生质体培养的理想材料。

During somatic embryogenesis, we were able to trace the FAC1 expression to single embryogenic cells, suggesting its critical role in early induction.

FACl在体细胞胚胎发育过程中的表达可以追踪到单个的胚性细胞，说明它在激活早期胚胎发育中的关键地位。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
