在生物体外

In vitro cell culture cells adsorption and growth were also carried out in this paper, which the cell adsorption and morphology were acquired with a phase contrast microscope.

同时也通过体外细胞培养的方式研究了胺基生物功能薄膜对细胞黏附以及细胞生长的作用，并在倒置显微镜下观察细胞的黏附以及生长情况。

Then PLGA Micro spheres can promotes the proliferation of osteoblast in a long perlod because of the controlled release of bFGF from microspheres. The PELA microspheres satisfied the proprty reguirement of controlled release, but the biological activity of the released bFGF is partially destroyed.

2体外细胞试验中，游离bFGF对成骨细胞具有促分裂增殖的作用，但效应期很短；而PLGA微球通过持续释放活性bFGF，可在较长时期内促进成骨细胞的分裂增殖；PELA微球虽然达到了缓释的性能要求，但释放出的bFGF的生物活性受到了破坏。

During the course of culture in vitro, the biological function of human nasal septal cartilage gradually degrade in accordance with increasing times of passage, chondrocytes after the third generation are not suitable for human cartilage tissue engineering seeds or studying cytobiology.

人鼻中隔软骨细胞在体外培养过程中，随传代次数的增加而功能活性逐渐降低，第3代以后的细胞不适于作为人软骨组织工程种子细胞和用于细胞生物学等方面研究关键词：葡萄糖氨基浆糖类；软骨细胞；细胞外基质；生物材料

The core technology of tissue engineering is utilize the suitable seed-cells compound with organic materials to build a cartilage-like tissue in vitro or in vivo, this tissue must be similar with hyaline cartilage in forms、structure and behavior.

软骨组织工程的核心技术就是利用合适的种子细胞复合生物材料，在体内或体外构建与人关节透明软骨形态、结构、性能相似的软骨样组织，用于软骨移植。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
