This experiment approach rat-MSCs which are fractional cultivation、generation in vitro, and in Chinese crude drug circumstance to derivationrat-MSCs chondroblast differentiated, to explore the front view ofcartilage coloboma architecture engineering recovery by Chinese crudedrug.

本实验探讨大鼠骨髓间充质干细胞在体外分离培养、增殖，以及在中药环境下诱导向成软骨细胞定向分化，探索软骨缺损组织工程修复中的中药应用前景。

In resent year, several in vitro models for committed differentiation of ES cells have been described which give rise to a variety of cell types, including hematopoietic, neuronal, chondroitic, osteocytic, endothelial, myogenic, cardiac and smoothes muscle cells, but the committed differentiation into epidermal stem cells have not been reported.

但定向分化为表皮干细胞至今未见报道。

The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

利用CT和立体定向仪对20例甲醛溶液固定的头颅标本标记斜坡中央凹陷区中心点，采用FLA入路，骨切除分四步进行：磨除颈静脉结节，部分乳突切除，枕髁全切，C1侧块切除；分别于每一步骨切除及血管神经牵拉完成后测量斜坡中央凹陷区的显露范围和位于中心点上方15 cm处术者的操作范围。

Methods Central point at the central clival depression was marked with the help of CT and stereotactic apparatus in 20 formalin-fixed cadaveric heads. The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

Rectangle stripe-like alignments of 3D CNTs, with a feature of high resolution, were controllably fabricated by a shadow mask and vacuum deposition of a metal catalysis.

采用掩模和镀膜技术，可控性地构筑了具有高分辨率的条纹状的三维纳米管阵列图案，实现了碳纳米管的定位和定向生长。

Then, the proliferative ability of OPCs in vitro was also investigated with the MTT assay.4. The contusive injury of spinal cord in a rat model was produced by the means of the weight-drop impact of Allen's method. The experimental animals were randomly divided into 4 groups, i.e. OPCs transplant group, transplant control group, plain injury group and sham operation group.

OPCs在体外化学条件培养基中继续生长，通过相差显微镜连续观察和免疫细胞化学技术检测研究分析体外条件下OPCs的定向分化规律和分化成熟情况，并采用MTT检测法研究分析OPCs在体外条件下的分裂增殖能力。4。

The whole brain of the subject was axially and coronally scanned in the normal stereotactic space with a slice 1mm thick by MR system. The caudate nucleus were identified, segmented, extracted, saved and three-dimensionally reconstructed on MRI by software system developed by Research Center of Biology, Harbin University of Technology.

在以AC-PC线为基准线的标准脑立体定向空间对志愿者做1mm层厚，间距0mm的MR轴位和冠状的脑扫描，利用哈尔滨工业大学生物研究中心研究开发的软件系统对经MRI扫描后转存的尾状核图像进行三维重建，软件提取分割的尾状核轮廓后执行重建命令。

Experiments are performed to confirm the chemical etching method for defining the crystallographic orientation of silicon single crystals.
