It is to say that after amplificated a few autogenetic cells in vitro,we can make cell-scaffold complex when mix these cells with scaffold which has cytocompatibility and biodegradability.

同时，这种细胞—支架复合物无免疫原性，且拥有和自体组织类似的结构和功能，因此被认为具有广泛的应用前景。

I suspect this is a case of benign schwannoma, with characteristic spindled cells between collagenous stroma.

我猜想这例为良性神经鞘瘤，在胶原基质间为特征性的梭型细胞。

Note that the epithelial cells show no atypia and that there is a fine pink collagenous stroma within the papilloma.

值得注意的是上皮细胞未显示异型性且在乳头状瘤有清晰可见的粉红色胶原间质。

Human hsp90 genes are usually constitutively expressed in most mammalian cell types and can be further induced by...

热休克蛋白90（HSP90）在正常生长条件下细胞内就有较高水平的组成性表达，并可被热和丝裂原双重诱导。

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。

Another six specimens of each group was obtained for biomechanical test at 8 weeks. RESULTS: There were no significant differences between control group and fibrin group. In bFGF group compared with control and fibrin groups, appearance of the angiogenesis, fibroblast proliferation and collagen production in the sheath, epitenon and parenchyma at repair site occurred earlier and were more in quantity, the gliding excursion of the tendon was shorter, and the work of flexion and the ultimate tensile strength of the tendon were greater.

结果：对照组与纤维蛋白封闭剂组间各项观测指标比较均无显著性差别，与对照组和纤维蛋白封闭剂组相比，bFGF组修复部位腱鞘、腱外膜及腱实质的新生血管形成、成纤维细胞增殖较好，胶原的分泌出现早，数量也较多；肌腱滑动距离较短，屈曲功和肌腱最大抗拉力较大。

An administrative core unit will be set up with missions of taking care of all the exter

综合而言，以这样一个高度整合的研究计画，从临床、实验及治疗的方向在病人、细菌、细胞层次、和分子层次作系统性的研究，探讨热原性外毒素B及其他致病因子的功能，将会有助於我们对於A群链球菌的致病作用进一步了解，更重要的是这些资讯将会提供临床治疗的新策略。

The bodies have much greater potential to regulate spermatogonial stem cell proliferation and differentiation. The dosage of GFRα1 mRNA produced by undifferential spermatogonial cells regulates the signal transduction of glial cell-derived neurotrophic factor so as to regulates the direction of spermato gonial stem cells: at a low level, spermatogonoial stem cell favors differentiation; at a high level, spermatogonial stem cell favors self-proliferation.

GFRαl在小鼠生精恢复过程中以剂量相关性调控著胶质细胞源性神经营养因数资讯传人，从而调控著精原干细胞的去向：高剂量时诱导其增殖，低剂量时诱导其分化。

Results Of the 52 specimens, 38 were located in the ciliary body (73.1%), and 14 lesions involved the iris (26.9%). According to the results of histogenetic classification, the tumors of ciliary sensory epithelium were ranked the first place (20 cases, 38.5%) while malignant melanoma, the second one (14 cases, 26.9%) followed by melanocytoma (9 cases, 17.3%) and granulomatous lesions (5 cases, 9.6%).

结果 52例组织标本按解剖部位分类：位于睫状体病变38例（73.1%），原发于睫状体累及虹膜组织14例（26.9%）；按组织来源分类：占第1位者为睫状体神经上皮来源的肿瘤20例（38.5%），第2位者为恶性黑色素瘤14例（26.9%），第3和第4位者分别为黑色素细胞瘤9例（17.3%）和肉芽肿性炎性病变5例（9.6%）。

Results Microscopically, different degrees of hepatocytic degenerative changes and hyperplasic fibrous tissue and typical false lobule formation could be seen. Timm's staining result showed uneven distributed black granular deposits in the hepatocytes. No specific PAS staining was observed. Utrastructurally, the mitochondria were increased in volume and dramatically different in shape. The number of lysomes were increased.

结果 光镜下肝细胞表现为不同程度的退行性变，胶原纤维增生以及典型假小叶形成；Timm's染色阳性，发现不均匀分布黑色颗粒或团块样物质沉积；PAS染色则普遍缺乏特异性染色；超微结构显示线粒体形态多样，体积增大，溶酶体增多，粗面内质网管腔扩张，附着核糖体的脱颗粒，以及胞质水肿，质膜溶解。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
