In this study, the effect of nCDHA on chondrogenic differentiation of rat adipose-derived adult mesenchymal stem cells in alginate gel was evaluated. nCDHA/alginate composites containing different amounts of nCDHA were prepared and used to encapsulate rat ADAS. The chondrogenic differentiation of ADAS was enhanced after 7 days and the total collagen content increased after 14 days at 500 ppm of nCDHA.

In present study, we discussed the effects of cell microfilament on the activity of collagen type I alpha 1 chain gene (COL1A1) promoter under microgravity simulated by clinostat and/or cytochalasin B as microfilament depolymerizer in the established EGFP-ROS cell line using the method of fluorescence semi-quantitative analysis and the fluorescent stain of microfilament.

但微重力对相关基因调控的影响知之甚少，本研究以构建的基因工程细胞株为对象，以回转器模拟微重力效应，利用增强型绿色荧光蛋白（enhanced green fluorescence protein，EGFP）荧光半定量和细胞微丝荧光染色分析技术，探讨回转模拟微重力条件下，细胞微丝系统对I型胶原α1链基因（collagen type I alpha chain 1，COL1A1）启动子活性的影响。

The results showed that Gypenosides itself did not affect platelt ultrastructure, but coult inhibit platelts from changes in the shape of platelet, pseudopodium formation and granule release during aggregation induced by ADP, arachidonic acid and collagen, suggesting that Gypenosides are a inhibiter of platelet function.

结果表明，绞股蓝总皂甙本身对血小板结构无影响，但可抑制ADP，AA，Collagen诱导的血小板外形的改变，伪足的形成和颗粒的释放。进一步证实了绞股蓝总皂甙对血小板功能的抑制作用。

The rezults showed that SAOH itself did not affect platelet ultrastructure and aggregation, but could inhibit platelet from changes in the shape of platelet,pseudopodium formation and granule release during aggregation induced by arachidonic acid , collagen and ADP, suggesting that SAOH are a inhibiter of platelet aggregation.

结果表明：倒卵叶五加总皂甙本身对血小板聚集和超微结构无明显影响，但可抑制AA、Collagen及ADP诱导的血小板聚集、外形改变、伪足形成和颗粒的释放。

Adipocytes in bone marrow cavity could decrease the activity of ALP, weaken the expression of Collagen Ⅰ mRNA, inhabit osteogenic potential of bone marrow stromal cell, and induce apoptosis of bone marrow stromal cells.

髓内脂肪细胞可降低骨髓基质细胞内ALP活性，减弱CollagenⅠ mRNA表达，干扰其成骨能力，并能诱导骨髓基质细胞发生凋亡，在骨质疏松症的发病中有着重要的意义。

Perceptively on 3d and 5d. Collagen is positive in Western blot on 9d. Aniline dyeing is positive on 12d. The control group was negative. Ad-BMP-2 transferred MSCs cultured in fibrin gel was positive in Aniline dyeing, Immunohistochemical. The therapy effect of group was better in histology, biochemistry and biomechanics in all periods than the other two groups, and was similar to the natural cartilage.

结果 ①Ad-BMP-2转基因MSC BMP-2、CollagenⅡ的PT-PCR分别在3、5d呈阳性，CollagenⅡ的Western Blot 9d为阳性，较对照组有显著差异；②转基因MSC经纤维蛋白体外三维培养后免疫组化和苯胺蓝染色呈阳性，电镜显示细胞生长良好，有基质合成；③转基因修复组各时期大体、组织形态学和组织化学成份均显著优于其它两组，12W时力学和组织学已接近正常关节软骨。

从成分上来讲，天然骨除了含有羟基磷灰石无机成分外，还含有胶原(collagen，Col)、糖蛋白、糖胺聚糖等少量的有机成分无机物与有机物含量之比约为7∶3，其中胶原占有机质重量的90%犤2

During the ESR study of the effects of oxLDL on the ESR signal intensity of hydroxyl radicals in collagen (2 μg/ml)-activated platelets, we found that incubation of human platelets with collagen produced a typical four-line hydroxyl radical signal and a long-lived g = 2.005 radical detectable by spin trapper 5,5-dimethyl-1 pyrroline N-oxide.

在研究oxLDL降低由collagen 〈2 μg/ml〉刺激血小板产生的氢氧自由基〈OH●〉的ESR讯号强度的同时，我们发现以DMPO当自由基捕捉剂，collagen除了刺激血小板产生一个四线的典型氢氧自由基之外，还产生一个长半衰期 g = 2.005的自由基。
