Histological observation: Four weeks after implantation, porcine cancellous bone scaffold/bone marrow stromal cells complex appeared new bone formation and scaffold's degradation, which significantly increased in 8 weeks; In 12 weeks, new bone continued to increase and changed gradually to mature bone, a small amount of the Havers system was seen, the trabecular bone was not typical, capillary proliferated obviously, few residual scaffolds were seen, and no inflammatory cells were observed.

组织学观察：猪松质骨支架/骨髓基质干细胞复合体植入后4周开始有新骨生成，支架开始降解；8周时新骨的形成及支架的降解都明显增加；12周时新骨继续增加，逐渐向成熟骨组织转变，可见少量哈佛系统，但骨小梁尚不典型，毛细血管增生明显，少量支架残留，未见炎症细胞。

Objective To determine the expression of CD44 in the liver tissue.Method 26 cases of liver cancer,16 cases of hepatocirrhosis and 5 cases of normal liver tissue were studied by HE stain and immunohistochemistry.

CD44是一种粘附分子，能介导细胞与细胞以及细胞与基质间的粘附，近年来的研究发现它与人体肿瘤的发生、发展及转移有着密切的关系，对肿瘤病人的预后判断具有重要的意义。

A part of microbial cells would autolyzed to release the intercellular alkanedegrading enzymes when they were cultured on alkane. Thus alkane could be degraded and synthesized alkane derivative with surface activity extracellularly. This surface-active agent would improve alkane emulsifying, and those unautolyzed cells could utilize the emulsified alkane sequentially.

微生物细胞在烃类基质中培养时，为了适应其疏水性环境以更好地摄取烷烃，会通过一部分细胞的自溶解体而使得胞内烃类代谢酶等释放，这样烃类在胞外被代谢生成具有表面活性的烷烃衍生物，该表面活性产物将促进烃类的乳化，使得剩余的未自溶解体的细胞可以借助生物表面活性剂而摄取降解烃类。

Adipose tissue-derived stromal cells have osteogenic activity after induction culture, which are able to repair bone defects combined with bovine decalcified bone.

脂肪基质细胞经诱导培养具备成骨活性，与细胞支架复合具备修复骨缺损的能力。

For this purpose, it is necessary to create scaffolds that can be degraded by osteoclasts and enable osteoblasts to build new mineralized bone matrix.

为了这一点，人们有必要创造一种支架，它不仅可以被破骨细胞降解也能让成骨细胞在其中生成新的矿化骨基质。

Results. Pleiotrophin immunoreactiity was seen in disc cells, endothelial cells, and in the extracellular matrix in most specimens of interertebral disc but was most prealent in ascularized tissue in prolapsed discs.

结果：多效蛋白表达在大多数标本的椎间盘细胞、内皮细胞和细胞外基质都得到了较好的表达，但表达最显著的还是在突出椎间盘的血管再生组织中。

Afterstage 17,most of PGCs migrated into germinal anlage,and only 3.2±1.8 PGCs per microliterappeared in blood.475.0±104.1 PGCs with a higher concentration about 7.28% were obtainedby preplating after 24h culture.

将胰蛋白酶消化后的性腺混合细胞培养24h，重新悬浮后将部分贴壁基质细胞除去，PGCs数量为475.0±104.1，比例为7.28％。

RESULTS: Transplanted AS had a favorable fusion between tissue-engineered skin and self-skin on the 3rd day after grafting with a few of ingrowths of capillaries.

结果：AS组在移植第3天，移植的组织工程皮肤与自体皮肤能够很好地融合，有少量毛细血管长入移植物，皮肤移植物颜色与自体皮肤颜色接近；随着时间的延长，移植物中毛细血管的数量逐渐增多，表皮层清晰可见基底层、棘细胞层、颗粒层和角质层，角化现象加强，有角化物脱落；真皮层细胞数量增多，网架逐渐降解，分泌的细胞外基质成份增多；第14天，创面基本愈合；修复区皮肤颜色与正常皮肤颜色非常接近，瘢痕很小，无需进行二次植皮。

The multiplication conditions of bone marrow stromal cells were respectively detected by fibroblast colony forming in vitro, tritiated thymidine {[3H]TdR} incorporation and MTT.

分别应用成纤维细胞体外集落形成法、[3H]TdR掺入法和四甲基偶氮唑盐法检测骨髓基质细胞的增殖情况。

OBJECTIVE: To investigate the possibility of differentiating functional insulin-producing cells from MSCs induced by DMSO.

目的：探讨二甲基亚砜对成年大鼠骨髓基质细胞定向诱导分化为胰岛样细胞团的作用。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
