软骨的

In recent years,masenchymal stem cells have been applied in cartilage tissue engineering and they have shown significant potenital for carriage repair in animal models,and are being used as an ideal cell source in cartilage tissue engineering.

：间充质干细胞具有高度自我新能力，能够分化各类型的细胞近20年间充质细胞在软骨组织工程中得到应用，动物实验显示了良好的软骨修复潜能，成为软骨组织工程的理想的细胞来源。

The experimental results are analyzed using the virtual linear viscous theory and the constitutive equation is established for the fibrocartilage.

通过对新鲜腕关节软骨板共计60个试件进行不同应变水平下的"应力松弛试验"和等应变速度下的"拉伸试验"，了解腕关节软骨板在承受一维拉伸破坏试验时的力学性质，并用拟线性粘弹性理论对试验结果进行分析，建立了腕关节软骨板的本构方程。

In one way, autologous catilage, allogeneic fresh and preserved cartilage with or without perichondrium, preserved human cartilage with or without perichondrium were implanted in the back subcataneous of the same rabbit.

一方面，将自体软骨、新鲜的和培养的同种异体带膜及不带膜软骨以及所培养的人的带膜及不带膜软骨移植于同一兔背部，分别于7天、30天、60天、90天、120天、150天、180天、200天、300天及370天时取标本观察移植效果。

There hae been a few reported cases of bursal osteochondromatosis inoling the retrocalcaneal, subacromial, and subcoracoid bursae2,10,11; howeer, infrapatellar bursal osteochondromatosis has neer been reported in the English-language literature, to our knowledge.

已报道的粘液囊骨软骨瘤病病例包括跟骨后、肩峰下及喙突下粘液囊的骨软骨瘤病；然而，据我们所知，髌骨下粘液囊骨软骨瘤病的报道却从未在英文文献中见到过。

For both genes, highest expression was found for costal chondrocytes, followed by nasoseptal, articular, and auricular cells. Retrieal of 20-week discs from mice reealed changes in construct dimensions with different chondrocytes.

就同一种基因而言，肋软骨来源的软骨细胞表达最高，其次是鼻中隔，关节以及耳。20周后从裸鼠皮下回收的不同软骨细胞来源的圆盘样组织在体积上也有变化。

Ever since, people tried their best to find a way to reconstruct articular cartilage. Following the maturity of cultivation technology on chondrocyte and the development of medical organic materials, technology of tissue engineering come to show its superiovity in articular cartilage plerosis.

多年来，人们一直试图修复或重建软骨组织，随着软骨细胞培养技术的成熟及医学生物材料学的飞速发展，组织工程技术在软骨修复中显现出无与伦比的优势。

Methods Fifty healthy SD rats were fed for twentytwo months in order to build the model of aging rats, the histology of femoral bone, tibial bone and lumbal vertebra was used to observe, then we evaluated the indexes which reflect the degeneration of intervertebral disc including the quantity of collagen type Ⅱ,Ⅹ of intervertebral disc by the immunohistochemistry methods, the relative area of vascular bud, the thickness of calcified layer and uncalcified layer on cartilage endplate and the indexes which reflect the osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the bone density, the max stress and straining of bone.

50只健康纯种SD大鼠，喂养22个月，建立老龄大鼠模型，进行股骨、胫骨、腰椎等组织学观察，并评价椎间盘退变的相关指标(椎间盘软骨Ⅱ型和Ⅹ型胶原表达、软骨终板血管芽相对面积、软骨终板钙化层/非钙化层厚度)与骨质疏松的相关指标(骨皮质厚度指数、骨小梁相对面积、骨密度、骨最大应力和应变)的相关性。

In conclusion, during the development of the mandibule, condylar cartilage derived from MSMPs at the end of the body mandibule. It can evolve into fibrocartilage cytes on appropriate condition and regenerate fibrocartilage provided with proper the three-dimension scaffold materials.

综上所述，下颌发育过程中，髁突软骨来源于下颌体部末端的骨膜间质细胞，此间质细胞在适当的条件下即可向纤维软骨细胞分化，并且此间质细胞在适当的三维支架中可再生纤维软骨。

Methods: the chondrocytes of the rabbit condylar were derived from rabbit,and were cultured to the second generation in vitro,then hgfcdna transfected the cells.the capacity of cell proliferation was tested by mtt,the deferences of the type ii collagen were tested by sabc immunohistochemical of the type ii collagen after infected;the mrna levels were tested nd so on the mrna levels were tested by in situ hybridization of the type ii collagen between the transfection group and comparison group .

取兔膝关节软骨细胞体外培养至第二代，hgfcdna转染软骨细胞，空白质粒组为对照组；噻唑蓝检测软骨细胞的增殖能力，sabc免疫组化及原位杂交法测其ii型胶原在转染前后的变化与mrna的表达。
